Current Proposals

133 Boston Post Road - Board of Selectmen Approved (with conditions)

Boston Properties has proposed a potential housing development and commercial office space concept for the Biogen Idec/Monster site (133 Boston Post Road). The housing development was discussed as a friendly partnership development in the Housing Production Plan. The proposal was submitted to MassHousing in December 2016 for 345 rental units with 25% set aside at the 80% area mean income (AMI). 
Revised Site Plan - 133BPR
The development, unit count, access, and other site issues need to be worked through with the Planning Board. Ultimately, it will go before the Zoning Board of Appeals for the comprehensive permit, and Town Meeting to modify the development agreement with Boston Properties. If this project is approved, the housing would substantially address Weston's affordable housing shortfall and provide mixed-family rental units, as outlined in the housing needs and strategies identified in the Housing Production Plan.


The Selectmen sent a conditional letter of support to MassHousing in 2016, requesting further investigation into school, traffic and financial impacts to the Town, as well as a request to reduce the total number of units and to find an appropriate access road for the development. The site access is currently proposed for Jones Road in Waltham, which is being heard through its city council.


Details of this proposal, including the site application documents submitted to MassHousing can be found by following this link. To follow the various public meetings of this project, residents should follow the Planning Board, Zoning Board of Appeals, and Board of Selectmen.

Public Meetings

The comprehensive permit hearings through the Zoning Board of Appeals started up again on September 11, 2017.  The hearing process was temporarily halted so that the Planning Board could negotiate some site issues (density and size of the commercial space with Boston Properties.

The Planning Board will be holding a public hearing on September 26th at 7:30 p.m. to solicit resident feedback on the housing and commercial development.
