Our mission is to provide superior real estate investment returns for our investors, and high-quality leased space for our tenants at or below market rates.

David Winstanley formed Winstanley Associates in 1973. Two decades later, founded on his success in real estate development and investment, David joined forces with his sons, Adam and Carter, to form what is now Winstanley Enterprises. Today, we’ve acquired and developed more than 100 properties comprising more than 12 million square feet.

We have a long history of delivering technically and logistically challenging projects that focus on sustainable neighborhood design and mixed-use development. We specialize in acquiring land and under-performing assets, and through our redevelopment and modernization efforts, create productive assets that provide real benefits to communities.


Experience that speaks for itself.

With 50+ employees across four offices, our in-house asset management, construction management and property management teams have direct oversight and control of all acquisition, development and repositioning activities. We work across a wide range of asset classes including office, laboratory/biotech, industrial, retail, medical office and residential. Our expertise, creativity, and decades-long ties to the states and communities in which we operate contribute mightily to our success.


A hands-on approach.

We’re proud to have established a reputation as a hands-on, service-oriented company. We work closely with tenants and municipalities during every phase of the development process, including feasibility analyses; local, state and federal permitting; architectural and engineering design; and building construction.

Our team has the integrity and experience to deliver on our company commitments to tenants and investors alike. Our strong capital base, agility in decision-making, and strategic alliances give us the competitive edge we need to acquire and reposition properties (often in surprisingly short timeframes) and provide significant capital appreciation for our institutional and equity investors. We work creatively with businesses and municipalities with a participative, straightforward approach.

Full-service, fully integrated.

Winstanley Enterprises and its two operating subsidiaries are vertically aligned to provide our portfolio with a full suite of high-quality services.
