Stampfenbachplatz - Zürich

The job of converting an old attic level into exclusive penthouse apartments required considerable skill and experience. Despite the spatial constraints and problems involved in establishing the site, Steiner's expertise ensured that the comprehensive refurbishment of the residential and commercial building was completed within a short period under full operating conditions and without decanting any residents.

The architectural challenge consisted in fitting out the attic so as to create ultramodern maisonette apartments. The architect optimised the spatial arrangement by amalgamating some of the fourth-floor units. Despite the windy wintry conditions, a temporary roof made it possible to completely renew the pitched roof structure and replace the brickwork and thermal insulation. The meticulous refurbishment – most notably, the renovation of the old parquet flooring, full modernisation of the building services systems and the exclusive interior fit-out – amounted to a significant upgrade to the property.
