• Oplevering fase 1 De Kerk

    De verbouwing van de nieuwe entree van studentencomplex “De Kerk” is voltooid. Daarmee is de eerste fase van een totale opwaardering van het complex afgerond. Het uitgangspunt is om de bijzondere historische kwaliteiten beter tot hun recht te laten komen en tegelijkertijd het studentencomplex een jonger elan te geven dat aansluit bij zijn bewoners.

  • Nieuwe constructie voor Felix Meritis

    Bij de werkzaamheden aan Felix Meritis kwamen een aantal ernstige gebreken aan de bestaande constructie aan het licht. De oorspronkelijke constructies van enkele vloeren waren zover doorgezakt en ontzet, dat herstel daarvan tot meer schade aan het monument zou veroorzaken. Daarom zijn op verschillende plaatsen nieuwe stalen hulpconstructies aangebracht die de oorspronkelijk constructies ondersteunen én ontlasten.

  • Nieuw dak Felix Meritis gereed

    De nieuwe kapverdieping op Felix Meritis is aangebracht en de voorgevel gerestaureerd. Door de nieuwe kap is het oorspronkelijke bouwvolume weer herkenbaar. De fragmentatie van de dakverdieping, die is ontstaan ná de brand in 1932, behoort daarmee tot het verleden. Het nieuwe dak onttrekt de gebouwinstallaties aan het zicht en is uitgevoerd in zink. Door de lichte kleur is de kap ondergeschikt gemaakt aan de klassieke voorgevel. Het wit van de gevelbeëindiging met fronton in de voorgevel is overgeschilderd in een zandkleur die aansluit op het Bentheimer zandsteen, zoals het ook bij de oprichting in 1787 moet zijn geweest.
    Ook het dak van het centrale trappenhuis is vernieuwd. Dat dak is verlaagd zodat het weer een intermediar tussen de twee hoofdvolumes is. Carré en ovaal zijn weer herkenbaar, maar dit gaat niet ten koste van het daglicht dat zo prachtig in het centrale trappenhuis valt.

  • Villa Bloemcamplaan, Wassenaar

    This beautiful villa by architect Fokke van Duyn is characterized by a two-layer block in white color scheme, with a longitudinal saddle with low roof pitch. The closed façade at the front is broken by the stairwell that has been pushed out. The garage, in its original design clearly subordinating to the main volume, was rebuilt in 1971 and pulled into the living space. This part is of lesser architectural quality.

    Our client wanted a considerable enlargement of the living room. In the design it was decided to realize one clear extension to the main volume and to remove the original (remodeled) garage. Where the main volume consists of two layers with a hood, the L-shaped extension has a single layer.

    The extension is clearly recognizable as an independent unit through an architectural design: steel, glass and wooden louvre screens. The extension jumps in at the location of the connection to the main volume, which is made of glass, which continues as a skylight strip in the roof. The indentation creates a "hidden" side entrance at the front, and the valuable balcony solution on the floor remains free at the side.

    In line with the original starting point of Fokke van Duyn, the rear is open to the garden. The original building is mainly executed in white color tones. Natural material colors are used for the extension, so that the articulation is legible, and the main volume remains recognizable.

  • This forest cabin is located in a clearing on the outskirts of Vierhouten in the Veluwe. Because the house replaced an existing vacation home, restrictions were placed on the maximum allowable floor area.
    The rooms are arranged around a glass-enclosed patio, making the house feel exceptionally spacious despite its limited floor area. At the same time, this creates a buffer between the sleeping and living areas. Large sliding louvered screens can be used to create a more intimate atmosphere in the living room, the patio, or the bedrooms. When no one is home, these screens protect the patio from overly curious wild boars.
    The building is constructed using a wood-frame structure with open siding. Thanks to its robust detailing and the roof finish featuring natural slate laid in a random pattern, the building blends seamlessly into its surroundings.
    The design was developed in close collaboration with the clients and was completed in the summer of 2013. Since then, the house has been called “De Boshut.” It is very popular as a vacation home.

