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 — was conceived to add "some real drama" to a neighborhood of cast-iron lofts, and it does.
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 financing is flexible, there is no co-op board, and pied-à-terre and investor ownership are customary.
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, the building offers the ownership latitude buyers expect — flexible financing, a right-of-first-refusal in place of a board package, and customary acceptance of pied-à-terre, LLC, trust, and investor purchases. Pets are generally permitted. 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.

Facade safety — Local Law 11
An active hazard: the building must keep a sidewalk shed up and make repairs now — expect construction, disruption, and a likely special assessment. We’d get you the repair scope and the building’s funding plan up front, so you go in knowing exactly what’s underway and what it’s likely to cost.

With just 55 residences, 35XV trades thinly — typically a small handful of resales in a given year across the one- to four-bedroom range. Pricing sits in the upper tier of the Flatiron–Union Square condominium market and is driven by floor, exposure, layout, and renovation, with the higher floors and their open skyline views commanding the strongest figures. Inventory scarcity means a single listing can reset the building's comparable. For current availability and a unit-level read, the live sales record for this address is the place to begin.
What to know if you’re buying
The condominium structure is the headline advantage over the surrounding co-op and loft stock: a right-of-first-refusal rather than a board interview, flexible financing, and no bar to pied-à-terre or investor ownership. 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 on a faster, more predictable timeline than a co-op — itself a point worth making to buyers — and staging to the home's light and skyline exposure plays directly to the building's strength.
