A developer is proposing the construction of a multifamily development at 1471 Blue Hill Ave. in Mattapan. 

According to the small project review application filed with the Boston Planning & Development Agency on Oct. 3, the 27,164-square-foot lot currently houses two billboards within Mattapan Square’s Community Commercial Subdistrict. 

The proposal seeks to redevelop the property and construct a five-story residential building with 48 affordable units, parking for 12 vehicles and a community art space/work room. It also includes improved pedestrian access and landscaping in the area.

According to the developer, the project will be a “high-performance, energy-positive building, producing more energy than it consumes,” as part of Boston’s E+ Green Building program. Designed to Passive House standards, once complete, the development will be the largest Passive House building in the city, according to the filing. It’s also expected to be LEED Silver certified.
