345 Park Avenue

345 Park Avenue is a steel office tower rising 193 meters with 44 floors and a white exterior, positioned between Park Avenue and Lexington Avenue at 51st Street. The building connects through the neighborhood's pedestrian walkways and provides underground parking for 150 vehicles.

The building was completed in 1969 by architects Emery Roth & Sons, replacing the former Hotel Ambassador which operated from 1921 to 1966. Its construction marked the area's shift from a luxury hotel to a modern office complex in Midtown Manhattan.

The building holds its own postal code, 10154, making it one of just 41 Manhattan structures with this distinction. This designation reflects its status as a standalone address within the city.

The building is accessible by subway and streetcar lines that stop nearby, with convenient connections to Grand Central Terminal. The surrounding area is well marked with pedestrian pathways that make exploring Midtown straightforward.

Major corporations including KPMG have maintained offices here since the building's opening, while Blackstone Group now occupies over 1 million square feet. The tenant roster shows how the location became a preferred address for international financial and consulting firms.
