The former Boys Club building in Worcester's Lincoln Square is being proposed for redevelopment as part of a 95-unit senior living facility. The project would be built by Boston-based WinnCompanies, the same firm that created the Voke Lofts apartments a block away and the Canal Lofts on Water Street. The development is slated to begin next year. As a first step, Winn needs City Council approval to construct a new five-story addition to the old Boys Club to include 64 of the project's units. Some of the building would rise over a road tunnel that passes under Lincoln Square, for which Winn is proposing to pay the city $100,000 for what are known as air rights for building above the roadway.
