More than 25 volunteers from Berkshire Gas Co. and Wayfair, above and below, lent a hand Friday to Central Berkshire Habitat for Humanity at the new Gordon-Deming Village at 52-62 Gordon St. in Pittsfield. The three-building complex will feature six town houses. Allegrone Cos. is overseeing construction on the project, and Habitat still is accepting applications for five of the six units.
