How skinny? 3.1 metres wide… that’s three longish strides (in the same direction). Westminster Council has approved the plans to convert an alleyway between the BBC’s Grafton House and the Green Man pub on Euston Road near Great Portland Street Tube. There’ll be three bedrooms, two bathrooms, a ground floor courtyard and kitchen/diner below ground comprising in total some 1,500 sq ft. Its unique-ness will make this hard to value, but the location is expected to push it to somewhere between £1m and £2m. Architects… HOK. For another 3m wide house (in Japan), go here.
