The Boston Globe

A sumptuous penthouse in Boston’s Seaport District is currently the most expensive home for sale in Massachusetts, with a listing price of close to $50 million.
The sprawling six-bedroom unit at 150 Seaport Blvd., listed at $49.5 million, replaced Blue Heron Farm, the Martha’s Vineyard estate where the Obamas often vacationed, as the priciest Massachusetts home on the market, according to Realtor.com.
(Blue Heron Farm is a comparative bargain — cough — at $39 million.)
Known as “The Grand Penthouse” of the St. Regis Residences, the condo occupies more than 10,000 square feet across two levels.
Floor-to-ceiling windows provide sweeping views of Boston Harbor and the city skyline, according to the listing with The Sarkis Team at Douglas Elliman Real Estate.

“Designed with extraordinary attention to detail, the residence features a double-height great room, a sculptural curved floating staircase with glass railings, and a grand foyer with an Italian marble radial inlay floor,” the listing says.

The unit was built in 2022, and there’s a monthly HOA fee of $21,870.83, and $1,060 parking fee, according to listing agent George Sarkis.

“The outdoor living experience is equally extraordinary, including a custom infinity-edge pool with a clear acrylic bottom, and a retractable Libart International glass roof, and sweeping water views from every angle,” the listing continues.
“Blending the privacy of a custom home with the legendary service of the St. Regis brand, The Grand Penthouse is a truly rare offering Boston has never seen.”

The 22-story luxury condominium tower offers 24-hour concierge service, and was home to one of the most expensive home sales in Boston in 2024 after two units were combined and sold for more than $20 million, according to the Boston Business Journal.
