335 Madison Avenue
335 Madison Avenue is a repositioned Class A office tower located directly adjacent to Grand Central Terminal, offering one of the most transit-integrated office experiences in Midtown Manhattan. Formerly known as the New York Biltmore Hotel site, the building has been transformed into a modern, amenity-rich office environment that blends scale, infrastructure, and immediate access to regional transit.
Rising approximately 42 stories, the property contains roughly 1.1 million rentable square feet, placing it firmly within the large-scale office tower category while still maintaining flexibility across tenant sizes. Unlike older prewar assets in the immediate area, 335 Madison delivers modernized floor plates and upgraded systems, making it highly competitive with newer Midtown East inventory.
The building is defined by its efficient floor plates, typically ranging from 20,000 to 30,000 square feet, allowing for both full-floor identity and multi-tenant configurations. These layouts support a wide range of users—from mid-sized firms seeking visibility and branding to larger tenants requiring contiguous blocks across multiple floors.
A key differentiator is the building’s direct internal connectivity to Grand Central Terminal, which significantly enhances daily commute efficiency. This feature alone places 335 Madison Avenue in a distinct tier, particularly for tenants with regional employees commuting via Metro-North or Long Island Rail Road.
The property has undergone extensive capital improvements, including lobby renovations, infrastructure upgrades, and the addition of high-end tenant amenities. These enhancements have repositioned the building into a Class A competitive set, despite its earlier construction origins. Tenants benefit from modern mechanical systems, upgraded elevators, and improved common areas that align with current workplace expectations.
From a design standpoint, 335 Madison Avenue offers a clean, contemporary glass façade with strong window lines, providing consistent natural light across floors. The building’s scale and structure allow for efficient workstation layouts, collaborative environments, and traditional office configurations, depending on tenant needs.
In the context of Midtown East, 335 Madison Avenue competes directly with both legacy towers and newly developed assets by offering a balanced combination of location, infrastructure, and value. It is not a boutique or highly architectural trophy tower; instead, it delivers practical, high-functioning office space with unmatched transit access.
For tenants evaluating office space in Manhattan, 335 Madison Avenue represents a strategically located, transit-driven office solution—ideal for companies prioritizing accessibility, efficient layouts, and a central Midtown presence tied directly to Grand Central.
335 Madison Avenue is a large-scale, full-block Class A office tower engineered for high-capacity tenancy, with infrastructure and floor plate efficiency aligned more with institutional users than boutique occupiers.
