The Boston Redevelopment Authority’s (BRA) board recently approved a number of different projects throughout the city, including a new master plan submitted by the Wentworth Institute of Technology.

The 10-year plan submitted by Wentworth includes five new projects, two of which are expected to break ground in 2011. The first project will include the construction of a 7,000-square-foot, two-story addition and the renovation of 23,000 square feet of existing space and will cost $10 million. The second project, a $12 million, 18,000-square-foot, three-story building addition, will provide new teaching laboratories, classrooms and offices for Wentworth’s math and science curriculum.

A $150 million residential project was approved for 319 A St. in Boston’s Innovation District. It will bring new rental housing in the form of a 268,500-square-foot, 21-story, 180-foot-tall building that will house 184 apartments, according to a statement. The rental complex will also include 19 affordable housing units and five affordable artist live/work units at 63 Melcher St. Construction is scheduled to begin in the third quarter of 2011 with an estimated completion date in the third quarter of 2013. Archon Group L.P. and Goldman Properties will develop the project.

A $62 million, 183-room extended stay hotel at 121 Brookline Ave. in the Fenway/Longwood areas was also approved. The project is scheduled to begin construction in fall 2011.

The Energy Positive (E+) Green Building Demonstration also won approval. The program is a residential design and construction initiative that will bring energy positive green homes to Boston’s neighborhoods, according to a statement.

Finally, developer Mount Vernon Co. was given the go-ahead to transform Allston Garage site at 9-23 Griggs St. The $23 million, 36,377-square-foot, 100-unit resident project is expected to "enhance pedestrian activity" along Griggs Street and Brainerd Road with new residential uses including the creation of new open green space, according to a statement.
