About this home

Perched on the top floor, this sun-drenched 3BR/2BA penthouse is the one you've been searching for. The living room sets the tone immediately — soaring ceilings with a skylight, an exposed brick wall with fireplace, and rich hardwood floors that run throughout. A true chef's kitchen anchors the space, complete with a pantry for effortless everyday living. Retreat to the expansive primary suite, where a custom built-in window seat and en-suite bath create a private sanctuary. Two additional queen-sized bedrooms offer flexibility for guests or a home office. Step outside to two private outdoor spaces, including a rooftop deck with sweeping water views — the ultimate backdrop for morning coffee or sunset cocktails. Generous in-unit storage and private basement storage round out a home that is as functional as it is stunning. Space, light, and character in one of Boston's most vibrant neighborhoods. Steps to the beach, restaurants, and everything Southie has to offer.
