The conversion and extension of the former Citroën garage – originally completed in 1951 to a design by architects Suter & Suter – makes reference with its towers of additional storeys to the neighbouring high-rise blocks of Zurich’s Heiligfeld housing estate, which was also built in the same decade.

The project to convert the building into a residential complex for high-density city living creates a new urban design landmark, without renouncing the building’s past.
