The town sold the Ames Schoolhouse at 450 Washington St. decades ago, but now selectmen are looking into getting it back. Selectmen announced last week they authorized $60,000 to be spent for architectural firm SH&A to provide cost estimates for using the building as a town hall and senior center, according to selectmen chairman Michael Butler in a phone interview Wednesday. The firm will also look into expanding the firehouse next door to the schoolhouse, building a police station on the site of the current town hall on Bryant Street. The idea of using the school came from resident Shaw McDermott, who spoke against a municipal campus building project on Rustcraft Road during fall Town Meeting last year. The Rustcraft project vote subsequently failed. The firm’s results will be presented to selectmen in March, according to Butler.
