The $22 million sale of a Beacon Hill townhome has set a new record for Boston’s most expensive single-family home, according to MLS data.

In an announcement on Tuesday, seller Brad Cangiamila of Crest City Capital said the property, a 9,000-square-foot residence at 46 Chestnut St. with three terraced roof decks, had recently undergone a top-to-bottom renovation that took more than two years to finish. The listing price was $25 million.

“This sale validates everything we set out to do,” Cangiamila said in a statement. “Our goal was simple: create the finest turnkey townhouse in Beacon Hill.”

Cangiamila said he plans to take on more projects in the neighborhood.

The transformation began after luxury real estate advisor William Natoli identified the home as a rare chance to reimagine a premier single-family residence.

“From the moment I first saw the property, it was clear this was a once-in-a-generation opportunity,” Natoli said in a statement.

Buyer representation came from Tracy Campion of Campion and Company.

According to the Massachusetts Historical Commission, the Greek Revival building was constructed in 1825.

The restoration included down-to-the-shell construction, executed by Dalfior Development, known for luxury restoration projects in the region. Construction crews rebuilt from the original brick envelope, with new structural framing, floor plates, and modern systems.

“The home had great bones,” said Fernando Dalfior, founder and CEO of Dalfior Development, in an email. “We stripped the building back to its core and shell, completely refreshed the interiors, and invested millions to preserve its uniqueness while delivering a truly modern, multimillion-dollar residence.”

According to Boston Assessor’s records, Crest City Capital bought the property for $8.9 million on Sept. 1, 2023.

Crest City Capital is a boutique real estate development firm headquartered in Wellesley. Since its inception in 2016, the firm has completed 350 transactions, yielding over $580 million in real estate transactions.

When the development team acquired the property, previous owners had converted it into a multi-family building and removed most of the historic interior elements, Dalfior said. The builders intentionally restored the exterior’s historic details wherever they could. They repaired the front door, shutters, and windows, fully repointed the brick facade to match its original character, and refinished the marble front columns.

In collaboration with Embrac Design, the remodeling of the multi-level home features tall ceilings, white oak floors, custom millwork, and elevator access.

The townhome features a primary suite with walk-in closets and his-and-hers baths. Other details include a double-height living space with a custom-carved Breccia Nero marble fireplace mantle that overlooks the garden-level courtyard. The three terraced roof decks above provide panoramic views of the city, including the Charles River.

The home also has its own 15-foot ceiling garage with a staggered car lift, a rare but valuable amenity in this location.

“We’re incredibly proud of the sale,” Dalfior wrote.
