Ambassador House, Opfikon

Following its total refurbishment, Ambassador House in the Glattpark, Opfikon, will be a commercial complex with the largest interconnected floor area in Switzerland. After completion, the building will have seven floors with a total usable area totalling 57,000 sq.m. Apart from the building's exterior, the refurbishment will also include technical and energy-efficient features. One of the major challenges faced during the preliminary phase is the demolition of the 22-metre-high building technology floors above the seventh storey.
