About this home

Introducing a striking new-construction townhouse in Cambridge’s beloved Baldwin neighborhood. Tucked away on tree-lined Mellen Street, this contemporary four-bedroom, four-and-a-half-bath residence offers the rare combination of modern design and a quiet, residential setting—just moments from Harvard Square and the Red Line. The home’s thoughtful layout includes an open living and dining area with seamless flow to a large private yard and patio, perfect for entertaining. A sleek kitchen, spa-like baths, and generous bedrooms provide comfort and style, while a private garage offers coveted convenience. Old-growth trees and the neighborhood’s calm character make it feel worlds away, yet you’re only steps from City favorites like Giulia, Moëca, Pavement, Simon’s, and Bagelsaurus.
