ABSTRACT
Introduction This building is a district agency for SUVA, which is the Swiss equivalent of the UK National Insurance Service, but privately operated. The original six-storey building had been constructed in the 1950s and was typical of the period, with a regular arrangement of hole-in-the-wall windows and sandstone cladding. The architects were commissioned to overclad the existing building and improve its thermal and lighting performance. The existing sandstone façade remains intact behind a new glazed skin set 100mm in front of the original.
