Inside Boston’s Most Jaw-Dropping Penthouse: A Rare Double-Unit Sky Residence at One Dalton
It’s not often that attached living feels indistinguishable from a private estate—but on the 58th floor of Boston's Four Seasons One Dalton, a remarkable penthouse achieves the near-impossible.
Perched above the city in the tallest residential building in New England, this 7,848-square-foot masterpiece wraps two corners of the tower—an ultra-rare double-unit configuration that creates the sensation of a single floating home, complete with sweeping, cinematic views from every room. Originally built in 2020 and extensively reimagined in 2022 by the acclaimed Lagasse Group, the residence is now a turnkey offering unlike anything else on the Boston market.
Step inside and the tone is set immediately: solid white oak floors, stately moldings, and museum-quality custom millwork begin a thread of craftsmanship that runs through every inch of the home. The primary kitchen, a showstopper in luminous white onyx, feels suspended in the skyline. Outfitted with top-tier appliances and a sculptural breakfast bar, it flows seamlessly into an informal dining and family room where walls of glass frame the city from dawn to dusk.
For formal gatherings, the residence reveals an entirely new mood. An eye-catching living room features an Art Deco–inspired wall of glass that unfolds into a glamorous dining room, a temperature-controlled wine room, and a fully equipped catering kitchen—making the home equally suited for quiet, private living and large-scale entertaining.
Five bedrooms, six full marble-clad baths with radiant heat, and two elegant powder rooms ensure comfort and privacy for residents and guests alike. The integration of tech is equally factored in for daily ease: a comprehensive Lutron lighting system, fully automated shades and blackouts, and a whole-home A/V setup with surround sound bring convenience and ambiance to every space.
And because this is One Dalton, residents enjoy 24-hour Four Seasons Hotel services, from in-residence dining to concierge and lifestyle amenities.
Listing agent Michael Harper, a Luxury Property Specialist with Coldwell Banker Realty in Boston, calls the property, "one the most luxurious penthouse offerings in Boston."
