DOT Block, the proposed development at the fulcrum of Dorchester Avenue and Hancock Street, has expanded its footprint to include another “significant” parcel along Dorchester Avenue–now truly occupying the entire block of Dorchester Avenue from Greenmount Street to Glover’s Corner, project developers told the Reporter today.

RODE Architects, the group behind the mixed-use development, filed a new letter of intent with the Boston Redevelopment Authority today with their updated plans that include the new parcel, which includes the gas station at the Dorchester Avenue and Hancock Street intersection.

The addition creates another 160 units of housing and additional retail space, with ground-floor retail space and apartments built above, said RODE’s Eric Robinson. He added it was too early to say what the configuration of rental and ownership will look like for the new parcels.

All-told, the DOT Block proposed to the BRA today will include 420 units of housing and 68,000 square feet of retail space. Robinson said as the planning process continues, RODE will work to create something that “serves as a real signature-type piece there,” at the Dorchester Avenue/Hancock Street/Freeport Street intersection.

Because of the updated proposal, DOT Block’s architects now plan to make another set of rounds to local civic associations in the coming weeks and months, said Catherine O’Neill, who is representing the developers at community meetings.

With the additional square footage, permitting with the city will likely wrap in the fall, Robinson said, adding: “The anticipation is that potentially shovels will be in the ground in the early part of 2016.”
