A rendering by RODE Architects shows what new buildings might look like along Pleasant Street in a proposal just submitted to the BRA.

As temperatures begin to rise, the thaw continues on developments around Dorchester, including the large residential complex at Glovers Corner at Hancock Street and Dorchester Avenue.

The expansive setting will have 260 residential units within four-, five-, and six-story buildings, according to the developer’s letter of intent that was filed with the Boston Redevelopment Authority last week. It will also include a 4-story, 400-space parking garage, 40,000 square feet of ground-level retail, and a 20,000-foot landscaped deck.

Construction is scheduled to be done in two phases, beginning with 64 units for both sale and rentals in eight four-story structures along the parcel’s Pleasant and Greenmount Street borders, with 102 total surface parking spaces. There will also be 50 units in an adjacent five-story apartment building, according to the plans submitted by consultant Mitchell L. Fischman. In the second phase, two six-story mixed-use buildings will be erected at Hancock Street and Dot Ave, with 145 residential units in the buildings’ top five floors and 40,000 square feet of retail space on the ground floors.

Because of the project’s proposed size, it comes under the BRA’s Article 80 review process, which is reserved for large developments, and requires an extensive vetting process.

Meanwhile, a few miles away, on Columbia Point, the Boston Teachers Union received BRA approval for its $23 million initiative to replace its current headquarters building. In another two-phase process that is expected to begin this coming December 2015 and finish up by February 2017, the BTU will first demolish its current building and in its place construct a three-story building that will hold the BTU offices, optical shop, a credit union, and function hall. The second phase will begin thereafter and involve the construction of a 300-space, two-story parking garage, which, the BRA noted, will help to alleviate the current need for BTU visitors to park in UMass Boston lots.
