The challenges 

The Balexert shopping center consists of three buildings constructed at different times (built in 1971 and expanded in 2001 and 2010). The renovation project "RELOOKING Balexert" aimed to unify the center (about 14,000 m2) and to update the technical systems and equipment of the buildings. The work was carried out in 14 stages, from October 2018 to September 2021, in a facility in continuous operation.
