In this lower-ground room, which doubles as a spare room for guests, internal windows and a glazed door separate the space from the hallway. This brings as much natural light as possible into an area that would otherwise be quite dark. Walls in warm ‘Buff ’ and woodwork in ‘Milk White’, both from Edward Bulmer Natural Paint, contribute to the airy feel, and a sofa bed in a rich yellow brushed linen-cotton from Sofa.com can be converted easily for guests.
