120 West 72nd Street — the Harsen House — is a 2007 condominium designed by BKSK Architects, mid-block on one of the Upper West Side's principal cross streets between Columbus and Amsterdam Avenues. Its distinction is twofold: it is a genuinely boutique full-service building, with seventeen residences behind a 24-hour-doorman lobby, and it was one of the first residential projects in New York City to build to LEED standards, earning Silver certification at a time when green residential construction was still rare. The name nods to the Harsen family, early landholders whose farmhouse once stood in this part of the West Side.
BKSK's design is contextual rather than flashy — a masonry building that respects the scale and materials of its surroundings while delivering the light, systems, and layouts of new construction, with interiors by Andres Escobar. For buyers, the combination is the appeal: a small, serviced condominium on a prime 72nd Street block, walkable to Central Park, Riverside Park, Lincoln Center, and the transit hub at 72nd Street and Broadway, with the operational reassurance of a doorman building and the efficiency of a LEED-designed envelope.
This is a boutique building whose value lives at the apartment level. With seventeen residences, floor, exposure, and layout — not any building-wide average — drive pricing.
Architecture and unit composition
BKSK's Harsen House is a work of contextual contemporary design: a masonry facade with setback massing that sits comfortably among its Upper West Side neighbors, paired with the daylight and floor plans of a new building. The LEED Silver program shaped the building's systems and envelope, an early example of sustainable design in a Manhattan condominium. Andres Escobar's interior work carries the design intent into the residences and common spaces.
At ten stories and seventeen units, the building keeps a boutique profile with a real service package — a 24-hour doorman, a fitness center, storage, and a bicycle room. Residences run through family-sized layouts, with the higher and better-exposed homes commanding the building's premiums.
Building operations
120 West 72nd Street operates as a boutique full-service condominium: a 24-hour doorman, an elevator, a fitness center, private storage, and a bicycle room, within an early LEED-certified building. Common charges reflect a small building carrying full-time staffing and an amenity set; the LEED-designed systems can support operating efficiency, but buyers should model the full monthly carry and review reserves and any capital history during due diligence, as is prudent for any condominium approaching two decades of occupancy. In a seventeen-unit building, ownership tends toward long-term, primary-residence owners.

As a condominium, 120 West 72nd Street prices on a price-per-square-foot basis, with the higher floors and best-exposed residences carrying the building's premiums. Turnover is light in a seventeen-unit building; both resale and owner-rental activity occur, but this is an ownership condominium, not a rental building. Apartment-level context — floor, exposure, layout, outdoor space where present, and condition — drives pricing far more than any building average, and the doorman service, the BKSK design, and the LEED pedigree support pricing for well-presented residences.

What to know if you’re buying
It's a boutique doorman building. A 24-hour doorman and a fitness center back a seventeen-unit building — full service at boutique scale. Price that combination accordingly.
The green design is real. As an early LEED Silver residential project, the building was designed for efficient systems; confirm current operating performance and any capital plans during due diligence.
Condo flexibility is real. Pied-à-terre, subletting, foreign buyers, and LLC/trust ownership are permitted under the declaration; closings run on condo timelines.
Underwrite a mature new-construction building. Now more than fifteen years old, the building should be reviewed for reserves and any capital history, as with any condominium of its age.
Mansion tax thresholds apply. At this building's pricing, the $1M, $2M, and higher cliffs can be in play. Run pricing through the Mansion Tax Calculator.
What to know if you’re selling
Lead with the design and the pedigree. The BKSK architecture, the Escobar interiors, and the early LEED certification are differentiators; foreground them.
Pricing requires apartment-level comps. With seventeen residences, floor, exposure, and layout move the number more than any neighborhood average.
Own the location. The 72nd Street address — between Central Park and Riverside Park, near Lincoln Center and the transit hub — is a genuine selling point.
