“We believe they were attracted to the quality of the building and its proximity to the entire Upper East Side. 87th and Third is the center location between the East River, Central Park, and points north and south, with the added benefit of being 1 block from the 4, 5 and 6 line and close to or on several bus routes.” said Jason Muss, a principal of Muss Development. “The building is also one of the very few Class A options on the Upper East Side and it is owner managed, with an owner presence in the building.”

Muss Development was represented by in-house broker and senior vice president Ross Spitalnick. Mount Sinai had a team consisting of Tom Ahn of real estate and Glenn Dawson, a real estate asset manager, representing them in the lease deal.

The building, constructed in 1915 and renovated in 1989, spans six stories and nearly 80,000 square feet. The building is 97% occupied with a few spaces available on the third and fourth floor spanning 1,100 to 3,000 square feet.

Mount Sinai Heart, found in 2006, combines Mount Sinai School of Medicine and Mount Sinai Hospital and is one of the world’s leading centers for cardiovascular medicine and advanced diagnostic therapeutic technologies.
