In the heart of Rueil-Malmaison, we are transforming five office buildings previously occupied by Suez into a residential complex with 149 flats, a 179-seat auditorium and a 100 m² retail unit.

A major conversion of offices into housing in the Greater Paris residential area 

On the edge of Paris, in the Hauts de Seine department, Rueil-Malmaison has the charm of a provincial town just a stone’s throw from La Défense. Its lifestyle around the Château de la Malmaison and its accessibility make it a highly sought-after town. The renovation of a building previously occupied by Suez in the centre of the town will further enhance its appeal.

Project history

Built in the 1960s, the building was home for many years to Degrémont (a subsidiary of Suez) specialising in water treatment and distribution.
The complex comprises several buildings arranged around an inner courtyard, ending in an industrial-style red brick building. Following the merger of Degrémont with Suez, a second project to transform this complex was drawn up in 1988 by the architect “Jean-Paul Viguier et Associés”, who decided to keep the brick building and raise it with a bridge-like structure.
Today, and in the context of the departure of Suez, a new project has been initiated by Covivio with the assistance of “VIGUIER, Architecture Urbanisme et Paysage”. This aims to transform this service sector building into a residential complex.

Rehabilitating and desartificialising

The guiding principle of the project is to create more housing with less floor space and to offer green spaces and shops.

With a view to urban recycling, the demolition work is limited to recomposing the facade to create access routes (staircases and lobbies) and private outdoor spaces. The project involves raising the building by one or two storeys, using bio-sourced materials such as wood to create generous green terraces and panoramic rooftops.

This residential development also includes the creation of a 100 m retail space2 and the renovation of the existing auditorium into a public space, a cultural space for creation, meeting and sharing, thus contributing to the liveliness of the ground floor, open to its surroundings.

A sustainable and responsible project

In addition to complying with the new RE2020 regulations, the project is part of a strong environmental approach with a limited carbon impact, in particular through the conservation of a large part of the building and the reuse of ashlar from the existing façade to clad the future building lobbies.

Urban recycling

Located in the heart of Rueil-Malmaison, this 14,000m² project is the result of the renovation of a building occupied by Suez.

Reuse of materials

In an effort to limit the project's carbon footprint, materials from the deconstruction work are being reused, such as the ashlar from the existing façade, which will be used to clad the future building lobbies.

Opening up to the city

A retail space and an auditorium for a lively ground floor designed as a meeting place open to its surroundings.
