The family that owns Down Home Delivery & Catering at 2 Bowdoin St. in Four Corners has filed plans to replace their building with a 7-story apartment building, with 2,400 square feet of ground-floor space for their restaurant to move back into.

The Webster family’s proposed 22-unit building would be one story taller than a typical modern Boston apartment building because rather than the ordinary construction of a steel-and-concrete “podium” topped by five floors made of wood beams, the entire structure will be built out of cross-laminated timber, a strong wood product that means fewer carbon emissions than from creating steel and concrete, according to the family’s filing with the Boston Planning Department.

The building would have 5 one-bedroom apartments, 10 one-bedroom apartments with dens and 7 two-bedroom units. Four of the apartments would be rented as affordable. There would also be a roof deck for residents.

The building, which is near the 23 bus route on Washington Street and less than a half mile from other routes and the Four Corners/Geneva Fairmount Line stop, would have no parking.

The filing includes letters of support from the United Neighborhood Association, the Mt. Bowdoin Betterment Association, Four Corners Main Streets, state representatives Chris Worrell and Russell Holmes and state Sen. Nick Collins.
