Award-winning design and transformation in the heart of Harvard Square. Originally designed by Graham Gund, this 2,870 SF detached single family condo offers 4 bedrooms plus a home office and 4.5 baths across 4 levels, living like a private home. The main level is one open, light-filled space for living and dining, anchored by a stunning kitchen with a Taj Mahal quartz island, Thermador appliances, and a pot filler. Custom built-ins, a fireplace, a hidden powder room, and a private fenced patio complete the floor. The third floor is a primary oasis with skylights, a wet bar, and a Porcelanosa spa bath with soaking tub. The second floor offers a second ensuite, a third bedroom, a home office, a full bath, and laundry. A private lower level with separate entrance, its own laundry, and heated floors adds rare flexibility. 100% electric, hardwired Sonos, 5-camera security, and 1 parking spot. Minutes from Harvard, MIT, the Charles, and the Red Line, with Harvard Square's cafes and restaurants just minutes away.
