Overhaul of the residential complex Heumatt in Zurich-Seebach

documentation p. 1258 - 1262
Architect Primas, Urs |

The renovation of a group of apartment buildings consisting of a tower and two low-rise structures, all dating to 1970, presented the opportunity – in addition to improving the energy-efficiency and building-technology – to alter the spatial relationships in the tower’s flats. The architect considered each flat individually, taking into account, for example, the orientation and position within the building. In the lower part of the tower small flats were consolidated, creating maisonettes which offer autonomous areas for parents and children. In the upper levels of the tower, small flats were also adjoined, attaining spacious, L-shaped living-cum-dining areas; these flats contain a room with separate entrance and bathroom which can be used as teenager-room or small office.
The buildings were fitted with exterior insulation and clad with corrugated aluminium. In the upper reaches of the tower, which are more prone to the elements, the balconies were enclosed with sliding–folding windows, and serve as conservatory or as enlarged living room. In order to attain the Swiss energy-efficiency standard, the flats were equipped with controlled ventilation.
