11 Sutton Place North, Manhattan

I.M. Pei lived here for 46 years. The trust sold it in 2021 — and almost nothing has shown up on the city's record since.

11 Sutton Place is an 1899 single-family townhouse a half-block off the East River. The architect of the Louvre Pyramid and the JFK Library bought it in 1973 and held it until his death in 2019. Two years later his trust sold it to Gardner Tompkins LLC for $8.6M — the first arms-length transfer in 48 years. Two things to know:

One owner for nearly half a century. Five decades of single-family occupancy by one architect means whatever interior work was done is largely undocumented in the DOB record — Pei did not file routinely. Anything still standing from his era is unphotographed and unprotected unless the current owner has chosen to preserve it.

One closed 311 complaint, October 2023 — two years after the LLC took title. The only 311 call on this address since the sale. Asbestos complaints two years after a townhouse changes hands typically signal demolition or gut-renovation prep. Nothing else on the permit record explains it, which means either the work is happening below the DOB-permit threshold or it hasn't formally started.

33 encampment calls in the last 12 months — not cooling off. The 59th St Bridge on-ramp is two blocks north and it's still active on the 311 record — most recent encampment call April 28, 2026. Last fall it looked like the cluster was thinning; the 12-month rolling count says otherwise. This is a street-condition read on the corridor, not on the house itself, but it's the ambient noise you'd be buying into.

Quieter signals on this building and the blocks around it:

• A 2010 DOB violation for the private residential elevator — dismissed. Confirms there's an elevator in the house.
• Gardner Tompkins LLC is the only thing on title since 2021. Generic-shape Delaware name; the human owner isn't in the public record.
• FHV driver-loitering is slowing but present — 20 calls in the last 12 months, most recent April 25. Same bridge-approach story as the encampments.
• Blocked hydrants on the corner are chronic — 21 calls in the last year, most recent May 16, 2026.
