A Private Pricing Opinion — what your apartment at Chelsea Green 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.
Chelsea Green is the sustainability-forward face of Chelsea's condominium era. Completed in 2012 by Alfa Development to a design by the Stephen B. Jacobs Group, the fourteen-story building was built to LEED Gold standards — a credential that was still genuinely differentiating at its debut and that shows up in the things owners feel daily: high-performance windows, efficient mechanicals, healthier indoor air, and lower energy carry. It occupies one of Chelsea's most central blocks, West 21st between Sixth and Seventh, the same stretch that anchors the neighborhood's mid-rise condominium stock, a short walk from both the F/M and the 1.
For buyers, the building pairs that green envelope with a full amenity program and condominium ownership — flexible financing, no co-op admissions board — a combination that has kept it among the more sought boutique condominiums in central Chelsea.
Architecture and unit composition
The building reads as crisp and contemporary, its design driven as much by performance as by form: floor-to-ceiling high-U-value windows that bring in light while holding heat and blocking street noise. The 51 residences run from one to three bedrooms, finished to a high specification — FSC-certified walnut floors, modern kitchens and baths, and the open layouts the period's buyers expect. The upper-floor and outdoor-space homes carry the building's premiums; the green-building credentials add a layer of appeal that the surrounding pre-war stock structurally cannot offer.
Building operations
Chelsea Green runs as a full-service condominium with a 24-hour doorman and concierge and a live-in superintendent. The amenity set is among the deeper ones for a building of its size: a landscaped rooftop deck with skyline views, a fitness room, a spa with a sauna, a billiard room, a bike room, and private storage. Washer/dryers are permitted in residence and the building is pet-friendly. As a condominium, financing is flexible and purchases clear through a right-of-first-refusal rather than a co-op board package and interview.

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.

Full closing history with price-per-square-foot over time, the complete retrade record, and every line that has traded.
Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00797-7508) 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
As a condominium, the purchase path is the lighter one — a right-of-first-refusal in place of a co-op board, flexible financing, and the customary openness to pied-à-terre, trust, LLC, and investment ownership. Subletting is freer than at a Chelsea co-op. Value here is driven by the home — exposure, floor, outdoor space — layered on the building-level draws of the amenity program and the green-building efficiency that lowers operating cost over time. We help buyers read the offering plan and financials, weigh common charges and taxes, and benchmark a given line against Chelsea's boutique-condominium set.
What to know if you’re selling
The selling case is distinctive: a LEED Gold, full-service condominium with one of the deeper amenity packages in central Chelsea. Sustainability credentials and a real spa-and-fitness program differentiate a listing from the neighborhood's older and thinner-amenity stock, and they appeal to a buyer pool that increasingly prices efficiency and wellness into the decision. Closing mechanics are condominium-standard — a right-of-first-refusal and a faster, more predictable timeline than a co-op process. With turnover light, a well-positioned home benefits from scarcity within the building; pricing belongs against the boutique full-service condominium set.

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.
