If you’re in the market for a new home in Cambridge, Massachusetts, consider how this recently listed condo stacks up against other prospects. For starters, it’s unlike any other property around, and the floor plan manages to squeeze four levels into 1,200 square feet. But the twisting shape is more than just for show: A total of eight triangular skylights in each rotated corner work to flood the interior with natural light.

Built in 2006, the home was designed by Uni Architecture, a multidisciplinary firm founded by architects Chaewon Kim and Beat Schenk. The duo—who also acted as the developers and designed three other structures on the same double lot—named this particular unit the XS House, as it’s the smallest of the four homes.

In our 2009 interview, Kim and Schenk describe their challenges finding an affordable home in Cambridge and experience renovating a gable-roofed, 19th-century home that sit nexts door to the XS House.

Although a free-standing residence, the structure is technically classified as a condo given the land use situation. Monthly fees are reportedly under $100 a month to cover some insurance and snow removal. Keep scrolling to see more of the property, currently listed for $849,900.

19 Clifton Street, Unit 19, in Cambridge, Massachusetts, is currently listed for $849,900 by Ed Greable of Keller Williams Realty.
