And few have capitalized on the growing industry like David Winstanley and his sons, Adam and Carter. Owners of the family-run realty shop, Winstanley Enterprises LLC, the Massachusetts-based firm is Connecticut’s largest owner of warehouses. The family, which has offices in Hartford, New Haven and Bristol, solidified its local prowess in 2020 by buying J.C. Penney’s former Manchester distribution center and spending $44 million on a pair of abutting food distribution and storage facilities in South Windsor. This spring, Winstanley plans to kick off construction on a $100 million bioscience tower in New Haven that will add another 500,000 square feet of laboratory and life-sciences incubation space in the Elm City.
