The project consists of the construction of a building bringing together two structures IMP and IMPro and shared common premises. The design of the project takes into account the specific nature of the type of disability of the children and adolescents received. It creates spaces that are easily identifiable and locatable by children.
Particular work has been done to reinforce the daily rhythms by creating a break thanks to the floors which strongly mark the action of going to the activity rooms or the catering, like the daily rhythm of the active in their place. of work (valuing users). At the level of the floors, Mengeot and Associates has tried to strengthen the impression of small dimensions: the premises are organized in order to reduce the linear traffic, to reduce the feeling of « establishment » and strengthen a domestic dimension – interior spaces are designed to be as “container” as possible. The circulations have recesses and widening to intersect the space. Retirement spaces will be set up in the common living rooms intended for autistic people – The rooms are mono-oriented: the exterior joinery is dimensioned precisely according to needs and sensitivity and can be partially obscured (for hypersensitive children) and made translucent ( to avoid distraction when looking at the landscape) – The acoustics of the premises are very efficient (insulation and reverberation) / a particularly important point in the daily life of autistic children – Artificial lighting is suitable (no fluorescent lamp, but LEDs) / the rooms are lit by two types of source; direct and indirect with independent control on a dimmer – The muted colors of the premises show a rich chromatic range favoring the identification of the different types of premises (bright and too light colors will be prohibited) We have made sure that each program element is easily identifiable and that the operation of the establishment is easily readable in order to promote the appropriation of the building by the children. Each structure (IMP, IMPro) will be identifiable from the inside by a dominant color.

Strong points

  • Architecture adapted to the type of disability (children and adolescents, some of whom have autism spectrum disorders)
  • Taking into account the types of routes of users – staff and people received (indoor and outdoor pedestrian routes) – Taking into account professional tasks (routes and layout of the premises) including those relating to upkeep and maintenance
  • The project is developed on five levels treated in R + 2 + attic and creation of a lower ground floor, to respect the type of volumetry of the surrounding buildings (pavilion) for a good integration into the site.
  • Location: The building is organized in an “L” shape and allows the development of a large linear façade while respecting a distance of 8 m in line with the main views facing the property lines. Although the two structures (IMP and IMPro) develop vertically, each benefits from large outdoor spaces. The common catering premises are located on the ground floor, facing south, on one level, opening onto a large terrace and landscaped outdoor spaces. This establishment makes it possible to reinforce the principle of daily organization of the children welcomed: to mark a break between the activities on the floors and that, more playful, of catering in the DRC.
  • Space flexibility: movable partitions ensuring good acoustic insulation and giving the possibility to compose a large space and to strengthen the relationships between each structure.
  • Outdoor extension of spaces onto green exteriors
  • Natural lighting of the premises with treatment of overheating and glare (sun screens)
  • Internal circulation with extra widths creating sequences
  • Each structure benefits from an identified vertical circulation


  • Insertion into the site: Work on the volume of the building identical to the surrounding buildings (suburban)
  • Bioclimatic design taking into account the orientations to define the location of the premises (common living spaces located in the south, bays equipped with architectural devices to avoid overheating) and optimize the natural lighting of the premises
  • Concrete structure to provide good thermal inertia of the building and user comfort
  • Reduction of load-bearing points to facilitate long-term partition modifications
  • Curtain facade in wood frame to ensure the treatment of thermal bridges.
  • Optimization of the size of the windows according to the orientation and the surface of the room
  • Architectural devices to avoid overheating and equipment of screen bays
  • Roof rainwater treatment by temporary retention
  • Heating provided by VRV system
  • Double flow ventilation (85% recovery)
