The project for the facilities of the High Performance National Sailing Centre in Santander, consists in changing the previous obsolete storage buildings for a new building over which we have planned a public rooftop. The project presents the problem of integrating in a limited space two activities that must be physically segregated – private use of the CEAR and public use of the canopy – while simultaneously creating a whole whose parts harmoniously coexist. Our proposal is to extend the public space above ground level, ensuring both storage and public space functions can be combined through an unconventional approach to public space design. This project is an opportunity to bring both city and citizens closer to the harbour through a design that integrates an elevated rooftop viewpoint; to design a facility that fits with the bay masterplan we designed in collaboration with Arup; to generate wider and clear views to harbour and the bay of Santander.
