A Bulfinch Triangle office and retail building formerly anchored by the offices of CBT Architects was acquired by Boston-based Rhino Capital Advisors.

The new owners agreed to assume nearly $14.6 million in mortgage debt from the seller, Boston-based Quaker Lane Capital, according to a Suffolk County deed. The purchase price was $10.

Quaker Lane Capital and private equity firm Alcion Ventures of Boston bought the 7-story, 63,000-square-foot brick-and-beam building in August 2021 for $24 million and announced a repositioning strategy following the departure of CBT Architects, which moved to Constitution Wharf in Charlestown.

The property contains a mix of open floor plan office space and private offices, along with retail space formerly occupied by Boston Beer Works.

Rhino Capital was not immediately available for comment.

Some Bulfinch Triangle property owners are calling on city officials to rezone the commercial district located between North Station and Government Center as a post-pandemic stimulus strategy, lifting the current 100-foot building heights and making it easier to develop multifamily housing.

The Bulfinch Triangle is not included in the Boston Planning & Development Agency’s PLAN: Downtown study, which is designed to encourage housing creation and additional density in neighborhoods including Downtown Crossing and the Financial District.