  • This residential complex is situated on a former industrial site in the middle of the village of Handel in North Brabant, Netherlands. The 12 rental apartments are built in two layers over a parking garage. Resolving the parking under the building gave us the opportunity to arrange the surrounding terrain as a communal garden.
    The spacious 2 and 3 room apartments all have a living room with a south-facing balcony. The staggering of the partly indoor balconies provides a pleasant undulation to the facade. On account of the municipal restrictions regarding height, a curved roof was chosen. To match the village architecture, a coarse red brick has been used with dark, inset joints. The roof is made of metal and is enclosed by spacious gutters.
    The building is centrally heated with a heat pump. The closed system uses a heat roof of 100 m2 and seven sources located at a depth of 100 meters. Geothermal energy provides heat, cooling and hot water in the homes. The heat exchanger in the roof keeps the system in balance. All houses have their own distribution unit with meters. Rainwater is purified and collected by means of a sedimentation facility in the garden. Together with the naturally ventilated parking basement, these are aspects that make the building particularly sustainable.
    This project was developed, designed and executed by MATH architects BV in one hand.

  • Workshop Taylor, New Jersey USA

    Following a landscape analysis, it was decided—in consultation with the owner—to replace one of the existing barns on this former farm estate with a new building featuring a one-person workshop, in which various mechanical engineering machines of antique value can be housed.

    The existing complex of farm buildings has remained intact, but unlike the existing “Barn-red” boarded barns, untreated red cedar was chosen. Through natural weathering, the building will blend into its surroundings over time. The wooden planks are installed horizontally and flush, with one plank protruding every three planks. This creates a strict horizontal rhythm that allows windows to be placed in various desired locations without disrupting the overall harmony of the structure.

    The facade is constructed around the laminated truss structure in a timber-frame design. The approximately 200 m2 workshop houses various specialties; for example, a “blacksmith forge” has been built in, and metalworking and woodworking machines have also been installed. The building is equipped with an underground exhaust system. Daylight can be remotely controlled via automatic sunshades above the skylights.

  • GEB-toren, Rotterdam

    The first "skyscraper" in the Netherlands from 1931 is, despite disastrous renovations in the 70s and 90s, a prominent national monument in Rotterdam. In the context of an upgrade of various student houses, Stadwonen asked us in 2016 to propose a design for both entrances and underlying spaces.

    Returning the original entrances is not possible due to the change in function. Moreover, the client has the express wish to make the design as open and transparent as possible, so that it "does justice to the monumental character of the building and sufficiently represents the young residents".

    In our design we try to do justice to the structure of the original building. The original composition of the façade is restored to its former glory, the special column structure becomes recognizable again. The elevator and staircase hall is stripped of all in between doors (that are later re-fitted), whereby the beautiful English staircase again takes a prominence. The open study center receives direct daylight through a window and is a reference to the public hall of the past. A new staircase provides a direct connection to the residents' space on the first floor and the communal roof terrace.

    The fully-built ancillary entrance, originally a passage for cars to the forwarding space located behind, is radically renovated on the inside. The client is willing to sacrifice one home for this, so that the entrance hall will have the original width of the passage. A wall-filling image with perspective is added to the back wall, suggesting extra depth. In the materialization, the components that fall within the original structure are kept high-quality but sober: the gray-white color scheme from the early years returns. Additions that do not belong to the original structure, such as the new element with the stairs and the various fixed furniture, are given a contemporary fresh material and color finish.
    In de materialisering worden de bouwdelen die binnen de oorspronkelijke structuur vallen hoogwaardig maar sober gehouden: de grijs-witte kleurstelling uit de beginjaren komt terug. Toevoegingen die niet tot de oorspronkelijk structuur behoren, zoals het nieuwe element met de trappen en de verschillende vaste meubels, krijgen een frisse materiaal- en kleurafwerking.

