The developer who in 2021 proposed a new six-story building across four parcels of land on Dorchester Avenue has reduced the number of residential units and added ground-floor commercial space.

The project, located at 1320 Dorchester Ave., a short walk from the MBTA’s Fields Corner Red Line station, now has 70 units, instead of 80, and 1,790 square feet of commercial space. Nine units will be designated as affordable housing.

All of the units will be studios, ranging from 377 to 450 square feet, in order for the project to be “fully compliant” with the city’s “compact living” guidelines. The “compact living” guidelines allow developers to build small units as part of an effort to ease the city’s housing crunch.

A virtual public meeting on the project is set for Dec. 13 at 6 p.m. In a supplemental filing dated Nov. 17, the project’s developer promises “tens of thousands of dollars” in revenue to the city of Boston and the creation of 80 construction jobs.

The project is being developed by 1334 Dot LLC, which lists Robert F. Raymond as the manager. George Morancy of South Boston, as legal counsel, and Choo & Co. of Quincy as the architect. Doug George of Walter Huntington Construction LLC is tasked with construction management.

Morancy, in the supplemental filing, said the changes are “adjustments made in response to comments received during the project’s community review process.”

The site currently has a small residential and commercial building, and most of the parcels are used for parking. The developers propose six parking spaces, with none for residents, citing the proximity to the Fields Corner MBTA Station.

The project also calls for a 685-square-foot fitness center and a 1,000-square- foot workplace/lounge area. A bike sharing and repair station, as well as a 1,336 square foot roof deck, are also in the plans.
