The transformation of the office building into collective accommodation that a building can  have several lives. Our architectural approach architectural approach is to make as few changes as possible to the existing building necessary for the viability of the project.

Almost all of the project focuses on two additions: the extension of the built volume on the Boulevard des îles side and the creation of external walkways at the heart of the block. The range of flats comprises 10 T2, 43 T3 and 2 T4 apartments spread over seven levels. All the T3 and T4 apartments have  through or double-oriented, which encourages through-ventilation and natural lighting and  natural lighting. All the flats have generous ceiling heights from the existing offices (2.63m under false ceiling) and an outdoor space outdoor space created by the project: loggia, balcony or terrace on the ground floor.
