20 Sumner Road

House Zero

The Harvard Graduate School of Design interior renovation and exterior renovation construction project at 20 Sumner Road is nearly complete. The project encompasses an energy retrofit of the existing 20 Sumner Road house and property to target ambitious sustainable goals that can work within the context of a traditional wood frame house. The house’s siding, roof, windows, cooling system, and other building materials, were replaced. The project also includes landscaping and accessibility upgrades. The University’s contractor mobilized the week of April 22, 2019 to commence landscaping activities. This project is scheduled to be completed within 6-8 weeks. There will be many deliveries and the use of larger equipment, both of which will generate noise. General work hours will be 7AM-4PM Monday through Friday, and occasionally Saturdays 9AM-4PM.
