Boston – The Grand Penthouse at the St. Regis Residences has officially become Massachusetts’ most expensive home listed on the market, with a staggering asking price of $49.5 million. This luxury property, located at 150 Seaport Blvd., replaces the previous record holder, Blue Heron Farm in Martha’s Vineyard, which was listed for $39 million.
Spanning over 10,000 square feet, the penthouse boasts two expansive levels designed for opulent living. Key features include six bedrooms, a grand double-height great room, and a distinctive sculptural curved floating staircase with elegant glass railings. The interior is highlighted by a stunning Italian marble radial inlay floor in the grand foyer, designed to create an air of sophistication upon entry.
One of the standout characteristics of the penthouse is its floor-to-ceiling windows, which provide stunning panoramic views of both the Boston Harbor and the surrounding skyline. This connectivity to the breathtaking cityscape reflects the personalized luxury that defines this residence.
Outdoor living is equally impressive, featuring a custom infinity-edge pool with a unique clear acrylic bottom. The pool area also includes a retractable Libart International glass roof, allowing for year-round enjoyment. This luxurious amenity is ideal for entertaining guests or enjoying a quiet day under the sun.
Designed meticulously with an emphasis on luxury living and entertaining, every element of the Grand Penthouse is curated for refined experiences. However, the extravagant lifestyle comes at a price, with monthly homeowners association (HOA) fees reaching nearly $21,870.83 and parking costs adding an additional $1,060 per month.
The building itself provides a 24-hour concierge service, further enhancing the luxury lifestyle experience. Built in 2022, the penthouse brings significant attention to the Boston luxury real estate market, marking a new pinnacle in property offerings in the region.
Prior to the listing of this penthouse, sales in the St. Regis tower had already shown a robust demand, with a combination of units previously sold for over $20 million in 2024. The Sarkis Team at Douglas Elliman Real Estate is responsible for managing the listing of this remarkable property, showcasing the increasing trend of luxury real estate in Boston.
This notable change in the Boston real estate landscape reflects a growing market for high-end properties, offering not only breathtaking designs and amenities but also a lucrative investment opportunity for potential buyers. As the Grand Penthouse at St. Regis Residences attracts attention, it reinforces Boston’s reputation as a key player in the luxury real estate market across the United States.
As buyers increasingly seek out ultra-luxury options, the Grand Penthouse stands as a testament to the evolving dynamics of the Massachusetts housing market.
