Sunday, May 21 from 12-5pm. Durant-Kenrick House and Grounds (286 Waverley Avenue, Newton).

Historic Newton’s annual Newton House Tour is back in person for its 40th year. Tour goers are invited to look inside remarkable historic properties not usually open to the public.

This year’s House Tour will feature a fully electric historic home on the National Register of Historic Places. Three years ago, the home underwent a renovation to make it highly energy efficient and to move off of fossil fuels. The owners converted from natural gas baseboard heat to ducted heat pumps for heating and cooling, shifted from gas to an induction stove, added solar panels on the roof, and insulated and air sealed with closed cell foam which has a highly insulative value. The home also added an energy recovery ventilator for fresh air exchange while minimizing heat loss. The solar system on their roof covers 70% of the home’s energy needs with an estimate that they will break even 4 years after installation.

Tickets are $55 in advance and $45 for Historic Newton members. Day of tour: $60 for all tickets. The self-guided tour starts with ticket pick-up at the Durant-Kenrick House and Grounds, 286 Waverley Avenue, Newton. Purchase tickets here or visit Information: 617-796-1450. Proceeds from the tour benefit Historic Newton.
