BHS Expansion Project

In May 2018, Brookline voters supported a debt exclusion override to fund the expansion and renovation of Brookline High School. This building project will include the construction of a new building at the 111 Cypress Street site, (k/n/a 22 Tappan Street), a new Science, Technology, Engineering, and Math (STEM) building to replace the building at the corner of Tappan and Greenough Streets, renovations to the 3rd floor Old Science Labs and Deferred Maintenance of the main building, UAB and the Tappan gymnasium, as well as improvements to Cypress Playground.

​Construction on the Brookline High School Expansion began on June 10, 2019.  Over the next two years, the team of Hill International, Skanska USA Building, and William Rawn Associates, will oversee the construction of a new science wing at the corner of Tappan and Greenough and a new building at 22 Tappan Street. 

Please know that Skanska will work with subcontractors and craftsmen to ensure sensitivity to the surrounding neighborhood, and to maintain a clean and safe job site at all times. Construction is expected to be completed by November 2021. An overview on the project progress for all three sites can be accessed below: ​

STEM Building

The STEM building will be an addition to the high school building that will replace the existing Roberts Wing on the corner of Greenough Street and Tappan Street. It will be a 70,000 square foot building that includes new biology and chemistry classrooms, a makerspace, the culinary arts kitchen and café, as well as administrative and support spaces.

Tappan Gym

The Tappan Street Gym will be partially renovated to upgrade locker rooms and provide spaces for (2) flexible classrooms and an expanded fitness area. Both buildings’ lobbies will be transformed to provide direct access between the two buildings and visibility to adjacent spaces. The renovation will also include Accessibility Upgrades to both buildings. 

The 3rd Floor Renovation project includes cosmetic upgrades and systems modernization that will convert the former science labs into general purpose classrooms, offices, and collaboration spaces.

​The timeline for the renovations and addition at the Tappan Gym and 3rd Floor is to be confirmed (anticipate to be completed by late Fall 2021), pending approved funding appropriation and contract award.
