Winstanley updates timeline on 101 College bioscience tower

As cranes swiveled behind him and heavy equipment roared, developer Carter Winstanley gave a progress report on the construction of a new bioscience building at 101 College St. in New Haven on Tuesday. 

Workers have roughed out the first four floors of the new building in steel, Winstanley said, and are expected to top out the entire building by the end of the year. Tenants could move in as soon as the third quarter of 2023.

“We appreciate the patience of all of the residents and commuters who have been very careful threading their way through the various traffic patterns that we've set up over the last year,” Winstanley said. “I assure you it’s not an easy task to build a building over two active traffic lanes, eight traffic lanes on either side.”

The 10-story tower at 101 College St. is slated to house 500,000 square feet of laboratory, research and meeting space. The new building faces 100 College, another Winstanley development, a tower that houses Alexion and Yale University laboratories.

Winstanley broke ground on the 101 College St. project in June 2021, promising that it would bring new jobs to the city and cement New Haven's status as a regional biotech hub.  

New Haven-born Alexion is among the companies that have announced they would move into the new tower. 

Alexion, AstraZeneca’s rare disease group, announced in April that it would expand its research capabilities in New Haven with space at 101 College. Alexion said it planned to occupy the new facility by the end of 2023.

Other announced tenants include Arvinas, Yale and BioLabs of Cambridge, which has said it would run a new Yale-backed incubator in the building.

In addition to new bioscience space, Winstanley’s 101 College development is a key link in the Downtown Crossing Project, an infrastructure effort aimed at relinking streets and neighborhoods divided by highway building in the last century. 

Winstanley also emphasized that the project was being run as a model of inclusive growth, maximizing the number of residents of adjacent neighborhoods hired for construction work. 

“Additionally, we're trying to open the building up,” Winstanley said.  “This building has a public corridor that runs from one end of the building to the other, and we're inviting the community to use that corridor as a walk from the train station into the downtown.”

Melissa Mason, executive director of New Haven Works, at a news event about 101 College St. on July 26, 2022.

New Haven Works Executive Director Melissa Mason said that the project had become a template for deals with developers on increasing workforce participation from underserved neighborhoods. Winstanley Enterprises agreed to give top priority to job applicants from the nearby Hill, Dwight and downtown neighborhoods. 

“Our agreement around 101 College created a new standard for partnership agreements with employers across the city,” Mason said. “We've been able to hold up the commitments in this agreement as an example of what responsible employers in New Haven should do.”

Mason said that since the deal with Winstanley, New Haven Works has started negotiating six new partnerships with developers on building projects. 

“101 College represents a vision for our city,” Mason said. “It will produce tax revenue, cutting-edge research and good jobs. But it's also pushing our city to be better organized and coordinated to ensure that the opportunities generated by these biotech projects are widely shared.”
