Porte de Saint-Ouen

31 avenue de la Porte de Saint-Ouen 75017 Paris

The “Porte de Saint-Ouen” site is part of the Innovation Arc, an urban and social laboratory for innovation. The approach to handling a gateway between Paris and its suburbs is a major issue for the Metropolitan Area. This Parisian property of over 4,300m² (firm tranche and optional tranche) is a key site in Paris’ green belt. The development projects underway in the surrounding gates and muncipalities represent promises of renewed attractiveness for this interface territory, which will have the mission of offering solutions for new urban uses.

Current use

P1 (firm tranche) freed up by the demolition of a housing block
P2 (optional tranche) used by a service station and a car park conceded until 2021, recovery possible

Planned programme

P1: open programme, must integrate the access road to the TRAM
P2: open programme


P1: Paris Habitat, planned acquisition by the City of Paris

Planned nature of the transferred rights


Urban context / existing buildings

This Parisian site is located along the municipal boundary with Saint Ouen, right near the Bichat Hospital, one of Paris' major university hospitals. Avenue de la Porte de Saint-Ouen, which provides access to the site, is in reality part of a longer avenue that stretches several kilometres, connecting Place de Clichy in Paris with Place de la République, where the Saint-Ouen Council Building is located.
This gate, a vestige of Paris' fortified walls, demolished in 1919, is today one of the major sites on Paris' green belt, with the Max Rousié Stadium to the west and Square Henri Huchard to the east.
This site is well served by public transport, Metro line 13 (Porte de Saint Ouen station) and two bus lines: line 81 connects the site to the centre of Paris and line 341 connects it to Clichy and Saint Ouen. The Traverse 518 bus line also connects Batignolles and Bichat, and the PC line, which will be replaced at the end of 2018 by tramway T3, will increase access to the site.
Neighbouring the ring road, this site benefits from direct road access to the Ile-de-France motorway network.
This interface between Paris and its neighbours has long been a deprived and isolated area, used for social housing buildings, which are now partially demolished. The goal is now to make this area attractive and, in order to do so, remove the urban barriers that have been created.

Prospects for innovation

Innovation for uses, in the construction arrangements, protective solutions from disturbances from the ring road, sustainable development
