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 scheduling of the landscaping project has yet to be determined.
