New construction / conversion residential buildings Schlossbergstrasse Wädenswil, 2011

123 Residential buildings Schlossbergstrasse

Due to the merger with Horgen Hospital, Wädenswil Hospital was closed in 2005 and a new utilisation of the site was planned. The project, which emerged from a study commission, included a continuation of the concept for the Bräm brothers’ hospital building from the 1930s. Five new volumes were built on the terraced site which follow the proportions and orientation to the hospital building. The conversion of the hospital and the addition of the new buildings allow for a total of 66 apartments with 2 to 5 1/ rooms. The facade design reflects the ensemble effect intended in the siting. The materialisation of the apartments and the general areas in the former hospital reflect the zeitgeist of the time of origin, the materialisation of the new constructions resume the ones of the conversion with contemporary means. All outdoor spaces form one unit with the residential buildings, which are within walking distance and surrounded by a light grove of trees. The existing south-facing park facility is mostly preserved. Lilacs line different squares, which have sitting options and playground equipment, the view of the lake and mountains is unobstructed.
