Connolly Brothers' corporate headquarters are located at 152 Conant Street in Beverly, Mass. Connolly purchased and developed the land for this first-class office building, which hosts several other corporate tenants.

Connolly handled project development, preconstruction, design coordination, and construction management work on the 75,000 square-foot space, and collaborated with Sullivan Design Group, the project's architect. The building's exterior abuts Route 128, providing easy access to and from Boston, and its interior features an inviting atrium that balances sleek design with welcoming trees and plants, making it an ideal home on the North Shore for a variety of businesses and professionals.
