The development was inspired by the spatial concept of the loft and the pragmatic qualities of industrial architecture. The building is based on a simple module comprising two cubic elements, one set horizontally, the other vertically. Twelve different interlocking modules stacked in various ways create a structure with a clear form and allow a maximum exploitation of the site. The modules can be simply joined ­together to create different spatial sequences. The building has a reinforced concrete cross-wall structure with pile foundations. Internally, the spaces are distinguished by exposed ­concrete walls and soffits, with solid oak ­boarding to the floors. The high rooms and the absence of partitions provide the occupants with scope to influence the internal ­architecture. A gallery level can be inserted in the two-storey zones, for example. Similarly, all necessary service shafts were constructed, but the sanitary installation itself was left to the users. Most of the dwellings are reached via a projecting access balcony with large planting troughs. These and the planted roof compensate for the completely sealed ground area that was necessitated by the contamination of the site during its former industrial use. The access structure is cantilevered from the building. All loads are borne and transmitted to the main structure by two vertical reinforced concrete walls and the balcony slabs themselves. The foot of the single-flight concrete staircase is connected to the foundations by means of a tension member.
