After four decades of no new developments, in August 2020, construction began on Parcel 12, and construction was expected to begin within the month at Fenway Center pending a final agreement with MassDOT, leading to planned closure of one lane in each direction for a year. Parcel 12 is between Newbury Street, Boylston Street, and the west side of Massachusetts Avenue, and is expected to feature a 13-story Citizen M hotel, a 20-story office tower (including the headquarters of CarGurus), a reconstructed bus shelter, a public park, street-level retail, and a new entrance to the Hynes Convention Center station of the MBTA Green Line subway. The developer of Parcel 13, on the east side of Massachusetts Avenue along Boylston Street, submitted updated plans in February 2020, with 17 stories of condos, hotel, parking, and public space. An approved plan for Parcel 15 (known as 1000 Boylston Street) was cancelled by the developer in August, 2019, with the dissolution resulting in a lawsuit.