    After a staff change at the client has taken place, the "request" for the GEB-toren has been adjusted slightly. The emphasis here is on improving the appearance and the monumental character on the outside. We are currently also making a design for the other building entrances and the possibilities for original skylights from the basement are being investigated

  • Villa Sophialaan, Wassenaar

    The former doctor's residence on Sophialaan in Wassenaar was built in 1929 and designed by architect Wouter Mikmak.
    During the renovation, the existing house was preserved, and the spatial layout of the original design served as the starting point.

    The existing addition—a doctor’s office—which had undergone various modifications, was no longer functional. It was completely demolished and replaced by a sleek, geometric two-story box with a basement. Mikmak’s original spatial concept has been carried over into the new connections between the living spaces. For example, there is an open connection between the kitchen in the existing house and the garden room in the new addition.

    The addition is thus oriented toward the main building both functionally and spatially. A clear distinction has been made in the exterior design. This is particularly evident in the use of contrasting materials such as honed bluestone cladding, dark gray coated steel, and large glass surfaces.
    Naast het vernieuwen van de uitbouw is ook de zolder opnieuw ingedeeld, waarbij de bijzondere kapconstructie zichtbaar is gemaakt.

  • Residential House on Kerkstraat, Katwijk

    What began as a request for a second opinion grew into a complete design assignment for renovation and expansion of the building on Kerkstraat.

    The old house with forge was stripped of all disturbing 70s renovations. A new volume has been placed in the space between the two existing building volumes that is characterized by the use of glass and steel. This contrasts with the existing materialization of the building that is mainly made of brick and ceramic roof tiles.

    In the front section of the house, the original exposed beam ceiling has been preserved and remains fully visible.

    All of the existing rooms in the house lead into the combined living room and kitchen within the new extension, creating a clear and logical layout throughout the home. On the upper floor, a new landing connects the bedrooms located within the existing roof dormers. Oak wood and Belgian bluestone are used throughout both the original house and the extension, giving the interior a cohesive finish.

  • Studio Apartment, Den Haag

    This former post office in the Escamp district of The Hague, located at the end of a 1950s residential building designed by architect Piet Zandstra, has been transformed with simple interventions into a combined living and working space for a visual artist and a photographer. Restoring the building's original architectural qualities was an obvious choice, given the residents' passion for the design aesthetics of the 1950s, 1960s, and early 1970s. The ground floor has been designed as an open-plan space, with the layout organized around a wooden shipping crate that houses a workspace and an American-style kitchen beneath the oval skylight.

    In the former basement, a bedroom and bathroom have been created, illuminated by natural daylight through the existing basement light wells. The wide central area of the basement serves as a studio and receives daylight through three newly introduced openings in the ground-floor slab. These openings are covered with thick, transparent walkable glass panels, creating intriguing visual connections and spatial relationships between the two levels.

  • Kiefhoek J.J.P. Oud, Rotterdam

    The Kiefhoek in the Bloemhof district of Rotterdam is the last and most famous housing project by architect J.J.P. Old, that he made in the service of the Municipal Housing Service Rotterdam. De Kiefhoek is generally regarded as the plan in which he expresses his specific design principles of repetition, symmetry and color application in the most characteristic way. The district was built in 1928/30 and is shortly after the delivery nationally and internationally known as the "New Building" example.

    In 1983, the district received a major overhaul, whereby, among other things, the original wooden frames were replaced by plastic, the wooden fascia boards Trespa plating.

    Due to subsidence, one residential block of eight houses is already in such a state that it is technically impossible to save. In 1988, Wytze Patijn was commissioned to reconstruct this residential block on Hendrik Idoplein, so that the urban design was fully safeguarded. This block, which accommodates various housing types from a previous study and a museum home, will be the "laboratory" for the renovation / restoration for the rest of the Kiefhoek. Our agency is instructed by Wytze Patijn to take on specifications, working drawings and management.

    The residential block was completed in September 1990. After evaluation of the pilot project, it is decided to reconstruct the entire neighborhood with government and municipal subsidies. This solution was chosen because restoration while retaining the hull proved to be prohibitive, given the condition of the houses and in particular the foundations. A collaboration agreement has been concluded with architect Wytze Patijn for this project. Together, a reconstruction plan is designed in 3 phases. The plan is based on the housing types that have been developed for the pilot project of six houses on the Hendrik Ido block. New housing types have been designed for special places in the buildings. Furthermore, the plan contains 2 business premises at the characteristic points at the entrance of the district from the Groene Hilledijk. By merging homes into new types, 190 of the original 290 homes remain after reconstruction.

