Irving Dimson, his father in-law, Isadore Feldman, and his brother in-law, Harry Feldman, founded Carlyle Construction Corporation in 1946. During the 1940’s and 1950’s, the company’s focus was on the development of garden apartments and single family homes in New York, New Jersey, Ohio and Georgia. In the 1960’s, Carlyle’s focus changed to the development and management of luxury high-rise apartment buildings and commercial properties. Some of the properties developed and managed by Carlyle in Manhattan were Regency Towers, Regency South, Gracie Towne House, Ambassador East and Carlton Towers. Carlyle also developed and managed Harbor Towers in Boston and 4 Penn Center in Philadelphia.
In 1969, Norman Dimson, a Professional Engineer and licensed real estate broker, joined his father in the firm. During the 1970’s and 1980’s the firm continued its development and management of luxury high-rise apartment buildings with the construction of the Wellesley in Manhattan and the redevelopment of two Manhattan hotels into apartment houses (The Dryden East on 39th Street and The Towne House on 38th Street). The firm also redeveloped the Penn Athletic Club in Philadelphia into The Rittenhouse Regency, a mixed use building containing offices, stores and apartments.
In 1984, Norman Dimson became President of Carlyle. During the following eight years, the firm continued to develop luxury apartment buildings including The Forum (in Manhattan) and built two hotels with the Journey’s End Corporation of Canada (one in Manhattan and one in Connecticut). In addition, in 1986, Carlyle acquired a marina in Northport, New York and redeveloped it into The Britannia Yacht and Racquet Club, which contains 310 luxury boat slips, a clubhouse, a swimming pool and shops. Carlyle currently jointly manages this property with its two partners. In 1992, Michael Dimson, a Certified Public Accountant and licensed real estate broker, joined his father in the firm. Michael became Controller of the company and in 1994 became the Vice President and the head of the company’s management division.
