The Binnall House and its 134 apartments will be taking steps toward additional year-round efficiency with the replacement of aging solar panels in coming months.

Residents and employees of the Binnall House hosted a 50th anniversary celebration on Monday for the Retirement Housing Foundation, the group that manages the affordable housing facility.

MassHousing, the state's affordable housing bank, today announced that it has made a $7.065 million loan commitment to preserve affordable housing for low-income and disabled households at the 134-unit Binnall House Apartments in Gardner.
