In December 2024, the development team behind Frost Terrace Apartments, a 40-unit 100% affordable development completed in 2021, purchased six contiguous sites (20 Roseland Street, 22 Roseland Street, 28 Roseland Street, 1 Frost Street, 3 Frost Street, and 5 Frost Street) where they intend to create another affordable development. The approximately one-acre parcel is adjacent to Frost Terrace and will be called Frost Terrace II. Located in the heart of Porter Square, surrounded by many amenities including restaurants, retail stores, and the Porter Square MBTA station, the combined parcels total 127,668 square feet and currently contain five multi-family buildings and one single family house. The team plans to create this affordable housing under the provisions of the Affordable Housing Overlay (AHO).
