Mayfly Cottage by Stiff + Trevillion, UK

The two-level, 310sq m house, created with traditional construction methods from the area, is the architects' reinterpretation of a rural barn on the River Test in Hampshire
The new building sits on the grounds of a listed manor house, on a plot where an old cottage once served as ancillary accommodation
'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.'

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
