The Lem + agency hands over 44 social housing units in Marnes-la-Coquette on a protected block lying between the SNCF main line station and the A13 motorway.

Located on the edge of the Saint-Cloud national park, the project by architects Pierre Lépinay and Bertrand Meurice for the I3F social housing development group is set in a particularly green area enclosed by the Garches- Marnes railway station and the A13 motorway. Comprising
single-family homes with private gardens on the railway station side and by a group of apartments provided with balconies and ranging from studio flats to four
and five room duplex units, the operation (3,338 m² net plan area) takes the form of a drawn-out U-shape that protects the centre of the block from the noise nuisances
resulting from the presence of the motorway to the south. These housing units with their large number of windows and dual aspects are particularly bright. The private gardens are bathed in sunlight throughout most of the day thanks to roof profiles specifically designed to limit shadow impact.

The architects provided a number
of innovative solutions to overcome the noise constraints. In addition to the protective
U-shaped layout, they incorporated a wooden

fence running alongside the
motorway, built two-storey buildings with reinforced insulation in the attic
spaces, installed sloped roofs with a continuous nine metre high ridge line, and equipped the
housing units on the motorway side with acoustic loggias.

Acting as a green extension to
the housing units, the acoustic loggias open the apartments onto the south, providing
large glazed spaces giving onto the Saint Cloud park while also protecting
residents from noise.

This planted space, opening onto
the sky and closed off to the sides by glass screens, forms a particularly efficient
acoustic barrier that is further reinforced by the

specific layout of the
apartments. The utility rooms give onto the motorway side while the main rooms
open onto balconies, loggias and private gardens on the protected

side. The noise nuisances are
also reduced by the use of a double flow system that avoids the creation of
acoustic bridges, improves air quality and contributes to heating

the housing units.

Wishing to adopt energy-saving
solutions, the architects chose to use interior insulation with thermal breaks
on slab nosings, install solar panels on the roof and equip

each housing unit with solar
collector tanks. They also paid particular attention to the landscaping
project.

Climbing plants have been placed
around the site to colonise the fence on the railway line side and the 150 metre
long support wall on the motorway side. Lying in

the heart of the block outlined
by the U-shaped layout, the private gardens are reduced in size as much as possible
to offer larger spaces to the common areas that are planted with a variety of
species and looked after by the landlord.

This housing project has seen the
LEM + architects invent an alternative type of landscape that contributes to
the well-being of the residents. Recently handed over, over half of the
housing units are already occupied.
