About this home

Introducing the Mt. Auburn Collection: three residences in the heart of Harvard Square, originally designed by world-renowned Graham Gund and completely reimagined in 2026. A recipient of the 2026 Cambridge Historical Commission Preservation Award, the collection offers three distinct homes, each with custom craftsmanship: Taj Mahal quartz kitchens, Thermador appliances, soft-close cabinets, hardwired Sonos, heated floors, and state-of-the-art CCTV. Each home has its own unique footprint, layout, and off-street parking. Minutes to Harvard, MIT, and the Charles River, plus the shops, cafes, and restaurants of Harvard Square. Easy access to the Harvard Square and Central Square Red Line stations, Storrow Drive, Memorial Drive, and the Mass Pike. Rare flexibility for a wide range of buyers, all under one address that sets the standard for urban living.
