The RATP maintenance workshops are located on a 2.3 - hectare enclosed site. There are few facades overlooking the neighboring streets and the site is part of a very large urban block.

We are in charge of the urban project for this site. The chief aim of the project is to keep the industrial activities within the crowded city ; to open up the site ; to reorganize the industrial activities and to add value to the plot by building housing.
To do so we created a new street, placed 2 out of 3 apartment buildings above the industrial building and developed 21,000m² of housing.

The workshops encompass 11,000m² of floor space divided into two distinct buildings connected by a core of vertical circulation areas. The engineering workshops and the mobile storage systems are located on the ground floor along the new street. This part forms a base over which is located a residential building designed by Swiss architects Christ & Gantenbein. The upper part of the workshop facade is fully glazed to open a view onto the 3,800m² workshop ceiling. The perception of the large dimension specific to industry is thus ensured from the public space. The lower part of the facade is covered in enameled ceramic panels. It incorporates the three lobbies of the residential building and the entrance to the industrial site.

The ’industrial hotel’ is built over the railroad tracks, set back from the street. It is a massive structure that bears very important loads. The facades are largely glazed with outside gangways underscoring the lines of the building.
