Inside a London ‘gap house’ that is selling at US$1.4 million

At only seven feet and seven inches (2.3 metres) wide, the aptly named “Slim House” in London’s upward-trending Clapham neighbourhood, might be the narrowest slice of yuppie heaven. 

But the home, narrower than a train carriage, is more expansive than it seems, offering four bedrooms over 1,058 square feet.

The building first cropped up on design-savvy radars in 2013, not long after local firm Alma-Nac gave the space – an original “gap house”, meaning it is squashed between two larger buildings – a complete makeover. 

The company tacked an additional room onto each floor and added a sloped, skylight-pocked roof and a lush, 48ft (14.6m)-long, landscaped garden. 

Custom-made shelving units line the skinny property, which helps sidestep storage issues.

At the time, Alma-Nac partner Tristan Wigfall told design magazine Dezeen that “with such a narrow and deep plan the existing building was claustrophobic” (no kidding) and that “the key driver in developing the proposal was ensuring that natural light was able to penetrate deep into the plan to create rooms that felt spacious and light”.

The property got plenty of attention, even making a cameo on the popular British television show, G eorge Clarke’s Amazing Spaces.

Now the house is on the market for £1 million (US$1.4 million); in Clapham, the average price of a four-bedroom house is £1.3 million.
