'A sustainable approach was key,' explains lead architect Chris Eaton. 'This was led by using a combination of local materials and tradesman and traditional construction methods in a contemporary fashion.'

Exterior view of cottage

Though the architects designed all internal details, down to the joinery, the owners were heavily involved in every stage. Having worked with Stiff + Trevillion on two previous properties in Putney and Kensington, they had a solid relationship with the architects and remained a key part of the process

Sticking to local techniques, environmentally friendly features and natural materials like handmade bricks and roof tiles, charred timber cladding and green oak for the frame, Stiff + Trevillion cleverly translated the barn's vernacular typology to a space fit for 21st-century living
