A joint venture between a Swiss investor and Boston-based Center Court Boston LLC is proposing a 31-unit luxury condo tower at 171 Tremont St. in Boston.

The project would replace a five-story, 17,742-square-foot commercial building that is currently vacant with a 355-foot-tall tower overlooking Boston Common, according to Dennis McKenna, an attorney for Boston-based Riemer & Braunstein, which represents the developers.

Matthew Snyder and David Ridini, principals of Center Court Boston LLC, plan a joint venture with Swiss investor Maurice Dabbah on the project. The ownership group also includes developer David Raftery of Boston.

The new development would occupy the 3,200-square-foot footprint of the existing building, with each unit taking up an entire floor, McKenna said. The height conforms with shadow regulations for development near Boston Common, but would need a height variance from the Boston Redevelopment Authority (BRA), McKenna said.

“The goal is high-end luxury boutique condos. The finishes and interior would be first quality and that’s going to be the design of the building throughout,” McKenna said.

The developers will begin an outreach campaign with numerous neighborhood associations in the Chinatown, Beacon Hill and Midtown Cultural District areas shortly, McKenna said.

Elkus Manfredi Architects of Boston is drawing up the plans along with engineering firm VHB. A major project filing with the BRA is expected within 30 days.