  • Residence J.J.P. Oud, Hoek van Holland

    J. J. P. Oud (1890 - 1963) was one of the leading figures of functionalism in the developed in Western Europe in the 1920s. As a member of "de Stijl", he tried to transfer the theoretical ideas of this movement to the practice of building and in all his work he was constantly looking for a synthesis between rationalism and aesthetics, technology and art, tradition and experiment.

    In the complex of workers' houses and shops in Hoek van Holland (design 1926), he said he succeeded best in bringing about this synthesis, which he called "poetic functionalism". The result garnered a great deal of international appreciation not only for the expressive environment and subtle use of color, but also for the quality of the floor plans. Some critics already praised it "perhaps the most beautiful monument of the new architecture".

    The complex was renovated in 1983, but the problems of moisture, cracking and loose plasterwork in the facades were not solved. The municipality of Rotterdam, owner of the complex, asked architect Wytze in 1994 Patijn for advice. Is M. Jaap van Kampen, an architectural firm, issued a recommendation for facade restoration in March 1995. The municipality hands over the complex to the Hoek van Holland housing association, which has been managing it for some time. They commission an additional, residential technical study. I.v.m. the costs are decided to perform the façade restoration in combination with a limited maintenance operation.

    Further destructive testing reveals that the condition of the steel gable beams is such that repair entails considerable additional costs. It is concluded that such an investment in small dwellings with a limited residential-technical future value is not wise. In September 1996, the "joining variant" was decided: 24 of the original 42 dwellings were left, 2 of which were in former stores beside the gate in the middle of the block.

    The discussions about the permissibility of such an intervention and the allocation of costs take almost a year. Ultimately, implementation can start in September 1998.

    Important elements of the intervention at body level are:
    - replacement of wooden ground floor floors with foamed concrete
    - steel supports of façade masonry replaced by concrete
    - (self-supporting) cavity leaf in front facade / concrete beam in rear facade
    - completely remove old façade layers and then apply a combination of exterior and interior facade insulation

    Building history research during construction revealed the original color the facade was not so much white but yellow-gray. The newly applied mineral plaster layer has this color. In one of the (retail) homes, interior elements and are in good consultation with the residents colors processed, as found during research.

  • Student house De Kerk, Rotterdam

    The former church on Goudse Rijweg in Rotterdam was damaged by fire in the 1970s and subsequently radically converted into a student housing complex. As part of this conversion, two wings were built perpendicular to the nave. MATH has developed a vision for the complex that allows the building to be upgraded in phases and better showcases the original architectural quality of the church. This vision is being developed and implemented in phases.

    Renovation of the entrance area began in April 2018 and has since been completed. Behind the brass-clad entrance door, the former church porch is once again fully illuminated. The structural elements from the 1970s are clad in sustainable bamboo, as is the new partition featuring the mailboxes. Both elements evoke the original wooden furnishings found in a church and contrast with the white and gray tones of the original church. Fresh accent colors and a sophisticated lighting design complete the design: an almost mystical atmosphere is created in the entrance hall.

  • Residential Complex, Heindijk

    The renovation of the plinth is part of the total renovation of the complex that consists of four residential buildings around two inner areas. The complex was in a poor state that was partly prompted by social circumstances. In addition to structural renovation, the assignment has been made to contribute to improving the social climate.

    After a thorough analysis of both the buildings and the urban development situation, a total plan was made in collaboration with landscape architect Carin Jannink. The rentable spaces in the plinth strip play an important role in this. The entrances are characterized by robustness and transparency. The storerooms are designed as circuits and accessible at all angles.

