A Converted Barn Gets a White Stone Extension and a Skylit Dining Room

Architects at EBBA have extended a converted barn house by almost a third, adding a pavilion-style wing framed in white stone. The project, led by the firm's founding director, Benni Allan, is described in Dezeen, which published the story on 9 November 2026.

The starting point was a former farm building with a gambrel roof, the two-sided roof with a steep lower slope and a flatter upper one. Before EBBA's work, the barn had already been turned into a home. Over the years it was changed in small steps, through alterations and extensions added one at a time.

EBBA's approach was to strip some of that history back. The team removed earlier changes to leave open, plain interiors. The original barn keeps its outer cladding of reused cedar shingles, thin wooden tiles that cover the walls.

The new part is different in material and shape. It is built from white stone masonry, chosen to echo the walls along the neighbouring street. Columns of the same stone line its front, creating a covered walkway known as a colonnade, which runs alongside the living space.

Inside the extension, one long room holds a dining area and a lounge. A skylight, a window set in the roof, lets daylight fall over the dining table. Sliding doors open the room onto the colonnade, so the living space and the outdoor walkway can be used together.

The interiors use a restrained set of materials. Walls are finished in plaster, floors in concrete, and the ceilings are white-painted timber laid out in a grid pattern. Taken together, the finishes keep attention on the shape of the rooms rather than on decoration.

For anyone who has wondered what happens to an old farm building once people start living in it, this project offers one answer. It keeps the original structure, removes the layers added along the way, and builds a new wing that speaks to its surroundings. The barn stays visible, and the extension gives the household more room to live in.
