Mount Sinai Health System announced on Tuesday that phase one of a $500 million project to rebuild Mount Sinai Beth Israel and create the new “Mount Sinai Downtown” network is set to start. The network will expand and renovate three sites of outpatient facilities, according to the hospital, which will stretch from the East River to the Hudson River below 34th Street. The network will include 35 operating and procedure rooms and 16 physician practice locations with more than 600 doctors.

On a far-eastern block of the Upper East Side’s Lenox Hill neighborhood, a unique venture is underway to build new facilities for Hunter College and Memorial Sloan-Kettering Cancer Center. Now wrapping up its cavernous foundations, the 1.15 million-square-foot development will accommodate two separate towers: an East River-facing building that will house a 730,000-square-foot, 23-story outpatient treatment center for Memorial Sloan-Kettering; and a slightly smaller, 400,000-square-foot mid-block building for CUNY-Hunter College’s schools of nursing and physical therapy. Hunter will trade its current nursing school facility at First Avenue and East 25th Street to the city where they will build a new sanitation facility.

In 2012, then-mayor Michael Bloomberg awarded the institutions the right to to build upon the half-block parcel fronting the FDR Drive between East 73rd and 74th Streets. The site was previously home to a sanitation facility that was demolished in 2008 and was sold to the college-hospital for $226 million. The mammoth, 455-foot-tall structure is being designed by Perkins Eastman in collaboration with Ennead Architects and required special approvals to rise more than the as-of-right floor area and height limit. Aside from the project’s size, neighbors took issue with the project’s shortfall of parking spaces and the resulting congestion of a community loaded with medical facilities.