    The entrance halls of two flats will be moved to the end, so that they will be located on the inner area. The entrances are equipped with a spacious landing and equipped with spacious roof overhangs with an expressive roof edge of UNP profile. The interplay of lines responds to the stratification of the façade surfaces of the flats. At the location of the stairwells, glazed facades have been raised to the highest roof edge, giving the entrance a more impressive appearance in the whole. Openness is achieved by creating transparency in both horizontal and vertical directions.

    A color and material design has been made for the entire complex. The basis for this is a reserved color scheme in shades of gray with accents in blue and green. The balustrades are alternately executed in dark bar fences and opal glass. Green or blue glass has been used at the location of the gallery ends. The concrete bacon bands in the façade, which are so characteristic of the flats from this period, are painted fresh gray-white.

  • Havenlicht, Pernis

    On behalf of SOR, a foundation which deals with the housing of the elderly, we made a sketch-plan to obtain a subsidy for the construction of a “district care center” in Rotterdam-Pernis. When the grant was assigned at the end of 2003, we could continue to develop the plan.

    The assignment of the grant included one important condition: the building should be realized by the end of 2004. This meant planning, preparing and building within a timeframe of just over one year. An important aspect in the planning was to avoid complex procedures with the city-council. Although the designated area was very tight to fit the desired program, we accepted the fact the contour of the building was determined by the boundaries of the zone.

    The care center contains a general practice, a nursing practice, an office voor babies, and a number of multi-functional spaces to be used for meetings or consulting other healthcare facilities. A striking element of flexibility is the huge door that opens, depending on the desired use.

    The center has an internal connection with the Retirement Havenlicht, so the residents do not have to go outdoor to visit the surgery.

  • Residential Care Facility “De Schutse”, Rotterdam

    Many care homes close. De Drie Nootenboomen, known for the successful Thomashuizen and Herbergier formulas, developed a new housing concept for seniors together with housing cooperative SOR. "De Zorgbutler" is a residential facility where self-employed older people can retain control of their own lives for as long as possible. Healthcare is always within reach, is characterized by its small scale and is organized and facilitated by healthcare entrepreneurs.

    The De Schutse residential care center has been transformed for this concept. In the apartment building from the 1960s, 123 independent and affordable apartments for the elderly have been realized. There are three basic types and there is a common living room on each floor. In the plinth there are 15 apartments for "Thomas in Rooms". Here people with a mild mental disability live independently under the watchful eye of a care entrepreneur who acts as a counselor, landlady and care provider in one.

    De Schutse continues as "the Pietje Bell house" and has been given a contemporary look. Original qualities have been placed in a new context. The existing façade has been repainted, whereby the existing layering comes into its own better. The double height of the entrance hall opens more towards the street. The dark, dated lift hall has been transformed into a light space flooded with daylight. And in collaboration with interior designer Danielle Lahou, the common traffic areas are beautifully finished and evoke the association of a luxury hotel. The joint living rooms have been carefully furnished by the care entrepreneurs themselves. After all, they are the ultimate bearers of the plan.

  • Villa, Reeuwijk

    After purchasing their dream location on the Oudkoopsedijk in Reeuwijk, near the Reeuwijk lakes, the clients approached our office for the design of a villa with a studio and workspace. The elongated terrain offered beautiful views of the polder landscape. Placing the square main volume diagonally on the site prevented the creation of a front garden, two narrow side gardens and a back garden. The garden folds around the villa, as it were, there are no residual areas. The facades on the dyke side are closed. On the rear side and on the south side, these are designed as transparent fronts. The roof has been positioned on the square footprint in such a way that two high-ceilinged bedrooms are created on the south side, with glazed façades opening onto a balcony.

    From the villa, the view is not limited to just this property, but the entire landscape is experienced without limit. Landscape architect Annemieke Fontein from Rotterdam reinforced this idea with a well-considered landscape design. In particular, the diagonal water feature starting at the terrace in the living room builds a natural bridge with the orthogonal polder landscape.

  • Residential house on Wittenburgerweg, Wassenaar

    The house is part of a residential block of four and was built in 1926 to a design by architect P.J. Houbolt. During the major renovation, the ground floor was substantially enlarged at the rear of the house and the floors were adjusted, so that three children's bedrooms with shared bathroom were created on the second and third floors. The master bedroom on the first floor has also been enlarged and has its own bathroom.

