Angell Brook Village is an Active Adult Community in West Boylston, MA consisting of 132 attached townhouse condominiums. Keystone purchased the 35 acre site in 1999 and received a zoning change at annual town meeting in 2002 to allow for this use. The site includes walking trails, a community clubhouse, as well as easy access to major highways, area medical services and virtually unlimited shopping. Four different floor plans, first floor master suites and a rich array of options allow us to meet the needs of today active adults. Construction began in 2005 and 98 homes have been sold to date. Keystone handles all aspects of permitting, construction and marketing of the project as we did with Hillside Village. Each home is built to strict Energy Star standards providing homeowners with 30-40% savings on their energy bills and unparalleled living comfort.
