Adam Khan Architects has unveiled proposals to restore Barbara Hepworth's second art studio, returning part of the building back to its former use as a dance hall.

The building has remained untouched since Hepworth’s death in 1975 but is now set to be restored by its owner, The Tate Gallery St Ives, with National Lottery funding.

Adam Khan Architects, which won a competition last year, plans to restore the dance hall on the building’s upper floor, with a 24m-long sprung maple floor, a stage, and recreated glassine screens designed by Hepworth herself.

Meanwhile, the lower ground floor of the building would be turned into spaces to learn about Hepworth’s life and art.

These would include a recreation of her working studio and a section of grid-marked floor with the carefully preserved outline of her famous sculpture.

An outside yard, which Hepworth used to make larger sculpture prototypes, would be opened to the public for the first time, including a ‘creative studio’ to host both Tate St Ives’ programme of artist residencies and sculpture workshops for visitors.

A new lift and staircase would make the building fully accessible, with access to a balcony that overlooks the dance hall, and to a projection room with original 1930s graffiti.

Barbara Hepworth worked in the Palais de Danse on the prototype for the United Nations in January 1961.

The building was gifted to the Tate St Ives by the artist's estate in 2015.

The estate had also previously gifted its neighbour, the Palais de Danse.
