Description of the project:

The pre-world war factory workers dwellings were not designed for eternity, although charming they were in dire need of modernization. Housing cooperation ieder1 took the rigorous step of pulling down the complete quarter and starting allover again. The Hoornwerk quarter is a triangular area which is close to the Deventer city center. This part of the city has been the subject of significant change. New developments like the IJsselland College and the Social Insurance Bank are leading to a change of character. 



Between the context and the program a paradox arises: on the one hand there is a demand for a small, intimate urban environment, on the other a structure is needed for large ensembles of buildings placed in a green environment providing spacious views. KCAP has developed a structure which combines the advantages of a small-scale city-structure with that of larger object-like units. This is achieved by programming different building types, dwellings, apartments, care and grouping them around a semi-public courtyard or system of alleys. The urban plan comprises of three larger ensembles which could be compared to islands in a sea of green.

There is a concentration of building-volume on the edges of the islands making them appear larger. The islands are situated in such a way that the ‘open spaces’ in-and outside the ensembles are connected by sightlines.

The relatively dense islands are separated by broad and generous green wedges. These green spaces are car-free and consist of a high user quality. The layout has a park character and makes maximum use of height differences and play elements. The adjacent housing is orientated towards, and in some cases is accessed from, the green. The threshold between public and private green is subtly differentiated by discrete height differences.

Car parking is facilitated in semi-submerged decks, or in the case of island nr.2, underneath the dwellings. The decks have an open structure so can be considered as being exterior spaces. Exhaust fumes are ventilated naturally, there is daylight and the possibility for social control.

The elevation within the islands varies. For each island a mix of single-family houses and apartments is conceived. There is special consideration made for daylight penetration and view.
