A Multi-Generational, Family Owned and Operated Real Estate Development Company

Chatham Development Company is a multi-generational, family owned and operated real estate development company. Our primary focus is on residential and mixed-use properties, and development opportunities in New York City and Long Island. We have a broad range of experience and skills spanning development, construction, marketing, and sales of master-planned communities and condominiums, construction of storm-fortified coastal vacation homes, and management of income-producing multi-tenant commercial properties.

When many homebuilders back down from the complex challenges of real estate development, Chatham Development Company rises to the occasion by leveraging the skills and experience of its multi-talented team to analyze each potential opportunity, overcome development hurdles, construct durable and top-quality improvements, and delivery on its investment goals on each project.

Meet the Team

Harvey GessinPresident

Harvey Gessin is President and Founder of Chatham Development Company. Mr. Gessin formed the company in 2002 and has directed the acquisition, development and construction of over 2,000 residences in Long Island and Manhattan since its inception.

Mr. Gessin began his career in 1971 as an electrical contractor undertaking large commercial and residential projects in New York City under the name Gessin Electrical Contractors. In 1982, Mr. Gessin formed Gessin Contracting Company and went on to develop and construct 130 condominium and co-op apartments in Manhattan through the end of the 1987.

In 1989, Mr. Gessin shifted his focus from urban residential development to distressed residential and commercial properties on Long Island, where he partnered with banks and their borrowers to transform non-performing loans and investments into successful development projects. Each of these deals required a unique finesse to strike a win-win-win deal for all parties involved. Between 1989 and 1995, Mr. Gessin successfully completed and sold hundreds of homes in stalled developments and transformed a dilapidated, bankrupt marina into a vibrant waterfront attraction.

Capitalizing on the housing boom of the mid-1990’s and early 2000’s, Mr. Gessin played a lead role in the development, design and construction of more than 600 homes in planned communities, waterfront recreation areas and luxury neighborhoods across Long Island.

Over the past 15 years, Mr. Gessin successfully completed The Chatham at North Hills – a 144-unit townhouse development, Chatham44 – a 58-unit condominium in Manhattan, several custom single family Estates in Kings Point and the development of a number of waterfront homes along Dune Road in Westhampton Beach.

Mr. Gessin’s long-term success can be attributed to his ability to carefully monitor trends and his disciplined approach to risk taking, enabling his projects to weather the worst of markets while remaining profitable.

Mr. Gessin is an active supporter of the Holocaust Memorial and Tolerance Center of Nassau County and serves as the Chairman of the Village of Westhampton Dunes Zoning Board of Appeals.
