Modernization of the Haliotis STEP, Nice

In the exceptional site of the Baie des Anges, in the French
Riviera, the renovation of the Nice sewage treatment plant
will allow to rebuild in situ the equipment that will continue
to work during the works. Its urban and landscape integration
will be promoted through landscaping (52% of the land
right will be landscaped) and the formation of a planted
relief, Cap Haliotis, which wraps around the industrial site
and gradates its plantations from the monumental urban
entrance to the coast.

The site plan proposes a stratification of buildings, from the city to the sea: the facade on the Promenade des Anglais is perfectly integrated into the city, in continuity with the landscape, a serving strip then hosts the storage and process areas, and finally the process area, on the seafront, completely integrated. The architecture of the factory will be in harmony with the city, staged by its green spaces, and dressed in noble materials (stone, terracotta). Inspired by the Haliotis shell, it offers a gradient of shades of its facades, which go from red ochre in urban facade to white ochre near the sea.

Reminiscent of the diving board in Nice, a lookout allows an educational discovery at 360° of the site. The environmental aspect of the project is also very ambitious: the STEP will become a positive energy plant, combining global energy optimization and energy recovery.
