Continuum Company is a privately held real estate development company. It was founded by Ian Bruce Eichner in 1981, and today its core holdings are in office, hospitality, and retail space in New York City, Miami, and Las Vegas. The company faced a lull in the 1900s, losing ownership of several of its buildings to competitors or bankruptcy (among them the CitySpire Center, 1540 Broadway, and the Cosmopolitan of Las Vegas). However, it also helped transform parts of the city, such as turning a bankrupt hotel near Central Park into a timeshare hotel dubbed the Manhattan Club. The company also helped bring the first high-rise in decades to Brooklyn Heights. In recent years the company has made a comeback, filing permits to develop more than 1 million square feet of property in 2013. In 2015, Continuum began to develop the 65-story luxury condominium building at 45 East 22ndStreet, which is scheduled for completion in 2017.
