A Private Pricing Opinion — what your apartment at 400 Park Avenue South 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.
400 Park Avenue South is the condominium crown of one of NoMad's most recognizable towers — a faceted, crystalline glass building by the Pritzker Prize–winning architect Christian de Portzamparc that rises 42 stories at the corner of Park Avenue South and East 28th Street. The tower is mixed-use: its lower floors operate as rentals, while the upper floors hold 81 condominium residences developed by Toll Brothers City Living, entered through a dedicated Park Avenue South lobby. The ownership homes sit high in the building by design, which gives them light, privacy, and long views over a fast-rising neighborhood.
The architecture is the signature. De Portzamparc shaped the tower as a prism — angled, reflective planes that catch light and give the building a sculptural presence on the Park Avenue South skyline, while producing distinctive angled rooms and multi-exposure layouts inside. It is a genuinely architect-driven building in a corridor that has transformed over the past decade from a wholesale district into one of Manhattan's most dynamic residential and dining neighborhoods.
For buyers, the case is a new-construction condominium — with the financing latitude, ownership flexibility, and resale ease the structure provides — by a marquee architect, lifted above the street on the high floors, with a deep amenity package and a central NoMad address. It offers the convenience of being equidistant from Flatiron, Gramercy, and Murray Hill, with Madison Square Park a short walk west.
Architecture and unit composition
The building's crystalline massing is its defining feature: de Portzamparc's faceted glass planes give the tower a sculptural profile and open angled, multi-exposure layouts within. Because the condominium residences occupy the upper floors, the ownership homes enjoy elevated light and views as a baseline, with the highest floors commanding sweeping looks over NoMad, the Flatiron skyline, and the Midtown towers to the north.
The 81 condominium residences range from one-bedrooms through larger multi-bedroom layouts and penthouses, finished to a contemporary new-construction specification with floor-to-ceiling glass, modern systems, and the high ceilings the design affords. Floor level and exposure are the primary value drivers — the upper-floor and corner homes, with the building's best light and views, carry the premiums, and the angled prism geometry means exposures vary meaningfully line to line.
Building operations
The condominium runs as a full-service, white-glove operation with a 24-hour doorman and concierge and a dedicated Park Avenue South entrance separate from the rental component. The amenity package is extensive: a fitness center with a lap pool and jacuzzi, a yoga room, a spin room, and a steam room; a 27th-floor sky lounge opening to a landscaped terrace; a garden courtyard; a residents' lounge; a screening and media room; a golf simulator; a children's playroom; and a conference room. The building is pet-friendly. As a condominium, purchases clear through a right-of-first-refusal rather than a co-op board process, with the financing flexibility, pied-à-terre and investment ownership latitude, and subletting freedom condominium ownership affords.
The NoMad location is among the most convenient in the central spine of Manhattan. Madison Square Park, the dining and retail of NoMad and Flatiron, and the shops and restaurants of Park Avenue South are at the doorstep, with Gramercy Park to the south and Murray Hill to the east. The 6 train at 28th Street is steps away, with the N/R/W close by and Grand Central a short ride or walk north.

The 421-a benefit has run its term. Taxes on these units have stepped up toward the full assessed amount, so the low carrying cost this building once carried is no longer available. Price from the current tax bill, and treat any comparable sale made while the abatement was still running as a different asset.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00857-7503) 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 from recorded condo declarations and offering plans.
What to know if you’re buying
The condominium structure is a core advantage. There is no co-op board admissions process — purchases clear through a right-of-first-refusal — and financing is flexible, with pied-à-terre, LLC, trust, and investment ownership customary and subletting permitted on condominium terms. For buyers who want a NoMad address with ownership flexibility, that combination is central.
Buy the floor and the view. Because the ownership residences sit high in the tower and the prism geometry varies exposures line to line, floor level and orientation drive both daily light and resale value here — target the higher floors and the corner lines, and confirm the specific exposures of any apartment. The boutique ownership count means inventory is limited; when a well-positioned home comes available, it merits decisive attention. Review the common charges, building financials, and the condominium's relationship to the rental component as part of due diligence.
What to know if you’re selling
Lead with the architecture and the scarcity. A de Portzamparc–designed tower, a crystalline glass facade, and an 81-residence ownership count are durable differentiators in a NoMad market that has grown crowded with newer inventory — and the small resale pool means a well-positioned home faces limited direct competition.
Emphasize the condominium mechanics, the amenity suite, and the high-floor light. A resale clears through a right-of-first-refusal rather than a board interview — a faster, more predictable path that appeals to the financing- and flexibility-minded buyer this building attracts — and the deep amenity package and elevated views are the features that set the building apart from the surrounding stock. Price to the apartment's floor and exposure, benchmark high-floor and corner homes to the building's premium tier, and present the design pedigree, the amenities, and the central NoMad location together.

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.