    The entire existing rear facade with chimney has been demolished, so that a maximum expansion towards the rear became possible. The spacious kitchen on the ground floor has a level difference, which means that it is on the ground floor with the garden. On the first floor, the extra large master bedroom is adjacent to a terrace. To make the attic bedroom accessible, a small spiral staircase has been placed at the top of the stairwell. Roof lights bring daylight into the stairwell.

    By letting the small room above the entrance lapse and making a void at this location, the hall is connected to the higher landing. This has created a spacious, well-arranged stairwell. The use of roof lights and glass openings in the floor brings daylight deep into the house.

    Although the intervention is characterized by tight detailing and modern materialization, harmony with the original architecture is achieved through the use of solid wooden fronts, overhangs and profiles as existing, the state-green color scheme in the facade and oak in the interior.

  • Pakhuis Oosthavenkade, Vlaardingen

    This former warehouse on the Oosthavenkade must have been built at the end of the 19th century by Paul Kikkert and is a copy of the demolished Twin Kikkers warehouse. This warehouse was used in the recent decades as fishing equipment shop. The previous owner introduced a mezzanine of 4 to 9 meters in the middle of the building. This caused the replacement of a lot of the original wooden column construction by a steel frame. The hood is supported by a Philibert truss structure.

    Alongside proposals for the required building and structural upgrades, a design was developed to adapt the municipal heritage building for residential use.

  • ARZS, Salzburg

    When the Vonier family approached us with the request to give advice about their accommodation in Salzburg, we were immediately enthusiastic. The Rolls Royce restorers and collectors have a museum in Dornbirn, Austria with a collection of around 100 vintage cars. In Salzburg they wanted to convert their garage location into a museum where, among other things, the restoration of vintage cars would be central. Thus the original garage would still play a central role. The location that comprises a complete building block consists of a service garage with a few residential buildings next to it.

    The project must be able to be carried out in phases so that the amorphous existing building structure is taken into account when planning. The sketch design consists of an exhibition building that focuses on the boulevard on the east side. The garage and service area on the west side is accessed from the Wilhelminastrasse. In the exhibition area, three storage towers have been included that, in addition to storage, also serve as an exhibition of the historic classics. A super-fast lift picks up and brings the cars to and from the desired position. This gives the interior of the museum a dynamic character and determines the appearance of the building.

    During exploratory discussion with the municipality of Salzburg, the need arose to first of all make a vision for integration into the “Bahnhof Nord” master plan.

    Between the new Bloemcampschool to the Bloemcamplaan and the cottages to the whites often dual citizen road in Wassenaar is a rectangular location available for a small detached villa. In 2014, created a design that effortlessly adds in the multitude of villa-typologies which are characteristic of this district.

    The vertrappende orthogonal block fits within the given contour of the built-up area which is laid down in the zoning plan. On the Southeast side is a 2 meter high wall the secretion to the adjacent school and on the street offers an electric gate access to the plot. In the zone between the wall and the crop-growing area of 4.2 meters wide is the entrance. The property consists of two layers and a basement. On ground floor are the entrance hall with staircase, living room and kitchen with orientation on the surrounding garden. On the floor are the bedrooms connected by a spacious landing. In the central reservation is the flat roof lifted up to 3.5 meters. On the highest dakstrook are PV panels. The technical installations are located in the basement, laundry room, storage and a hobby room. The cellar is accessed from the entrance hall but also has an outdoor staircase and direct access to the outside. The ground floor has a small overhang locally.

    The home is equipped with an electric heat pump with bottom changer. The heat is on the lounge issued by underfloor heating. There is a mechanical supply and exhaust ventilation system equipped with balanced (Climalevel) with heat recovery (WTW).

    The basement and the ground floor are executed in concrete, masonry walls carry the concrete upper floor. The floor is built in timber framed with flat roofs from wood joists.

