Memorial Sloan Kettering filed plans Tuesday to build on York Avenue a 600-foot tower they say will better allow them to provide superior treatment to cancer patients who need complex care, city records show.
The proposed MSK Pavilion would replace medical student housing and administrative offices at 1233 York Ave., near East 66th Street, with a 31-story complex, according to newly filed zoning documents.
If approved, the pavilion will total nearly 1 million square feet, with 28 operating suites and 202 inpatient beds, according to zoning documents.
Plans also include a skybridge across East 67th Street to connect the pavilion to MSK’s main hospital, according to plans contingent on Transportation department approval.
The plans would also require rezoning approvals on York Avenue to allow for the size of the new building.
If approved, the new pavilion would expand Memorial Sloan Kettering’s already substantial presence in the neighborhood.
The world-renowned cancer center has eight facilities on the Upper East Side, not including its main York Avenue campus, which the new pavilion would join.
Memorial Sloan Kettering’s most recent expansion was the David H. Koch Center for Cancer Care, a distinctive 25-story facility completed in 2020, facing the East River between East 73rd and 74th streets.
In January, the hospital laid off more than 300 workers in response to poor economic outlooks.
The hospital will present its plans to the Community Board 8 Zoning Committee on Tuesday evening.
LOL, NIMBYs are going to have meltdowns. Hopefully its a nice design, MSK can afford it.
Very nice.

20 minute onward for the details.

If you go to the 1 hour and 56 minute and 50 second mark in the CB8 stream, its already begun.
“a lot of environmental studies about the adverse impact of buildings over 200 ft”
This will be the tallest tower on the UES. This will likely be chopped down. Hopefully not. Let’s see how it goes. We know how it went with Lenox hill, they scrapped an entire tower out of their development plan. 
Memorial Sloan Kettering Cancer Center presented their proposal Tuesday night to finally build a new hospital building that was in the works over 20 years ago, until the September 11 terror attacks forced them to shelve their plans.
On Tuesday, the hospital filed the proposal, first announced a year ago, to build a 31-story, 600-foot hospital on York Avenue between East 66th and 67th Streets.
That evening, MSK came before Community Board 8 in an early-stage presentation, which mostly received a warm reception from board members who often made unfavorable comparisons to another large rezoning request from a Lexington Avenue hospital also currently in progress.
If approved, the pavilion will total nearly 1 million square feet, with 28 operating suites and 202 inpatient beds, according to zoning documents.
Plans also include a skybridge across East 67th Street to connect the pavilion to MSK’s main hospital, according to plans contingent on Transportation department approval.
While applauding some aspects of the presentation, members voiced concerns over the size and bulk of the proposed building as well as worries that the demolition of a MSK-owned, 336-unit residential building currently at the site would add pressure to an already historically tight housing market in the neighborhood.
