The Wilmington Club HVAC Upgrade

The Wilmington Club, also known as the John Merrick House, is a historic clubhouse designed by architect Edmund George Lind and built in 1864 as a three-story, five bay “T”-plan brownstone dwelling in the Italianate style. The Wilmington Club purchased the building in 1900 and expanded it several times. The Building is listed in the National Register of Historic Places.

DEDC has recently completed HVAC upgrade projects for the Wilmington Club. The projects included HVAC, electrical and structural engineering, and design.

The need for our design to seamlessly integrate with this historic building was very challenging and was a critical success-factor for the project.

The DuPont Building was recently purchased by a developer and is undergoing a significant renovation. DEDC is part of the project design team with responsibility to provide engineering and design to update the building MEP infrastructure and common spaces.
