The Beauséjour urban development plan (ZAC)

Urban project

The Beauséjour urban development plan (ZAC)

Urban project

The neighbourhood of Beauséjour, with its sweeping views of the Indian Ocean in the north of Réunion Island, is a flagship project for sustainable towns. Destined over time to welcome more than 8,000 inhabitants in 2,300 dwellings, it represents a unique example of applying ecological development principles in a tropical environment.

The specificities of Réunion Island’s geographical context – cyclonic rain, intense heat, constraining topography and endemic ecosystems – have resulted in the design of unique public spaces. Rooted firmly in the site, they provide a quality of atmosphere essential for meeting the challenges of a town where all the amenities are accessible on foot.

The layout of public spaces, surrounded by highly urbanised areas connected to more natural zones, optimise user comfort. Designed by the agency Tekhné and Atelier LD, the urban design is built around paths formerly used for sugar cane production, which the neighbourhood is transforming.

A canopy of plants provides shade and coolness for the streets and the facades of buildings. Linear parks, along the ravines that cross the site, offer densely planted  green corridors, which reduce the effects of the heat thanks to the evapotranspiration of the vegetation.
