Big Dig House

Location: Lexington, Mass.

The Big Dig house from Single Speed Design takes its name, and its building materials, from Boston’s Big Dig. More than 600,000 pounds of salvaged materials are used in the house, including sections of highway I-93. The house was built quickly and the road sections were placed as-is onto the steel beam frame, so that what was once Boston’s Central Artery is now this house’s floors and roof. The house also has roof gardens that use collected rainwater.
