Following a design competition, the practice was commissioned to create a visitor centre for the Teifi Marshes Nature Reserve. The brief was to provide an all-weather building that would be sensitive to its situation, sustainable in design and energy efficient in operation. The team located the Centre on an escarpment overlooking the reed beds that form the focus of the nature reserve, but the building is not intrusive. It is largely concealed by the incline and its footprint is small. The building's ‘backbone’ is formed by a robustly detailed, curved ‘range’ which follows the topography of the escarpment. Exhibition, shop and restaurant areas are accommodated in a dramatic double-storey glass volume with spectacular vistas. School facilities are located in the lowest level of the building, which is formed from a battered slate plinth. The team used contrasts in the design to surprise and delight visitors and to echo the special qualities of the landscape.
