Extension and Refurbishment of a Residential Tower Weberstrasse

Burkhalter Sumi Architekten as Architects

An extension over the full height and width of the rear facade is planned for an existing 12-storey residential tower by Architect H. Isler (dated 1960). The permitted exploitation of the site is utilized by adding a vertical extension to the tower rather then constructing a separate building. The existing north facade is refurbished by the extension and the external space with the beautiful trees retained.


The four existing small flats will be merged into two large family flats. The newly built extension will be occupied by small and duplex flats which relate to Le Corbusier’s section of the duplex flats of the Unité d’ Habitation. As the new flats are accessed from the intermediate landings of the existing staircase, the „rue intérieur“as reference is omitted.


The newly rendered facade connects the existing tower with the new extension. The facade with the bedroom windows is alienated by using different colours to differentiate between horizontal and vertical facade elements. An image of a mesh structure is created. To make the balconies more private 12 storey high textiles printed with floral patterns are fixed to the balconies. These elements introduce a new large dimension to the facade.
