New MOB in New York to Deliver 400,000-SF Class A Office Space

A 30-story medical office building in the Yorkville section of Manhattan’s Upper East Side recently topped out. Developed by Extell Development Company, the 400,000-square-foot facility, slated for completion in 2025, will house doctors’ offices, medical treatment centers and retail space on the ground floor.

Lendlease provided pre-construction services ahead of the tower’s groundbreaking and is serving as construction manager for the development, which is being built on a full-block site located on the east side of First Avenue, between East 79th and East 80th streets. It offers proximity to some of the city’s top hospitals and medical research centers.

The Hospital for Special Surgery has signed on as anchor tenant and will occupy 200,000 square feet across the first eight stories. Additionally, the building will offer accommodations for both Department of Health and Article 28 requirements for uses such as ambulatory care and surgical facilities.

Upon completion, 1520 First Avenue will feature the latest in modern, user-centered design, infrastructure and technological specifications. In addition to oversized windows that will offer expansive views and an abundance of natural light, the building will incorporate post-COVID enhancements and specific healthcare solutions, including increased ventilation and enhanced filtration.

Designed by Perkins Eastman, the MOB comprises a rectangular tower atop a multistory podium with numerous setbacks. The façade utilizes white paneling to form a grid of vertical window groupings, while the crown will feature dark metal grilles. WSP is serving as the structural engineer of record.

The building uses a system that incorporates pre-assembled voids inside the reinforced concrete slab, allowing for larger column-to-column spans, while reducing overall concrete consumption of the project. With this system, a high proportion of the solid slab’s concrete is replaced by void formers that consist of 100% recycled plastic, supporting the contractor’s sustainability goals.
