Design of a green, mixed-use development in a rapidly changing neighbourhood.

In the heart of the Quai St Serge ZAC, a mixed urban development zone that is undergoing major changes, our team is designing a mixed-use programme for Angers Loire Habitat, consisting of four buildings, one of which is nine stories high.
This building development consists of 3,500 square metres of office space, 170 student housing units for CROUS, the Centre Regional des Oeuvres Universitaires et Scolaires (a government agency that offers a range of social services to students), 30 units for social social housing in the nine-storey building, 14 housing units and more than 150 square metres of space for businesses to use.
Served by tram and linked by a network of pedestrian routes and streets, the proposed plot offers a great opportunity to develop a comprehensive and ambitious urban project in keeping with those already in place.
We have developed an urban design that facilitates encounters and social interaction. Despite the requisite high density of the project, the different buildings are articulated in response to the surrounding buildings.
We wanted to introduce landscaping into the heart of the development and to have views and openings, both visual and for pedestrians, through the plot in order to ensure the continuity of the main sight lines introduced by the urban planner. The project encourages activity at ground level on the street side.
