One Dalton’s 23-story, 215-key hotel component has topped off, and work has begun to construct the tower’s 180 luxury condominium residences and exclusive amenity spaces on floors 24 through 61. About 20 stories of One Dalton’s blue glass curtain wall facade have been constructed, and the tower is now beginning to surpass the height of the adjacent 30 Dalton and Sheraton Hotel towers on its’ way to becoming the Back Bay and Boston’s third-tallest tower at 61 stories and 740 feet high. One Dalton’s concrete superstructure is expected to top off in mid-2018, with completion expected by late 2018.

Condominiums at One Dalton are now on sale starting at $2.75 million. At the tower's summit will be three two-level Penthouse Estates, two of which are reportedly under agreement.

Michael Dell scoops up second Boston penthouse at 61-story One Dalton tower

Dell Technologies Chairman & CEO Michael Dell has reportedly entered a contract to acquire one of three $40 million penthouse residences atop the 61-story One Dalton tower under construction in the Back Bay, which, following Dell’s acquisition of a Millennium Tower penthouse residence last year, would make Dell the owner of penthouses at both of Boston’s, and New England’s, tallest residential towers. Per a Wall Street Journal report, Dell’s penthouse will be approximately 7,300 square feet in size across two stories, with a 570-square-foot outdoor terrace.

Listed for sale at $40 million each, One Dalton’s penthouses are expected to be Boston’s most expensive ever sold, nearly 15% higher than the $35 million, 13,000-square-foot Millennium Tower penthouse acquired by billionaire John Grayken in 2016. Sales of condominiums at One Dalton have not yet closed. Dell purchased his 4,110-square-foot Millennium Tower penthouse for $10.9 million, closing on the residence in December 2016. Dell Technologies acquired Hopkinton, MA-based EMC Corporation for $60 billion in Fall 2016.

One Dalton will be Boston’s third-tallest building at 740 feet and 61 stories tall, featuring 180 private luxury condominium residences above a 215-room Four Seasons luxury hotel. Completion of One Dalton is expected in Fall 2018. The building has reached nearly half of its’ full height and is expected to top off in early 2018. The following is a photograph of One Dalton:

One Dalton residence sells for $40 million, setting new Boston condominium sale record

A luxury residence at the Back Bay’s upcoming 61-story One Dalton tower has reportedly sold for $40 million, which would surpass Boston’s current condominium sale record by $5 million. The sale of a 13,000 square foot penthouse at Downtown Crossing’s Millennium Tower closed last August for $35 million, claiming Boston’s current sales record. The Millennium Tower penthouse sold for nearly $2,700 per square foot; square footage of the One Dalton residence which sold for $40 million has not yet been revealed.

Sales of One Dalton’s 180 luxury residences have not yet closed; a number of residences are reportedly under agreement with sale prices starting at $2.5 million. In an interview with Bloomberg, Richard Friedman, CEO of One Dalton developer Carpenter & Company, said that One Dalton is “the fastest-selling residential project in Four Seasons history,” and that about 90% of One Dalton buyers are American, with a large majority hailing from Boston. “We’ve sold to no Russians. Maybe one person from China, but they have a relationship to Boston, and a few units to people from Europe or the Middle East,” said Friedman.
