Sustainable development approach of the project owner

The Costebelle gymnasium, which is part of the sustainable building approach to the Mediterranean, displays a deliberately stripped architecture.
The project is based on three principles: the sobriety of use, the austerity of technical means and the affirmation of raw material.
The use value and the consideration of people and their environment are instinctive principles that guided the insertion of the project. Sharing with neighboring facilities makes possible to promote the reconstruction of the site.

Our approach to bioclimatic design is based on the reduction of consumption of the building and its ease of maintenance. An environmental logbook was given at each phase to clarify the answers proposed for each BDM label.
A specialized design office has accompanied the companies in the construction phase on the air-tightness of the building.

Architectural description

The gymnasium is in the form of a compact composition, consisting of a hall in structure and wood facing near which two volumes of raw concrete are inserted: changing rooms and depots.

The geometric net developed from the basic figure of the triangle dynamically plays with the light and allows to open the sports hall on a forest of cork oaks to the south and the Costebelle stadium in the North which offers a wide clearance on the landscape .
No cladding or skin added, Larricio Pin (local resource) is left apparent holding the role of exostructure, curtain wall and sun protection.
The immaculate whiteness of the room contrasts with the shady color of the pre-shaded rafters in order to be confused with the trunks of the surrounding trees.

Building users opinion

The occupants are very satisfied

If you had to do it again?

We have a regret about the external facilities that were not realized according to the master plan drawn up by our team.

    Building structure

    The project required a very large quantity of class 4 wood with large sections. This volume required a reasoned approach because few sawmillers usually have such a stock, and the tender for the carpentry lot included a "Bilan Carbone" criterion in order to give priority to local timber in the choice of supplies the company. Laricio pine from Calacuccia (Corsica) being still little known stocks were available and the Carbon balance excellent.
