Architecture in the sense of a building art hardly plays a role here, for marketing and spatial qualities are regarded as unimportant and superfluous.
Furthermore, social housing developments are facing great financial pressures due to a tightening of environmental laws, which entails a considerable increase in costs for technical equipment and building components, and negatively affects design opportunities.
International star-architects barely show any interest in the topic. Accordingly, very few alternatives (to standard solutions) are being produced which, by becoming showcases, could act as catalysts to break out of the recent stasis.
The Hiphouse project in Zwolle presented Atelier Kempe Thill with a welcome opportunity to fundamentally question the assignment ‘social housing’. Largely due to the client’s ambition and the active support of urban planners, a prototypical project could be realized without exceeding a typical Dutch standard budget for comparable projects. A radical minimization of architectural means and a visible assertion of the processes and technologies of the building process helped to realize a maximum of living quality.
The deck-access typology is the most common form of multi-story social housing in the Netherlands, because a large number of apartments can be connected to a limited number of stairwells. Despite the social stigma this typology has come to represent, it remains an almost inevitable solution. Due to its extreme cost-efficiency it is still being employed today in large numbers. The very compact building typology realized through the central circulation in Zwolle offers an economic and competitive alternative.
The building block, measuring 23m x 32m and providing 8 units per floor, has a very limited facade surface in relation to its floor area; this favourably affects building costs and enables the high quality detailing of the facade. The housing units are organized around a central core containing a double stair and an elevator. The plan layout allocates the larger apartments to the spatially interesting corners, thus creating apartments with double orientation.
The smaller studio apartments either face east or west, guaranteeing optimum sunlight for all apartments. To compensate for its volumetric compactness, the building’s surface is consistently glazed. Anodized aluminium profiles hold the high quality solar-protection glazing to form the facade. Depending on the viewer’s position the building appears to be covered by a transparent skin or a reflective surface; furthermore, sliding doors provide generously dimensioned facade openings.
As a whole, a very delicate visual balance is achieved. The functional grid of the windows and the underlying construction form a rigid architectural order, which is counterbalanced by a spontaneous collage of colourful apartment interiors. In a display of the complexities of city life a vital and optimistic image emerges, striking up intensive communication with the neighbourhood. This image is collective as well as individual, for it is – consciously or unconsciously – formed with the active participation of every inhabitant. The ‘building in use’ therefore essentially becomes the facade.
