Sometimes a listing announcement is straightforward. This one has a few things worth knowing before it hits MLS on June 15.

Unit 704 at Kelton Place is a penthouse duplex  inside one of Allston's most established, full-service buildings, situated on the Allston/Brookline line at Commonwealth Avenue and Kelton Street. It comes to market with two private balconies, two wood-burning fireplaces, exclusive roof deck access, assigned garage parking with an EV charger, and a full building infrastructure upgrade — new roof and new HVAC system — completing mid/late June, covered entirely by current owners. 

That last point matters and is worth saying plainly: whoever buys this unit inherits a freshly upgraded building envelope without having paid for it.

The main level is open and well-connected. Hardwood floors run throughout. A wood-burning fireplace anchors the living area. The granite-counter kitchen opens via a pass-through peninsula to the dining space — a layout that keeps things social without sacrificing function. A half bath completes the main floor. The first private balcony is off the main level, looking west; on a clear day, you can follow the Charles River Basin all the way to the horizon where the Beaver Brook hills begin.

Upstairs, the unit settles into something quieter. Two generous bedrooms, a hall bath, and a primary suite with its own full bath. The second private balcony is up here — a private perch above the rooftops. Both levels have a fireplace, which is the kind of detail that reads as a luxury in a Boston winter.

The 7th floor roof deck is exclusive to penthouse-tier residents. The views from up there — open sky, the Comm Ave corridor, the surrounding neighborhood canopy — are the kind that are easier to show than describe. It is, by any measure, an underutilized amenity waiting for the right owner.

Indoor pool, fitness center, racquetball courts, elevator, attached garage parking (w/ private EV charging station), and professional management through Urban Property Management. The lobby and common areas were renovated in 2024.  The recent 2025-2026 assessments (over $1M) are paid for.  HOA fee is $728/month.

For buyers who have looked at other condos in this corridor and felt like they were choosing between space and amenities — this is the answer to that tradeoff.

Coolidge Corner is under a mile. Carlo's Italian on Harvard Ave — a North End-worthy neighborhood spot — is around the corner, as is Naksan Korean BBQ. Longwood Medical Area is approx. 1.7 miles. Fenway Park is approx. 2.2. The Green Line B train stops at Warren Street directly across Commonwealth Avenue, which means getting anywhere in Boston without a car is genuinely easy, not theoretically easy.

For buyers coming to Boston for work, for graduate school, for the next chapter — this location removes friction from daily life in a way that compounds over time.
