A Private Pricing Opinion — what your apartment at 35XV would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
35XV is one of the more architecturally distinctive condominiums to rise in the Flatiron–Union Square corridor in the last generation, and it owes its existence to one of the cleverest deals in modern New York development. Alchemy Properties assembled the air rights of the adjacent Xavier High School and stacked a 55-unit luxury condominium directly above the Jesuit school — a transaction so unusual it took the Real Estate Board of New York's award for the most ingenious deal of the year. The school occupies the granite-clad lower floors; the residences begin roughly a hundred feet above the street, with the building rising as a faceted glass-and-stone tower designed by FXFOWLE.
That stacking arrangement is the building's defining trait and its quiet advantage. Because the residential floors start so high, even the lower apartments read like mid-rise homes, with open light and long views over the low-rise blocks of the Flatiron and Chelsea grid. The architecture — a clean, linear, glass-forward expression set on a heavy stone base — contrasts with the surrounding cast-iron loft buildings.
For buyers, the case is straightforward: a modern condominium in a small, design-led building at the geographic center of downtown's best walking. This is a condominium, so there is no co-op board admission, and pied-à-terre use is permitted; confirm financing, leasing and ownership-entity rules in the current declaration, bylaws and house rules.
Architecture and unit composition
The building's silhouette is deliberate: a solid granite plinth — the school — supporting a crystalline residential tower whose facade folds and faceted glazing catch light across the day. FXFOWLE's design pairs floor-to-ceiling windows with a stone-and-glass envelope that gives the building more weight and texture than a plain curtain wall.
The 55 residences span one- to four-bedroom layouts, many with ceiling heights around ten feet and the open, light-filled proportions the elevated base makes possible. Interiors carry a restrained, contemporary finish program with clean detailing throughout. The mix runs from efficient one-bedrooms to large four-bedroom homes near the top, and the upper floors capture the building's best light and skyline exposures.
Building operations
35XV operates as a full-service condominium with a 24-hour doorman, concierge service, and a resident manager. The amenity suite is unusually complete for a 55-unit building: a fitness center that opens onto a 75-foot-wide common outdoor terrace, an entertainment lounge, a private dining room, a wine cellar, a children's playroom, bicycle storage, and private storage units.
As a condominium, there is no co-op board admission; purchases run through the condominium's application and right-of-first-refusal process, and pied-à-terre use is permitted. Confirm financing, leasing, ownership-entity and pet rules in the current declaration, bylaws and house rules. Common charges and real estate taxes are billed separately, and the building's central Flatiron position keeps every form of downtown transit, dining, and retail within a few blocks.
Sublet and pied-à-terre policy
A condominium owner leasing a unit and a co-op shareholder subletting are different rules, and a building-wide rule is different from a restriction on one apartment. This is the building's rule; confirm it for the specific apartment.

Common charges plus real estate taxes, combined into one monthly figure the way New York condominium listings show them. Add a mortgage payment for the monthly outlay. The split into common charges and taxes comes from the listings that also give the annual tax, a different sample, so the two lines need not add up exactly to the combined median; a tax abatement can hold taxes below the full amount until it expires. A summary of recorded sales and listings, not a current bill; charges change.

The latest available filing classified the facade as Unsafe — conditions requiring prompt corrective action. The owner must install any public protection the inspector specifies (a sidewalk shed, construction fence or structural netting, depending on the condition) and make the repairs. Review the subsequent filings, the repair status, and the building’s board and financial materials — we pull the repair scope and funding picture for you.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

421-a Tax Abatement

- Fully taxed from
- FY2027 (2026–27)
- Program
- 421-a (10-year)
The 421-a benefit has run its term, so taxes on these units have stepped up toward the full assessed amount. Get the current tax bill for the specific apartment and compare its tax component with any older listing: an earlier carrying-cost figure may reflect the benefit, or different common charges and assessments. Treat a comparable sale made while the abatement was still running as priced under different taxes.

Years shown are NYC tax years, which start July 1 — FY2027 runs July 1, 2026 to June 30, 2027. The benefit last appears on the 2026 assessment roll, which is what dates the end of the term.

Market read. Most recent trades (2026 to date) cleared a median $2,044/sf (floor-adjusted) across 5 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 0.0% from the last ask.

What to know if you’re buying
The condominium structure is the headline: a right-of-first-refusal rather than a co-op board interview, with pied-à-terre use permitted; confirm financing and leasing rules in the governing documents. Diligence here should focus on floor and exposure — because the residential floors begin so high, light and views improve meaningfully as you rise — and on the layout, since the unit mix ranges widely. Review the building's financials and reserve position; an amenity-rich building this size carries real operating costs. The location is among the most walkable in Manhattan, with the convergence of Flatiron, Union Square, Chelsea, and the Village transit and retail all within easy reach.
What to know if you’re selling
Lead with the building's genuine differentiators: a FXFOWLE-designed glass-and-stone tower, residences elevated a full hundred feet above the street for light and views, a deep amenity package including the 75-foot terrace, and the flexibility of condominium ownership. Benchmark to comparable Flatiron and Union Square new-construction condominiums rather than to neighborhood lofts or co-ops. A resale clears through a right-of-first-refusal and staging to the home's light and skyline exposure plays directly to the building's strength.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
