WEST ELEVATION The wetland is also one of the last known breeding sites of the Western Leopard Toad, an endangered species. In order to allow the toads’ safe passage, concrete culverts were constructed underneath the road, and the slope of embankments carefully designed to allow the toads to traverse them. Earth ramps were also incorporated on the upper reaches of the estate to allow the toads to move easily to the breeding ponds. The extensive rehabilitation programme was well established by the time the art gallery opened. Design Concept The Norval Foundation was envisioned by the architects as a modern pavilion for art, set against a dramatic mountain and vineyard landscape. It is a pure expression of form; a bold rectangular mass, The Norval Foundation delineating its heavy walled enclosure and light, over-sailing roof. The building is constrained by the linear site, between a busy road and an existing wetland; turning its back to a neighbouring embassy compound. The linear circulation spine is positioned along this edge, with the galleries and public spaces facing the natural landscape, capturing framed views of the wetland, vineyards and mountains beyond. The building sits in an elevated position, and shields the wetland, creating a private space for the sculpture park and forms an inhabited threshold between public and private zones. A triple volume atrium establishes a deliberate visual connection between these zones; one urban, the other natural, and provides a physical transition between these contrasting environments. 35
