A South End brownstone is a mainstay on real estate wish lists, and that hallmark of Boston living doesn’t get much better than 21 E. Concord Street.

Set within that timeless footprint, this beautifully scaled two-family home pairs the architectural details house hunters crave with modern flexibility. And, most notably, there’s a pair of full off-street parking spaces. We’d put that under our tree any day.

High ceilings and elegant moldings set the tone as you enter the owner’s residence, where generous living and dining rooms are thoughtfully divided by pocket doors, creating spaces that feel both open and intimate. An updated kitchen anchors the parlor level, making everyday living and entertaining feel effortless.

Upstairs, the primary suite enjoys its own bath, while additional bedrooms, baths, and a tucked-away office nook offer room to grow, host, or work from home. The top floor presents an opportunity to reimagine the layout into a full-width retreat, capped by one of the home’s most compelling features: a private roof deck spanning nearly 500 square feet, an urban getaway with views, perched above the city.

The lower-level two-bedroom, two-bath residence provides built-in income potential or the option to reunite the home into a grand single-family townhouse. A walkout unfinished basement offers yet another layer of future upside, ready for a creative vision.

All of this sits in the heart of the South End, just moments from the city’s best foodie spots, plus cafés and boutiques along Tremont Street, with easy access to public transportation to boot.

The sale of the residence, on the market for $2,999,000, is represented by Paul Campano, Keller Williams Realty Boston Northwest, 617-304-3686.
