Proven Success

Life Science

100 College Street

100 College Street was a $200 million, 513,000 square foot development that represented the first modern life-science building in New Haven.

  • At the time of construction, 100 College Street was Alexion Pharmaceutical’s (now part of AstraZeneca) new worldwide headquarters. The property is now fully leased to Alexion and Yale University.
  • The building helped jump-start the life-science industry in New Haven and the State of Connecticut. The property’s success led to the current development of 101 College Street, a $250 million, 525,000 square foot life-science building expected to be completed in Summer 2023.
  • Winstanley designed and constructed the 14-story office/laboratory building, complete with a rooftop garden and an 850-space parking garage, that meets certification under the Leadership in Energy and Environmental Design (“LEED”) to a Silver Standard level.
Logistics & Distribution

Logistics Portfolio

The Logistics Portfolio is a 7.2 million square foot massing of modern warehouse, distribution, and light industrial facilities located primarily in central Connecticut and Massachusetts.

  • Winstanley acquired the bulk of the value-add portfolio in January 2017 and has since acquired additional institutional-quality logistics assets, becoming one of New England’s largest warehouse landlords.
  • Through our deep redevelopment experience and leveraging our years of tenant relationships, Winstanley was able to achieve 100% occupancy with Blue Chip tenants including Amazon, Home Depot, Stop & Shop, Lego, Advanced Auto Parts, and Coca Cola.
  • Winstanley has been at the forefront of building a prime warehouse portfolio in central Connecticut and Massachusetts where surging demand has occurred due to compressed delivery time-frames.

Page Field Commons

Page Field Commons is a best- in-class, 320,000 square foot, multi-anchored retail center that is now considered Southwest Florida’s dominant power center.

  • Over that past four years, Winstanley has diligently put in place the region’s best retail anchor lineup and has taken the property from 78% occupancy to 98%. Major Tenants include Trader Joe’s, Dick’s Sporting Goods, Best Buy, Ross, and Marshalls.
  • With the property at full occupancy with 92% of revenue coming from national tenants, Winstanley has been able to almost double the valuation of the property from our original purchase price.
  • In order to attract tenants, Winstanley has spent millions of dollars upgrading the property’s parking.

Grist Mill

Grist Mill is a 32-unit high-end condo development with an underground parking garage. The project was fully pre-sold before construction was completed.

  • Grist Mill Chelmsford is a new four-story condominium community located near Chelmsford’s vibrant town center. The units feature two bedrooms and two bathrooms with luxe finishes, a patio, and covered parking below.
  • The units range in size from 1,400 to 1,800 square fee and were sold at an average sales price of $505,000.
