Owner approach of sustainability

The client was determined to build the entire structural work in CLT (Cross laminated timber) which allowed the designer to propose to use the structural work as finishing materials for interior facades and ceilings in each dwelling. This economic gain is also environmentally friendly for reducing the amount of materials used in the construction site.

Architectural description

The entrance to the building is on the side of the street de la Perle, and takes advantage of the release of the Street du Niveau to improve its readability.

It is fully open to the outside and protected from the wind, naturally lit and gives a bird's eye view of the common garden. The entrance to the ground floor dwellings is developed on the side of the garden. This space is equipped with benches, low plantings in front of the rear facade, shrubs and covered and secure bike parking.

The common area of the ground floor, has a storage for strollers and bicycles, directly accessible from the entrance. The circulation spaces and access to the apartments are sized to create places of conviviality. The common areas are all located on the ground floor of the building.

The program consists of 4 studios, including 1 adapted for disabled people, 3 1 bedroom apartments and 11 duplex 4 bedrooms. 17 apartments have their outdoor patio area. All accommodations are crossing. The terraces are developed on the south / east side of the project, their easy use will participate in the life of the rue de la Perle and rue du Cinéma. Each housing has a storage space and technical room. The duplexes also benefit from another storage space arranged along the night hall.

The net living areas of the living rooms, dining room and kitchens are increased in relation to the minimum necessary requirements according to the number of rooms. The habitability of the dwellings is by this principle also increased. The circulations of the dwellings are optimized to dedicate more space to the living rooms and mainly to the stay which receives the whole family.

Water management

Indoor Air quality

• Indoor Air quality :

  The hygienic air is continuously supplied in the housing by the ventilation system with double flow. Air filters purify any polluting particles contained in the air brought. They are changing once a year.

Health & Comfort

• Health & comfort :

  The hygrometry of the building is self-regulating by structural elements in CLT wood of the building left voluntarily visible. The wood absorbs the water contained in the air if the percentage exceeds the average rate. Conversely, in a drier period, the wood will return the water into the housing atmosphere.

• Acoustic comfort :

  The following elements provide good acoustic comfort to housing: -The building is equipped with triple glazing.-Excellent airtightness of the envelope.-High performance insulation. 22cm of mineral wool.-Wood absorbs airborne noise better than traditional finishing.
