Designed and built between 1964 and 1970 by the architects Georges Berthoud, Georges Brera, Oscar and Claire Rufe and Paul Waltenspühl, the Tourelle development, with its 415 flats and a number of commercial premises, is built on a vast five-hectare rectangular plot overlooking the old village centre of Petit-Saconnex.
Located close to international organisations, this emblematic complex was built to meet the needs generated by the influx of international civil servants.
The flats, spread over 15 buildings, had not undergone any significant renovation. Only a minor renovation of the façades, including replacement of the glazing, was carried out between 2006 and 2010. The buildings are therefore generally in their original state.
The project involves refurbishing the flats and also restoring the roofs, façades, windows, balconies and terraces. The aim of this renovation of 415 flats on an occupied site was to provide more energy-efficient spaces while preserving the original architectural appearance and guaranteeing a high-quality living environment for the residents of La Tourelle.
The renovation will lead to Minergie and SNBS Gold certification.
