    Less than two months after the groundbreaking of its new building, currently being constructed at 100 College Street, Alexion plans to expand, adding an additional two floors of space

    (New Haven, CT) The City of New Haven is pleased to announce that Alexion Pharmaceuticals, the main tenant for the 100 College Street project at New Haven’s Downtown Crossing, has asked developer Winstanley Enterprises to modify plans to include an additional two stories of space, expanding the total square footage by 76,464 square feet..

    “This expansion is good news for the city and indicative of the tremendous growth the company has seen in recent years and their commitment to New Haven,” said Mayor John DeStefano. This expansion will further position our city as a leader in bioscience industries creating good jobs for our residents.”

    The Development Agreement approved by the Board of Aldermen was written to accommodate such an expansion. The minimum required by the agreement was a lab/office building of 225,000 square feet in size. The building, as presented to the Board of Aldermen, was approximately 425,000 square feet and 10 stories in height. This new addition will bring the building to 12 stories and total space to approximately 500,000 square feet, still under the permitted maximum square footage permitted by zoning . To put this in perspective, the height of the building will still be less than the height of Smilow Cancer Hospital and the overall square footage will be about 25,000 square feet less than the 300 George St building next door.

    The state-of-the-art 12-story office building is the first building to be erected as part of New Haven’s Downtown Crossing urban revitalization effort. Downtown Crossing is the largest infrastructure activity in New Haven in decades, and is funded by the U.S. Department of Transportation’s TIGER II grant, the city of New Haven and the State of Connecticut. It is expected to create 2,000 construction jobs, result in $184 million in direct and indirect spending over the next three years, and create 900 permanent jobs upon completion. The building is being constructed to be certifiable to an environmental standard of at least LEED Silver.

    When Alexion takes occupancy in 2015, it will mark the company’s return to the city where it was founded more than 20 years ago. Alexion plans to relocate more than 400 employees who are currently based in Connecticut to the new site in 2015 in addition to adding between 100 and 200 new employees.

    “What is also exciting is that city staff have received inquiries concerning housing opportunities for Alexion employees to move into the city once they take occupancy of the building,” said Kelly Murphy, New Haven Economic Development Administrator. “This points to a highly successful company, looking to expand rapidly and grow jobs in a city full of vitality and opportunity.”
