Work is underway on a £12m (US$18.6m, €16.6m) extension for Tate St Ives in Cornwall, UK. Jamie Fobert Architects has designed a major expansion for the modern art museum which will double its gallery space.

As well as 500sq m (5,382 sq ft) more gallery space, the new building will house a collection care suite, where larger works can be handled and looked after. The existing gallery, which opened in 1993, is also being improved, with renovations to its learning facilities and roof terrace.

The new building will sit inside a space excavated from the side of the hill, so as not to obscure views out to sea. The gallery will be lit from above by skylights.

According to Jamie Fobert Architects’ website, “the exterior has been designed to respond to the vernacular architecture of St Ives and the natural forms of the coastline.”

The gallery’s original architecture firm, Evans and Shalev, is also involved, and BAM Construction is carrying out the redevelopment works, which are expected to be completed in Q2 2017.
