Train maintenance workshops for metro line 12 are located on a 2.3 hectare site, which is enclaved : it is part of very large urban block and it offers little or no view of the surrounding streets.We are in charge of the urban redevelopment of the site. The chief aim of the project is to connect the site to the urban fabric, to reorganize the industrial activities and to add value by the construction of housing buildings.
A new Parisian street and a pedestrian passage are created.
The new workshops are spread over 13,000m² of floor space divided into two separate buildings linked by a vertical core.
- On the ground floor alongside the new street there are mechanical workshops and mobile storage systems. This part forms a base, which is surmounted by a residential building designed by the Swiss architects Christ & Ganterbein.
The upper part of the façade on the street is entirely glazed so as to clear the view over the 3.800m² of workshops ceiling, whose architectural treatment will be carefully detailed. In this way the industrial dimension will be perceived from the street. The lower part of the facade is regulated by a pattern of vertical stripes that runs across the full length of the base. This system allows to integrate and at the same time differentiate the three halls of the apartment building and the RATP lobby.
- Set back from the street, built above railway tracks is the industrial workshop, a massive structure supporting heavy loads. The facades are fully glazed. Walkways underline the horizontality of the construction.
