Some of the most interesting homes we've covered were conceived due to constraints in size, budget, or location. That said, there's generally more to work with than 2.5 meters (8 ft, or 99 inches) in width, as was the case with what's thought to be London's narrowest house. It recently hit the market and is expected to fetch at least £450,000 (US$757,000).

Located in Denmark Hill, South-East London, the semi-detached, one-bedroom house comprises a total floorspace of 43 sq m (466 sq ft), spread over two stories. Downstairs, there's a kitchen that's just 1.6 m (5.2 ft) wide, and a combined lounge and dining area that's a little more roomy, at 2.51 m (8.2 ft) in width.

The bedroom and bathroom are upstairs, and measure 2.51 m (8.2 ft), and 1.52 m (5 ft) in width respectively. There's also a surprisingly generous 22 m (75 ft)-long garden out back.

Despite being very, very small, the Denmark Hill home still looks far more practical to live in than Poland's Keret House, which is reckoned to be the world's narrowest house, measuring 1.2 m (48 in) at its widest point, and just 0.7 m (28 in) at its most narrow.

The estate agents report that the Denmark Hill home is currently under offer.
