Harvard Square townhouse that Bell and Fandetti designed on sale for $958,000

Unit 6 at 36 Irving Street in Cambridge’s Harvard Square area is a 1,465-square-foot townhouse in the Bell and Fandetti tradition.

It’s on sale now through the Petrowsky Jones Group, and it has the look of a glorified treehouse—in a good way.

A little background: From 1973 to 1981, architects Doug Bell and Gerald Fandetti designed about 20 clusters of townhouses in Cambridge for a grand total of approximately 170.

Distinctive for features such as levels setting apart rooms rather than walls and a resultant capaciousness, the townhouses (some are deeded as condos) were also considered particularly energy-efficient for the period. There was also a lot of wood and natural light involved; and sometimes a deck, too.

Unit 6 at 36 Irving reflects these features. Check it out.
