Situated inside the park that has historically represented the city’s recreational space, the project substitutes a pre-existing pool with a system of new pools whose integration within the site is reflected in both the compatibility of their architectural language and environmental sustainability. The pools appear to recreate the land/water relationship typical of a shoreline; the outdoor space features a sandy beach, picnic areas and spaces for outdoor activities that reinforce the public nature of the site. An ordered sequence of large stone-filled gabion baskets delimits the area of the pool and defines a fence around the entire project. It also defines the geometry of the pavilion containing the reception desk, changerooms, showers and toilets. The Borden Park Natural Swimming Pool is the first public pool where water is treated exclusively using organic processes, with no chemical additives.
