Kindergarten "La Ruche " in Perthes, Gâtinais

URBANISM AND ARCHITECTURE

In the small village of Perthes-en-Gâtinais in the south of the Seine and Marne (77), the plot of the project is a wooded and pedestrian site in the heart of historic village.

The city is accompanied by the PNRGF (Regional Natural Park of Gâtinais Français) for environmental ambitions; The choice of construction Dry Filing is most relevant and more respectful of its environment close and global, the project is then built in wood frame and wood cladding For a record building time (10 months) and a nuisance of construction site (site inhabited by an existing nursery school).

Its linear layout has freed up a maximum of free and vegetal footprint in continuity with the pedestrian mall and kindergarten and primary playgrounds. This new, more visually generous space reinforces the bucolic and intimate nature of the undergrowth into which the new equipment is inserted. Coming "to live" in this park provides the opportunity to continue its inscription in the history of the city and to offer a generous space, and appropriable for all Perthois and their children.

The general volumetry of the project borrows from the historic town center, its archetypal and typical volumetrics; houses in the town of Perthes, consisting of dense low-rise housing that has been built and densified, year after year. She reinterprets their iconic profile to draw an appropriable symbol.

LANDSCAPE

The courtyard is composed of a large mineral space in the extension of the yard. Peripheral areas are covered with chips called BRF, for the comfort of children and improving the living conditions of trees. The schoolyard is thus a real undergrowth with soft ground and hard ground. Some trees are planted to allow a progressive renewal of afforestation.

Located at the back of the school, the educational garden is composed of elevated garden bins for the youngest and open spaces. A valley of rainwater harvesting also creates a favorable environment for the development of biodiversity.

Architectural description

The general volumetry of the project borrows from the historic town center, its archetypal and typical volumetrics; houses in the town of Perthes, consisting of dense low-rise housing that has been built and densified, year after year. She reinterprets their iconic profile to draw an appropriable symbol.

The new nursery school is set up on the same level, and in linear, which allows to create, volumetric identities distinct by space, with variable widths and heights by program. Inside, these capable volumes offer a particular and generous spatiality to the premises. teaching. These volumes are very generously glazed on the playgrounds and in the backdrop of the wooded mall.

All indoor spaces, designed with the ladder of early childhood as a major reference, are lulled by natural light, in bright, bright and warm spaces.

The stick siding, which follows the slope line of a 45 ° roof, draws a house like a child could do, simple, iconic, graphic. The symbols of the gables of the classrooms are found inside for the signage and orientation of the children

Comfort

Health & comfort :

Implantation - By its major orientation to the east direct light in the classrooms are optimal (only in the morning) and have in addition to the large glazed elements in roofs oriented South and domotized (closing of blinds and openings of the glazed parts) allow users to choose their need for complementary natural light. the whole forming a living environment generously open to the outside without overheating possible. A child-scale building - All interior spaces have been designed with the children's ladder as a major referent, furniture, access, lightening height. the volumes of life proposes heights under ridge which can go according to the programs up to 6 meters. Visual Comfort - With its wooded frame the views from inside the building is of great quality is made by large openings in wood joinery for sitting children. The heating (whose needs are very low in view of the airtightness and the important insulation) is done by low temperature radiant panels

Acoustic comfort :

Indoor Acoustics - All project ceilings are sound absorbing panels. each interior volume of the program being two-sided, the absorbing surface proposed is twice as high as a "flat" ceiling, this material composed mainly of agglomerated wood fiber has also been chosen for their very high performance (alphaW = 1)

Exterior Acoustics - Since the project site is already very qualitative from a sound point of view (only pedestrian and at a great distance from the roads), the outdoor areas in addition to their geometry deconstruct the sound, also have an absorbent acoustic behind openwork cladding to reduce nuisances during recess

Reasons for participating in the competition(s)

La nouvelle école maternelle s’implante de plain-pied, et en linéaire, ce qui permet de créer, des identités volumétriques distinctes par espace, aux largeurs et hauteurs variables par programme. Coté intérieur ces volumes capables offrent une spatialité particulière et généreuse aux locaux d’enseignement. Ces volumes sont très généreusement vitrés sur les cours de récréations et en fond de décor le mail boisé.

L’ensemble des espaces intérieurs, conçus avec l'échelle de la petite enfance comme référent majeur, sont bercé de lumière naturelle, dans des espaces clairs, lumineux et chaleureux.

Le bardage à bâton rompus, qui suit la ligne de pente d'une toiture à 45°, dessine une maison comme un enfant pourrait le faire, simple, iconique, graphique. Les symboles des pignons des salles de classes se retrouvent à l’intérieur pour la signalétique et l’orientation des enfants
