It is almost completely Jean Mermoz high school Dakar Senegal 3 EFFICIENT ARCHITECTURE The building of the French high school of Dakar is realized in a new political context where budget restrictions force us to think differently. This strong programme restraint constituted a lever for the project’s sustainable development challenges. In using local resources and know-how to limit imported techniques and products, the project focused not only on territorial and environmental cohesion but also on economic and social cohesion. The project also wanted to highlight that an alternative to Dakar real estate production, which transposes more often than not an international architecture, very much dissociated from the Senegalese context, could exist…It was once more in this spirit of adapting to the country throughout the studies that a Senegalese construction company, GE, awarded the contract to build the high school. 4 5 Inseparable from architectural concept, the common spaces, administration, the environmental steps were taken documentation centre, multi-purpose progressively.

The choice of colours, made with the participation of the Catalan plasticist Miquel MONT, is based on the different shades of laterite which is omnipresent in Dakar and which reinforces the 1 links with the region. A prome- nade therefore features colour sur- prises which punctuate and signal identifiable spaces.
