About 9b Mt. Auburn Street #b

Behind a storied exterior, this 2746 SF award-winning attached townhouse, originally designed by world renowned Graham Gund, blends modern refinement with understated elegance in the heart of Harvard Square.

Bespoke millwork and an ambient fireplace anchor the entertaining space, alongside a chef's kitchen centered on a Taj Mahal quartz island with panel-ready Thermador appliances. The top floor houses the primary suite alongside an office/den, with vaulted ceilings, custom walk-in closet, and a spa-inspired ensuite with a spacious shower. The second floor offers a second ensuite along with a third bedroom, laundry, and a full bathroom. A flexible finished lower-level offers a fourth bedroom, guest suite, or office with a full bathroom, radiant tile floors and a media room. Private entrance, hardwired Sonos, CCTV security system, and assigned parking for one car. Moments to the Charles River, two MBTA redline stops, Whole Foods, and all the cafés, shops, and restaurants that bustling Harvard Square has to offer.
