About this home

Set on a quiet, tree-lined street in the beloved Baldwin neighborhood, this newly constructed Colonial blends modern interiors with period architecture inspired by the area’s turn-of-the-century homes. A long front porch creates a classic first impression. The south-facing main level is filled with natural light and offers an open layout for cooking, dining, and gathering, with a cozy gas fireplace, powder room, and mudroom. Upstairs are three bedrooms, including a serene primary suite with beamed cathedral ceilings, skylight, and spa-like bath with dual shower and double vanity. An additional bathroom with a tub, and laundry is conveniently located on the same level. The lower level features a spacious media room plus a fourth bedroom and full bath. Outside, enjoy a private patio just blocks from Harvard Sq., the Red Line, and neighborhood favorites like Giulia, Moëca, Pavement Coffeehouse, Simon’s Coffee Shop, and Bagelsaurus. Two off-street parking spaces with an EV charger.
