A Cambridge-based online automotive marketplace and Dutch pod-style hotel chain will anchor a high-profile Massachusetts Turnpike air rights development.

CarGurus said today it’s leased 275,000 square feet on the upper 11 floors of the 20-story office building branded as 1001 Boylston. Banker & Tradesman was the first to report CarGurus’ negotiations with the Boston-based developer on what would be the first commercial development built on air rights in Boston since Copley Place nearly 40 years ago.

The project’s second building, a 13-story, 144,000-square-foot hotel, will be operated by Dutch boutique chain citizenM, developer Samuels & Assoc. announced today. CitizenM planted a flag in the Boston market in August with the opening of its 272-room hotel at The Hub on Causeway, featuring 170-square-foot rooms and an amenities floor including a cocktail lounge, conference rooms and shared workspace.

“They have a great design team and this will be a unique brand for Back Bay,” said Peter Sougarides, executive vice president at Samuels & Assoc.

The project will flank the Turnpike on MassDOT’s 1.8-acre air rights parcel 12 near the Prudential Tunnel entrance. Construction of both buildings is expected to begin next spring, Sougarides said, following completion of a lease agreement with MassDOT.

CarGurus will consolidate its workspaces from three locations in East Cambridge. Completion of the Back Bay tower is scheduled for 2023 and will include a rooftop CarGurus logo visible to an estimated 140,000 Turnpike drivers daily.

“The Back Bay office market has been extremely strong and it speaks to how in-demand and desirable it is,” Sougarides said.

CarGurus reported net income of $65.2 million on revenues of $454 million in 2018.

The project will include a new public plaza on the west side of Massachusetts Avenue and terrace overlooking the Turnpike. It also involves changes to the intersection of Newbury Street and Massachusetts Avenue, including relocation of the Turnpike on-ramp slightly north of its present location.

Samuels & Assoc. also will build a new headhouse for the MBTA’s Hynes Convention Center station on the west side of Massachusetts Avenue and renovate a long-dormant pedestrian tunnel linking to the existing station entrance on Newbury Street.

Plans for another Back Bay air rights development called 1000 Boylston collapsed this summer amid a dispute between developer Weiner Ventures and Suffolk Construction, which filed a lawsuit in October seeking $100 million in damages.

And Meredith Management, designated developer of the Fenway Center air rights project, recently submitted updated plans replacing housing with a 550,000-square-foot office-lab building. That project would be built between the Beacon Street and Brookline Avenue overpasses.
