The architectural competition for this new visitors centre was won by Heneghan Peng who proposed a discreet highly sustainable solution for this world heritage site.
The visitor attraction on this site is a spectacular crystalline basalt outcrop so basalt was chosen as a primary façade material arranged as a series of stone piers vertically punctuating the tapering south and east elevations. The piers were up to 5 meters high and varied in width from 600mmm to 100mm. In order to stabilise the thinner piers against wind load the piers were pre-stressed with stainless steel rods.
The glass panels were detailed to conceal the frame behind the stone.
Construction budget: £10M
