205 East 85th Street (The Brompton)

The building masses 20 stories along Third Avenue with setbacks at two levels that produce a run of terraces, and a southern portion cantilevered over the low-rise corner building at Third and 85th. Behind the street walls sit two landscaped interior courtyards; the lobby is cherry-paneled with marble floors. The residential program is large-unit-weighted for the corridor: studios from roughly 550 square feet through two- and three-bedrooms to combined four- and five-bedroom units, with penthouse-tier residences carrying fireplaces, terraces, and staff rooms. Finishes from the original sponsor specification — Sub-Zero, Viking, Miele kitchens; six-foot soaking tubs; floor-to-ceiling glass on principal exposures — have been upgraded unit by unit since. Upper floors clear the surrounding mid-rise fabric to open city views in most directions.

Full-service condominium: 24-hour doorman and concierge, live-in resident manager, children's playroom with outdoor play area, residents' lounge opening to a garden, roof deck, bike room, cold storage, private storage, and an event room. The Equinox club within the building's commercial base is the signature amenity adjacency — access arrangements should be confirmed with the managing agent, as terms have varied over time. In-unit washer/dryers run throughout. The offering plan and by-laws are on file in The Roebling Research Library and available to clients during diligence.

Recent sales

Recent closings at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026 to date) cleared a median $1,672/sf (floor-adjusted) across 6 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 3.5% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01531-7501; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. 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.

You are buying the corridor's traditionalist benchmark. Stern's brick-and-cast-stone envelope is the closest thing Yorkville has to a pre-war trophy in condominium form. Against the Lucida's glass and the newer towers north and east, the Brompton's premium has proven durable across cycles — underwrite it as the established standard, not a fashion bet.

Condo mechanics widen the field. No board interview, condominium transfer rules, and a building accustomed to trusts, pieds-à-terre, and international ownership. Confirm current application procedures and any building-specific fees with the managing agent; the by-laws are on file with us.

The transit stack is the location thesis. The 4/5/6 at 86th and Lexington one block west, the Q at 86th and Second two blocks east — few Upper East Side buildings sit between two express-corridor options. Buyers comparing against Carnegie Hill or far-east Yorkville product should price the commute differential honestly.

Check the line for light and the setback map for terraces. The two setback levels create the building's outdoor-space inventory, and the cantilevered southern exposures behave differently from the Third Avenue fronts. Same-line history matters more than building averages here.

Verify the fee stack at offer stage. Working capital contributions, transfer fees, and current Equinox access terms should all be confirmed against the by-laws and managing agent before contract. Run the Mansion Tax Calculator at your intended price — nearly every family-sized unit in the building crosses multiple thresholds.

Market the architecture by name. Robert A.M. Stern's authorship is a documented, searchable asset that distinguishes this building from every other Yorkville condo of its vintage. Pair it with the LEED Silver certification and the building's resale record rather than generic luxury language.

Anchor to Brompton comps, not Yorkville comps. The building consistently outperforms the neighborhood's per-foot averages; pricing off broader Yorkville data understates the asset. Same-line and same-tier history — which we maintain in the Research Library — is the right anchor.

Condition and outdoor space drive the spread. Sponsor-finish units now compete against a deep bench of renovated resales; terraced setback units carry a distinct premium. Document any upgrades against the original spec.

If you're considering 205 East 85th Street, also evaluate:

• 200 East 83rd Street — Robert A.M. Stern's newer Yorkville tower; the direct step-up at materially higher pricing
• The Lucida (151 East 85th Street) — the glass Extell condominium built simultaneously one block west; the modernist side of the same trade
• 180 East 88th Street — boutique new-development condo with dramatic ceiling heights; the design-forward alternative

• Citizen360 (360 East 89th Street) — the contemporary mid-priced Yorkville condo comparison
• One Carnegie Hill (215 East 96th Street) — the value-tier full-amenity condop north of the corridor; apartments trade as co-op shares within a condominium
• 20 East End Avenue — Robert A.M. Stern's limestone East End Avenue condo; the same architect at the corridor's top price point
• The Wales (1295 Madison Avenue) — converted Carnegie Hill alternative for buyers trading west
