230 Park Avenue

A New York City landmark, 230 Park Avenue was Gotham’s first pre–war office building to achieve Gold certification under LEED for Existing Buildings.

Designed in 1929 by Warren and Wetmore – the same firm that executed the adjacent Grand Central Terminal – 230 Park Avenue is a 1.4 million-square-foot Beaux-Arts landmark located at East 45th Street and Park Avenue.

Monday Properties purchased the 34-story tower in 2007 and has simultaneously maintained its magnificent pre-war design while updating its building systems and technologies. Indeed, 230 Park Avenue was the first pre-war office building in New York City to earn a Gold rating from USGBC under the LEED for Existing Buildings rating system.

High efficiency air filters, a green cleaning program, and other preventative maintenance initiatives supported the property’s LEED certification efforts, which strived to ensure that, moving forward, 230 Park Avenue minimizes its carbon footprint while still embracing the architectural grandeur of its historic past.
