Constance recently completed various interior renovations at a private high school in Queens and is now working on a two story expansion which includes a new Music Wing. She is also working on a 6,500 sq ft Wellness and Fitness Center in NYC.

Constance’s involvement encompasses all aspects of the project, from initial concept to design through final construction documents and permitting. She works with experts in various disciplines to make sure the right building system is chosen and stays up to date on the latest building materials and codes.
