Block T10 is a mixed-use development in the Paris Seine Rive Gauche district that reconnects the southern 13th arrondissement with the Seine and the historic city. Composed of three distinct yet unified buildings, it combines housing, offices and commercial spaces within a permeable, green urban ensemble that enhances light, views and everyday life.
A central ambition of the Paris Seine Rive Gauche development is to re-establish a strong physical and visual link between the southern part of the 13th arrondissement and the banks of the Seine. Within this framework, Block T10 occupies a highly strategic position at the edge of the ZAC, directly connecting the new district to Paris’s historic urban fabric and closing the long promenade alongside Halle Freyssinet.
Beyond its urban role, the project reflects the City of Paris’s broader vision for a more humane, open and sustainable city — one that embraces light, air and greenery, encourages walking and cycling, and offers generous shared spaces for everyday life. Paris Habitat and ICF Habitat Novedis initiated an ambitious mixed-use competition for this site, bringing together family housing, student residences, homes for middle-income households, SNCF offices, commercial spaces and an underground public car park. The competition was won by SeARCH, in collaboration with Atelier Phileas and LA Architectures.
One project, three architects, three buildings: each building has its own architectural identity and program, yet they are unified by shared principles. Rather than acting as a barrier, Block T10 is conceived as a permeable urban element. A fragmented skyline creates openings for views, sunlight and ventilation; façades express domesticity at close range while contributing to a strong urban presence from afar; and a continuous green ribbon ensures that nature is visible and accessible throughout, with trees, planted terraces and shared gardens woven into the architecture.
Block T10 is a place where landscape, architecture and public space comes together to reinforce connections across the city and support a vibrant, liveable Paris.
