The identity of this historic site will be preserved, among other things, by means of valuable listed halls and generousopen spaces. Three new high-rise buildings with heights of 35 m, 50 m and up to 100 m are also being built, as well as unique townhouses that reinterpretthe town house typology of the old town.


According to the design plan, a total floor area (aGF) of 34’500m2can be realized on site4b. The “Tigerli” base building comprises 17’500m2(aGF) space and may reach a maximum total height of 23 meters. A further 17’000m2(aGF)and a total height of max. 100 m are available for the construction of the “Rocket” high-rise building. The masterplan allows a residential share of 100 %.

In the “Rocket” high-rise residential building, a large number of differentrental apartments are planned in order to address as many target groups as possible in the greater Winterthur area. The “Tigerli” base building will contain non-profit housing witha focus on large and communicative family apartments.
