204 East 47th Street — The Diplomat — is a postwar tan-brick condominium in Turtle Bay, converted from a rental to condominium ownership in 1985. The building spans 204–210 East 47th Street and is generally marketed under the 210 address, which is why the 204 number shows little independent sales presence.
Its architecture is distinctly of its era: an angled east wall, a driveway plaza set-back, corner windows, and terraces on some lines, wrapped in a marble lobby. The location places residents near Grand Central, the United Nations, and the Midtown business core.

Facade safety — Local Law 11

The retrade record

Full closing history with price-per-square-foot over time, the complete retrade record, and every line that has traded.
Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01320-7503) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.
