Concept
Standing near Dijon station, Tour Sigma is an office tower designed and built in 1974 by H. Favre. The rehabilitation gives a new identity to this building, becoming a beacon marking the entrance to the city.
Program
Tour Sigma can be considered as two distinct parts: an eleven-storey tower and a two-storey neighbour organised around a central patio garden. The office tower, which no longer fulfilled the purpose it was designed for, is undergoing refurbishment to bring it up to date with current working practices. It was also seen as the opportunity to update the environmental footprint of the building with a review of its energy performance.
The new facades improve the overall transparency of the building, with an extensively-glazed main elevation making an eye-catching addition to the street. Particular attention has been paid to the visibility of the entrances, and the landscaping. Two new extensions improve the functioning of the ensemble without, in any way, modifying the silhouette of the scheme.
Benefitting from a 360-degree panorama of the surrounding area, the rejuvenated tower is a new landmark for the city.
