The story of a successful transformation


A former office building located at 20 Avenue Louis-Aubert, Au20 has been completely redesigned to become a residential complex comprising 120 apartments, one exceptional penthouse and one commercial space that has already been allocated.

Each apartment, ranging from 3 to 5 rooms, offers generous volumes, large bay windows and loggias, combining comfort, elegance and brightness.

The project has been a great success, with all units quickly allocated, highlighting the attractiveness and quality of this development.

The 147 m² penthouse, extended by a 136 m² terrace, stands out for its generous spaces and spectacular views of the city and Mont Salève, illustrating the unique character of this development.

Au20 perfectly illustrates the company's ability to transform an existing building into a contemporary, functional and high-end residential complex, offering a privileged living environment for its residents.
