Top 10 Building Conversions

The conversions of many former commercial buildilngs into New York City apartment buidligns has been a substantial slice of the development pie in Manhattan and nortwestern Brooklyn for a generation or so as climbing rents justified the high architectural, construction and legal costs of changing a structure's usage.  Most of the Top 10 Building Conversions happened a few years ago as the choicest properties were obviously the first to go.  The most recent and glamorous conversion has been the Plaza Hotel on Fifth Avenue at Central Park South where about half the fabled hotel rooms facing Central Park were converted to luxury residential condominiums.

#1 - The Plaza, 1 Central Park South

Condo in Midtown West

The city's most famous luxury hotel, which was designed in French Renaissance chateau-style by Henry Janeway Hardenbergh in 1907, was acquired  by El Ad properties and reopened in 2008 after being closed for about years with 181 luxury condominium apartments facing Central Park and Fifth Avenue and 282 hotel rooms facing 58th Street.
