The Association of Roslyn Estates was incorporated in 1911. It is the oldest existing residents' civic association in Nassau County.
The original sales office of Roslyn Estates, Inc., located at the intersection of Intervale and Warner Avenue, was given by the developers to the Association for use as a meeting and polling place. The Association later leased this quaint building as a tea room and restaurant. Over the years, it has had many different tenants. In 2005, it became "Colbeh".
