The block of East 79th Street between Fifth and Madison is one of the most heavily protected residential blocks in Manhattan. The Metropolitan Museum Historic District covers its western end; four individual landmarks stand along it to the east; and the south side is an unbroken run of Gilded Age mansions. A new fifteen-story residential building on this block should not have been possible. It was possible at number 27 because the district boundary, drawn in 1977, stops before this lot — a fact that should be verified by tax lot rather than assumed from the block, because PLUTO's historic-district field does not carry it and the surrounding parcels all do.
What stood there instead was a small piece of architectural history. In 1969–70 the Austrian architect Hans Hollein remodeled an 1887 brownstone into the Richard Feigen Gallery, replacing the front with a plain stucco field punctuated by a near-neutral grid of windows and marking the entrance with a pair of two-story stainless-steel columns drawn from Adolf Loos. It was among the first works of the historicizing formalism that would define the following two decades, and it was the most conspicuous American building by an architect who would take the Pritzker Prize in 1985. Hanae Mori later took the building as her American flagship. Because it was never designated, it came down in 2016 under a routine full-demolition application. Any honest account of 27E79 has to hold both facts at once: the site's preservation status is exactly what allowed a very good new building, and exactly what allowed the loss of the old one.
The replacement is a slender limestone building on a 24-foot lot, designed for record by H. Thomas O'Hara Architects with the design and interiors by Cabinet Alberto Pinto of Paris, and developed by Adellco. The result is a Beaux-Arts elevation argued in contemporary terms: a glass-domed entrance marquee over a barrel-vaulted vestibule, paired arched windows with Juliet balconies stacked through the upper floors, carved surrounds in the middle of the stack, an arched cornice near the top and a set-back final story behind iron railings. On a block of nineteenth-century masonry, it reads as an infill that has accepted the block's terms rather than as an exception to them.
The program is deliberately small: seven residences over fifteen stories, plus one ground-floor retail unit. That is a maisonette with a garden at the base, single-floor apartments on the fifth and sixth floors, three duplexes above, and a triplex penthouse at the top — no repeating line, no floor plate used twice above the sixth. Buyers should understand the consequence. There is no "typical unit" at 27E79 and no internal comparable set; every apartment is its own product, and pricing has to be built from the specific home.
Architecture and unit composition
The lot is 24 feet wide and roughly 102 feet deep, with a building footprint about 22 by 72 feet. Everything about the building follows from that: a single residence per floor through the lower stack, duplex and triplex configurations above to produce livable square footage, and a façade whose entire architectural argument is made in vertical composition because there is no width to work with.
The limestone elevation is organized in horizontal registers. A bandcourse sits above the first floor, with hanging lanterns draped over it and an oculus above the retail entrance; the second and third floors are set in dark metal surrounds; a bracketed bandcourse crosses above the third floor; the fifth through eighth floors carry carved window surrounds; a further bandcourse runs above the eighth; the ninth through twelfth floors return to paired arched openings in dark metal with Juliet balconies; a large arched window marks the thirteenth; and the top story sets back behind iron railings above an arched cornice. Three topiary planters stand at the sidewalk. The curved geometry of the entrance dome is repeated deliberately in the arched openings above it.
The residences are finished to a Parisian specification rather than a New York new-development one: fireplaces, La Cornue ranges, Miele and Sub-Zero appliances, and bathroom vanities in parchment, lacquer and Movingui wood. The maisonette carries a large private garden. The fifth-floor residence is documented at roughly 1,475 square feet with a long entrance gallery leading past an enclosed kitchen to a combined living and dining room — a plan closer to a prewar apartment than to an open-plan condominium, and consistent with the building's overall argument.
Building operations
27E79 is staffed as a full-service building at very small scale: full-time doorman and concierge coverage, a fitness center, a bicycle room, private storage, and keyed elevator access opening directly into the residences. Seven households carry that staffing, and common charges per square foot should be read against the staffing model rather than against buildings four times the size.
Three diligence points follow from the scale. First, the reserve and the operating budget matter disproportionately — a single mechanical or envelope item is spread across seven apartments. Second, the ground-floor commercial unit is separately owned and its use, its common-charge allocation and any restrictions in the declaration should be reviewed. Third, DOB NOW records show substantial interior renovation filings in 2026 covering the triplex penthouse and one of the duplexes; construction activity in a seven-unit building is not a background condition, and its scope and schedule are worth confirming with the managing agent before contract.
Policy framework
Ownership form: Condominium. Transfers close through a board right of first refusal rather than a cooperative approval, typically in 30 to 45 days.
Pied-à-terre, subletting, LLC, trust and foreign ownership: Permitted under the standard condominium framework. Minimum lease terms and any leasing restrictions in the house rules should be confirmed with the managing agent.
Pets and house rules: Not documented in public records. Request the house rules together with the current budget.
Real estate taxes: No abatement or exemption appears on the lot. Residences have carried full unabated taxes since the first closings, which is unusual among 2020-delivery Manhattan condominiums and materially changes the monthly number relative to abated inventory.
Flip tax: Not documented in public records. Confirm any resale capital contribution with the managing agent before pricing a sale.

