Introducing the Mt Auburn Collection: three residences in the heart of Harvard Square, originally designed by Graham Gund and reimagined without a shortcut. This Cambridge Historical Society preservation award-winning building now offers three distinct homes, each pairing custom craftsmanship, Taj Mahal quartz kitchens, Thermador appliances, hardwired Sonos, radiant heat, and 5-camera security, with its own footprint, layout and off street parking. Moments from Harvard University, MIT, and the Charles River, with the Square's cafés, restaurants, shops, and Red Line access at the front door, the collection offers rare flexibility for buyers seeking single-family scale, townhouse living, or a garden retreat — all under one address that sets the standard for Cambridge living.
