Designed by Atelier Zündel Cristea for Bouygues Immobilier, this mixed-use complex of housing, offices, and commercial space is located on Terrasse 9. It is divided into two distinct parts:

• an L-shaped building made of glazed bricks, inspired by New York terrace apartments;
• three buildings set on the base, composed of double-height terraces that will feature various plantings.

Covering 11,477 m², this program includes:

• 147 housing units (9,716 m²), including 88 open market units, 26 subsidized units, and 33 PLUS social housing units managed by the OMHLM;
• A municipal public facility: social and cultural center (894 m²)
• A business center, offering office space at attractive prices for SMEs or for the occasional needs of large companies based in the area (867 m²)

Green Home is a BEPOS-certified program. It is unique in that it produces more energy than it consumes for housing thanks to innovative techniques:

• Apartments are oriented to maximize sunlight exposure.
• Electricity is generated by 525 m² of photovoltaic panels installed on the roof, and the residence produces energy that is sold back to EDF.
• Significant insulation is provided by triple glazing.
• Recovery of grey water from the apartments (showers, bathtubs, etc.) converted into hot water using a heat pump.

Green Home is certified Habitat et Environnement (Habitat and Environment) and has obtained the BBC 2005 Effinergie label, standards required by Paris La Défense, developer of the Espace Défense Seine Arche.

The building has been specifically designed to minimize noise and vibration pollution (in particular through the installation of anti-vibration breaks).

Located on the edge of Terrasse 9, opposite the Cité Administrative, close to the Provinces Françaises district and the Projet Cœur de Quartier, this mixed-use development benefits from its proximity to the Nanterre-Université RER station and the A14, A86, and RD914 motorways.

All public spaces surrounding the project will be redeveloped by Paris La Défense, including the rear promenade above the RER tunnel.

Work began in March 2014: the first stone was laid on June 6, 2014, and the building was inaugurated on June 21, 2016.
