Overview

This offering is part of Science Park, a mixed-use campus developed through adaptive reuse of the former Winchester Repeating Arms Company manufacturing complex. The space was constructed for a vocational training nonprofit and includes a large commercial kitchen, an operating cafe, classrooms, and office space. The premises are set up across two floors, with the ability to lease the two floors separately, and the second floor space can be divided in half.

The property is immediately north of the Yale campus and within walking distance of the university’s Science Hill research complex. Science Park also provides 24/7/365 staffed security. Parking is available for both employees and visitors, including a visitors lot directly adjacent to the cafe and free employee parking across the campus.

For tenants seeking a turnkey environment for food service operations alongside training or educational programming, the combination of kitchen, cafe, and classroom/office space supports multiple daily uses. The floor-by-floor leasing flexibility and the option to split the second floor can help organizations right-size operations while maintaining dedicated areas for instruction, administration, or food-related activities.
