4 East 88th Street is the Guggenheim-facing Georgian Revival cooperative — a 1922 boutique 34-35-unit building directly across the street from Frank Lloyd Wright's Solomon R. Guggenheim Museum (1959). That Guggenheim-facing position is the defining one: every front apartment looks directly onto Wright's Museum and the Frank Lloyd Wright sculpture garden, an outlook no other Carnegie Hill cross-street co-op can match. Behind it stands a Georgian Revival composition in red brick, with a "pleasant and bright lobby with an attractive black-and-white marble floor" per public records. Rounding out the appeal is a flexible policy framework — 65% financing, a 2% flip tax, welcomed pets, and permitted pied-à-terre, subletting, gifting, and guarantors, all with board approval — that makes this one of the more accommodating boutique buyer profiles in the neighborhood.

Facade safety — Local Law 11

The retrade record
Lines that have traded more than once in the public record — the building’s appreciation arc, apartment by apartment.
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 1-01499-0065) 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 on co-ops is not officially recorded, figures shown are approximate.
What to know if you’re buying
The Guggenheim-facing position is structurally distinguishing. No other Carnegie Hill cross-street cooperative carries the same exposure.
The flexible policy framework — 65% financing, 2% flip tax, welcomed pets, permitted pied-à-terre, subletting, gifting, guarantors — produces one of the more accommodating boutique Carnegie Hill buyer profiles.
The boutique 34-35-unit scale supports operational intimacy. Plan board diligence accordingly.
The Georgian Revival architectural composition with the black-and-white marble lobby anchors the institutional identity.
The reserved amenity layer — no garage, no health club, no sundeck — should be evaluated against buyer expectations.
Closing timelines are cooperative-standard. Plan for 6 to 10 weeks from contract through board approval to closing.