27E79 sells into the boutique ultra-luxury Upper East Side condominium market — the small set of new buildings within a few blocks of Central Park that offer deeded tenure, condominium rules and contemporary systems in a neighborhood otherwise defined by prewar cooperatives. Its buyer is frequently a purchaser the surrounding co-ops would not take: an entity, a trust, a part-time resident, or a foreign buyer.
Three factors govern how the record should be read. The sellout ran from late 2020 into the middle of the decade at a deliberate pace, which is normal for a seven-unit building and should not be read as weak absorption. The absence of any tax abatement puts the carrying number above comparable abated new construction and should be modelled from the current bill rather than a projection. And because no two apartments in the building share a plate above the sixth floor, there is effectively no same-building comparable — pricing has to be built from the specific unit's configuration, outdoor space and exposure, and from the wider set of boutique Upper East Side condominiums.

What to know if you’re buying
Verify the landmark status by lot, not by block. The building is not designated and no Certificate of Appropriateness is required, but every parcel to the west is inside the Metropolitan Museum Historic District. The distinction governs what can be altered and what could be built nearby.
Understand the lot width. At 24 feet, the building has no width to spare. Test light and exposure in the specific unit, and understand which windows face lot lines and what protections, if any, exist.
Underwrite full taxes from the first month. There is no 421-a, 485-x or J-51 benefit here. For buyers comparing against abated new construction, this is the single largest gap between the headline price and the true monthly cost.
There is no internal comparable. Maisonette, simplexes, duplexes and a triplex penthouse — seven homes, seven configurations. Any per-foot analysis has to be unit-specific.
Review the commercial unit. The ground-floor retail unit is separately owned. Read the declaration on permitted use, common-charge allocation, and any restrictions.
Ask about current construction. Recent filings cover major interior work in two of the seven residences. In a building this size, that affects elevator access, noise and building services.
What to know if you’re selling
The address and the block do most of the work. East 79th between Fifth and Madison, opposite the mansion row and a short walk from Central Park and the Metropolitan Museum, is among the most defensible locations in Manhattan, and new construction on it is close to unrepeatable.
Sell condominium tenure on a cooperative street. The buyer pool that cannot transact in the surrounding prewar co-ops is a large part of this building's demand. Position for it directly.
Present the design attribution. A Paris-designed interior specification and a limestone Beaux-Arts elevation separate this building from the glass-and-metal alternatives; it is a legitimate and documentable point of difference.
Be direct about taxes and about the thin comparable set. Sophisticated buyers will find both. Presenting the unabated number with a True Monthly Carrying Cost analysis, and framing pricing from configuration rather than from a building average, produces better outcomes than letting either surface in diligence.

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.
