SITE CONSRAINTS : (URBAN LOCATION OR, CLIMATE, ORIENTATION, DIMENSION, SLOPE ...)

The Labyrinth Park of Montendre project is part of the continuity of the existing leisure base, in a desire to promote the site respectful of the environment . The presence of protected areas in the immediate vicinity of the park calls for a particular expectation on the landscape integration of the park supported by an ambitious architectural and environmental approach. The project aims to take advantage of forest amenities while benefiting the site and limiting impacts on the natural environment .

- Oceanic climate / multiple orientations / integration with topographic surveys, slopes and existing landscape lines / 10ha park cut by a municipal road.

Sustainable development approach of the project owner

The proximity of the Natura 2000 zones implies a particular design, sensitive to the environment of the park and its constructions. The project takes advantage of forest amenities by limiting the impact on the natural environment. The following points are particularly developed: - Local wood supply boiler - Fully natural ventilation (Natural Assisted and Controlled Ventialtion), sanitary included - All-wood building : structure, insulation, cladding- Dry toilets for the park- Solar hot water - Local materials: maritime pine and avy stone

Architectural description

The Labyrinth Park of Montendre project is part of the continuity of the existing leisure base, in a desire to promote the site, respectful of the environment. The presence of protected areas in the immediate vicinity of the park calls for a particular expectation on the landscape integration of the park supported by an ambitious architectural and environmental approach. The project aims to take advantage of forest amenities while benefiting the site and limiting impacts on the natural environment. The House of Mysterra is the key to a gradual journey that embraces various points of view to capture on site. It is an overhanging moment, a landscape architecture, belvedere, which articulates the place where it takes place. The bridges link the lake and the park, the open part to the bonded part. On the floor, the reception shop receives the visitor, who enters the park at the turn of the interpretation room. In the lower part are the activities with an outdoor extension: the meeting rooms and the café and a large covered area in the shadow of the building.

The labyrinth park is part of a territorial strategy that makes it an equipment departmental and regional radiation. The project is located near Lake Baron-Desqueroux and is part of the pine forest surrounding it, on a regional scale facing the labyrinths park it also proposes the articulation of uses at the local level open to walkers and the regulars of the lake.

The park house is an overhanging moment, belvedere on both the lake and the park, a landscape architecture that articulates the different levels of the place and the project. In the upper part it hosts the ticket office of the park, a tourist information area, a shop, an interpretation area. In the lower part are set up the entertainment rooms and a space of conviviality which benefits from external prolongations, as well as a large covered space inspired by the balettes of the vernacular architecture.

Reasons for participating in the competition(s)

Le leitmotiv de Mysterra est son intégration dans son environnement immédiat. L’utilisation de la forêt environnante comme ressource permet un apport énergétique sous forme de plaquettes pour le chauffage, mais également d’optimiser le confort d’été. La conception bioclimatique donne la possibilité d’obtenir une température de confort constante malgré un recours exclusif à la ventilation naturelle et l’accueil de publics. Le bâtiment est ainsi traversant et des protections solaires sont présentes au Sud. Des volets en bois au rez-de-chaussée permettent de créer une protection solaire, tout en autorisant la ventilation nocturne sans risque d’intrusion.
Situé en zone sismique, le bâtiment a été conçu selon les normes françaises en vigueur. Le recours à une structure poteaux-poutres bois permet d’obtenir un bâtiment léger particulièrement adapté à cet aléa, notamment dans l’environnement immédiat humide qui caractérise ce site et le positionnement de l’édifice à flanc de colline. Le 20 mars 2019, Mysterra a affronté sans dommages un séisme d'une magnitude de 4,9 à 5,0 sur l'échelle de Richter dont l'épicentre se trouvait à Montendre.
