Extell's Park Avenue Assemblage Gets $286.8M JPMorgan Loan

Four affiliates of Extell Development Company recorded a $286,763,593.51 building loan agreement with JPMorgan Chase Bank on August 17, 2026, pledging five contiguous Manhattan lots along Park Avenue and East 55th and East 56th Streets as collateral, according to the document detail record filed with the New York City Register. The borrowing entities, 407 Park Avenue LLC, 57 East 55th Street LLC, 165 East 56th Street LLC and 110 E 55 LLC, each list Extell’s 805 Third Avenue offices as their address, and each was assigned to a single lot in the assemblage: 405 and 407 Park Avenue, 57 East 55th Street, 165 East 56th Street and 110 East 55th Street.

Why it matters

A building loan agreement recorded across four single-purpose entities and five adjoining lots is the financing step that typically follows a site assembly, not a groundbreaking. Extell, led by Gary Barnett, now controls a merged Plaza District parcel spanning both sides of the Park Avenue and East 55th-56th corridor, and the recorded loan gives the first verified dollar figure on the capital JPMorgan has committed against it. For developers watching the Park Avenue corridor, the filing confirms the assemblage is financed and consolidated under one lender rather than sitting as separately mortgaged lots, which is usually the signal that entitlement and design work, not further land assembly, is the next visible step. Our New York desk is tracking the corridor alongside today’s Herald Square hotel demolition permit as two of Manhattan’s active site-assembly stories this week.

The numbers

The agreement’s own document date is July 31, 2026, but the City Register did not record and file it until August 17, 2026, at 2:56:19 PM, a gap of more than two weeks between signing and recording that outside summaries citing only the recording date have missed. The instrument runs 51 pages under CRFN 2026000231891 and cross-references three earlier recorded documents (CRFNs 2026000135380, 2026000136115 and 2026000143777), which correspond to the separate transactions that originally brought the four lots under Extell’s control before this loan tied them together. Of the five parcels, two are recorded as non-residential vacant land (405 and 407 Park Avenue) and three as commercial real estate (57 East 55th, 165 East 56th and 110 East 55th Streets), all in Manhattan.

What’s next

No construction or new-building permit has yet been filed against any of the five lots under this loan, so the next verifiable milestone is a Department of Buildings application naming a combined footprint or a specific building program. A building loan agreement of this size against a freshly merged site is typically followed by a foundation or superstructure filing within one to two years once design and approvals are in hand; until a permit is filed, any claim about unit count, height or use at the site remains unverified and this desk will not print one. We will track DOB filings against these five block-and-lot numbers, 1-1309-1, 1-1309-69, 1-1291-127, 1-1311-33 and 1-1309-66, for the next filing tied to the assemblage.
