Our Story







Our Story

Maurice H. Kouffman, a pilot and veteran of World War II, settled in East Hampton in 1958 after living in Israel and helping to found El Al Israel Airlines. In East Hampton he continued to live as a visionary, this time through construction and real estate. His first project was the Star Lanes bowling alley, and his achievements include some of East Hampton’s most iconic landmarks –The East Hampton Cinema, The East Hampton House, and the fashionable 66 Newtown Lane complex. 


founded in 1960 by Maurice h. Kouffman.

  • 1960 - FOUNDING

    After moving to East Hampton with his family, Maurice H. Kouffman begins the company with a few very notable commercial builds.


    In 1977, Phillip D. Kouffman joins his father overseeing day-to-day operations, and spearheads the company’s growth into high-end residential construction.

  • 2000's - A REAL ESTATE BOOM

    In the 1990's people thought the Hamptons couldn't get any bigger. Then the 2000's happened. With record real estate sales and a trend towards larger more complex builds, the company tripled its production.


    "Our policy is, and has always been, client first!" Our family is truly proud of its heritage and commitment to the East End, and we look forward to the many exciting projects that lie ahead.
