RAMSA's residential practice has expanded to include high-rise residential buildings around the world. Beginning with a rental building for Related, Tribeca Park, the firm designed the Chatham in 2001, also for Related, followed by others for Related in New York, Los Angeles, Boston, and Chicago.
Perhaps one of the firm's most well-known residential buildings is 15 Central Park West, located on the southwest corner of Central Park. This limestone-clad building, completed in 2008, set records in New York for the most expensive apartment sale and achieved over $2 billion in total sales. Designed for Zeckendorf Development, 15 Central Park West began RAMSA's relationship with the developer and has led to other work with the company, including 18 Gramercy Park South, completed in 2012 and 520 Park Avenue, currently under construction.
