2025 Power 25 Real Estate: Adam Winstanley

Massachusetts-based developer Winstanley Enterprises, under the leadership of Adam Winstanley, for years has been a leading force in logistics development north of Hartford.

The company shows no signs of slowing down, with several projects lined up, including a massive development planned on the eastern edge of the state.

Adam Winstanley is a principal of Winstanley Enterprises, leading its industrial development efforts. His brother, Carter Winstanley, has led the firm’s successful push into developing lab and office space for New Haven’s bioscience sector.

In late April, Winstanley Enterprises sold a roughly 200-acre Enfield property, at 35 Bacon Road, to e-commerce giant Amazon for $20 million. Winstanley had secured local approvals for an 819,000-square-foot warehouse on the site.

Amazon has not yet revealed the size of the logistics building it plans to erect on the property. Adam confirmed his company has been engaged to coordinate the construction, a project he expects to launch next year.

Separately, Adam said he plans to launch this summer construction of a 420,000-square-foot warehouse on a 133.6-acre Enfield site. The company purchased 1679 King St. for $4.6 million in 2023. Adam estimates building costs of about $80 million, and an 18-month construction schedule.

Adam said he has a tenant for the building, but declined to identify the company.

Winstanley Enterprises also plans to spend much of this year seeking permits to build a 1-million-square-foot-plus warehouse in Killingly. The project, with an estimated price tag of more than $200 million, will be built on 600 acres.

Adam said he has an undisclosed tenant lined up for the building that will employ more than 500 people.

“I love the town of Killingly, they are a very pro-business community,” Adam said.