    A multitude of window openings and doors are included in the full planked facade. This is a so-called open planking applied which in a fixed size system boards with small vertical open seams. The type of wood used is Middle European Douglas. The planks and slats with a semi-transparent light gray coating finished. It is in some places stripping for the glass surfaces continued in the form of standing slats. This allows the light accession, viewing and plenty of sunshine are taught. The aluminum doors and Windows are recessed in the facade and have a dark gray metallic coating.

  • Student Housing Prinsengrachthofje, Den Haag

    The Hague has 115 courtyards, many of which are on the list of monuments. The Prinsengrachthofje is an exploitation court from the 19th century. When Arcade People and Living took over the courtyard from the municipality, it was in neglected condition and the wooden foundation turned out to be seriously damaged; a thorough approach was needed for the rescue. At the beginning of 2007, Arcade approached our office for a feasibility study into possible types of homes in the outdated lower and upper homes. This resulted in 21 student apartments: 10 on the ground floor and 11 upstairs apartments, one of which is a video apartment located above the joint bicycle shed. By turning the stairs 180 degrees, both functional and spatial, efficient and compact homes were created that could be reached with a "normal" staircase.

    The contact with Monument Care from the initial phase has led to a long-term and fruitful collaboration, in which also the complications that fire safety (new construction requirements) entailed were dealt with. In the autumn of 2009, a start was made on the overall renovation and restoration. The demolition of the rear facades, the roofs and the ground floor gave the complex the appearance of a ruin for a long time. The houses have since been rebuilt with great care and expertise. We can safely say that the best student residences in The Hague were delivered by the end of 2010.

  • Reconstruction Mercatorplein, Amsterdam

    The Mercatorplein, built in the twenties of the 19th century, comes from the drawing table of H.P. Berlage. Among other things, he designed the "sister blocks" on the north and south walls, which, with their tower and gatehouse, form the urban closure of the axes of the Hoofdweg. Due to the dilapidated state, the north wall tower was demolished in 1961 and reconstructed to its original state within the Mercatorplein and surrounding area urban renewal plan of 1993.

    Housing association Het Oosten employs architect Wytze Patijn for the rebuilding. In collaboration with MATH, a reconstruction plan is being designed for 24 owner-occupied homes, 9 business premises and a catering establishment. 21 storey apartments and 1 maisonette are housed on the floors and 2 houses stacked in the tower.

    The gatehouse will be given a catering destination, acoustically separated from all surrounding buildings. Behind the restaurant on the 3rd floor is a winter garden with a sliding, transparent roof. A large glass elevator connects the floors and provides extra light to the bottom of the gate zone, where the main entrance of the houses is also located. By applying a lot of glass at that location, "social control" is possible, with the purpose of discouraging vandalism. The facades have been fully restored, including the replacement of the original tuff ornaments, the syenite plinth and the fluted tower.

    Behind the facades, the interior spaces blend into the original windows. This continues to the inner area, where the volumes are finished with stucco facades. The houses are characterized by a spacious entrance and often have a "circular circuit". The roof terrace on top of the highest house gives a wide view over Amsterdam.

  • Police Station Allegonda Gremmer, Rotterdam

    This police station was built in 1956 and is considered to be an interesting example of architecture after WW II. The original design was made by L. Voskuil, city architect of Rotterdam. After renovation, which was completed in 2002, the original building together with the expansion makes a new harmonious complex. It serves as a backup facility for the police station on Marconiplein.

    Dutch architect Wytze Patijn invited our office to develop the plan under his supervision. In the interior desing the existing building is still very much recognizable, by ways of materialization. The original facade, with its characteristic two-story loggia was maintained.

    On several places the ground floor is also two-story high, to support the spatial effect. This resulted in a central “meeting place”. A two-story high glass facade and walkways connect the original and new part of the building and make the patio a central meeting place.

    We were responsible for the architectural design, overall project coordination, and construction supervision during the project.

  • Apartments Kanaalstraat, Amsterdam

    This special building in Amsterdam's Overtoombuurt was in poor condition at the time of purchase. Foundation, floors and facades had to be thoroughly renovated. The rental apartments were completely worn out.

