Office building Schader

The office building of Zurich Insurance Company Ltd on General Guisan Quai in Zurich received a comprehensive revitalisation by PORR SUISSE AG. The historic office building, designed by architect Jacques Schader, was completed in 1973. The aim of the revitalisation was to take account of the listed building fabric and to develop it further with modern elements.

For this purpose, the building was deconstructed down to the supporting structure. PORR renovated listed parts such as the facade, floor coverings in the foyer on the ground floor and in the surrounding area, as well as the plant troughs in the outdoor area, in accordance with the requirements of the monument preservation authorities.

In course of the facade renovation, all sheet-metal cladding of the listed aluminium facade was dismantled, cleaned of pollutants, and stored on site before the demolition work began. In the course of the facade installation, the sheets were reassembled in the same place by the PORR subsidiary Alu Sommer Suisse AG. The windows were modernised to meet today's requirements.

The building will be certified to LEED Gold (LEEDv4 Core & Shell) and Minergie (Standard).