    The building has been split, so that the three apartments, including installations, have been completely renovated. The classic stairwell has been preserved, but the building has been given a new foundation and ground floor. The storey floors have been upgraded, which means that they meet the current requirements for fire and noise protection. The apartment on the ground floor has been extended at the rear and the roof for the upper apartment has been made accessible. From the terrace you have a beautiful view of the city.

    The façade, with a monument’s status, has been carefully restored. New vertical sash windows have just been made and placed in the existing shadow frames without making any additions to the monumental statue.

  • Radex Innovation Centre, Delft

    The Delft entrepreneur Alfons Hülsenbeck took the initiative to set up an incubation center (for start-ups) for young graduate companies at TU Delft, in collaboration with the municipality of Delft. The municipality wanted to profile itself as a 'knowledge city' and wanted to link high-quality technology with high-quality employment, thus, RADEX was established. This endeavour was successful & the center was festively opened in 1992. The center received overwhelming numbers of applications from aspiring entrepreneurs, so much so that many had to be referred to a waiting list.

    Having already done studies for expansion in 1996, we were commissioned in 1998 for the design of phase II. Although the project in its conception stages was somewhat delayed, construction started in 2002. Phase II was completed in July 2003.

    By connecting with the first phase in materials, detailing and color scheme, a conscious effort was made for a uniform expression from the whole complex, i.e. one in which the different construction phases can only be recognised when "zooming in". The success of this method also led to later developments in the nearby area, such as the Delftech park and the 'Technopolis' being developed.

    Phase III concerns the design of a large canteen space on the roof of Radex I.

  • Coolhavengebouw, Rotterdam

    Stadswonen is busy upgrading a number of student complexes. The entrance and the underpass of the Coolhaven student house are unpleasant spaces in 2016. Based on a number of wishes of the residents, the design combines transparency, color and atmosphere with a functional use of materials.

    Glass, acoustic panels with oak veneer, light colors on the walls and sophisticated lighting have transformed the entrance hall from an unpleasant dark space into a contemporary, light and warm entrance hall. The large mirror above the post boxes visually broadens the narrow entrance and reflects the wall with painted contour lines of Rotterdam. In the underpass, both the ceiling and walls are partially covered with bankirai shelves and good lighting. The home entrances stand out because of the fresh green color, the containers hidden behind perforated steel screens. The underpass is closed off by a new fence that includes the building name.

    At the end of the construction, when the coarse nameplate is removed, it becomes clear why it is so over-dimensioned: it has for years concealed the original "van de anger hardware". I.p.v. to disguise the past of the building again, we have opted for the effect of masking. At first glance one only sees "student house Coolhaven" in loose letters on the facade. But if you look more closely, you can see the history of the building vaguely shine through.

  • Kalkhoven Residence, Handel

    In 2010, a start was made on the design for the expansion of the Handelia family hotel in Handel, in this small-scale pilgrimage site in North Brabant. After purchasing a site on the north side, it became possible to move access from the hotel to the rear area and to combine it with a spacious parking facility, a storage building and a property for the manager.

    These three components are designed in conjunction with the white-painted existing characteristic hotel. Adjacent to the existing building volumes, saddle roofs were chosen, so that the building ensemble merges with the village architecture. A contrasting brown-gray masonry was deliberately chosen, creating a dynamic color and material palette.

    The house on the easternmost part of the site connects to the subdivision of the residential area Kalkhoven. The house is designed in such a way that the living areas have sufficient privacy with respect to the hotel garden, but that view and control of the hotel remain possible. The living areas are placed as an L-shape around the private garden on the ground floor. The bedrooms are all on the floor under the 45-degree roof. An open staircase has been placed in the center of the house, which extends to the top. Multiple sliding panels offer the possibility to connect living spaces together.

    The residence features underfloor heating supplied by a heat pump installation, which is connected to a geothermal energy system and an energy-generating roof. Electrical power is produced by 16 m² of photovoltaic panels located on the flat roof.
