The Slate is a boutique Chelsea condominium doing something specific: delivering full-service amenity infrastructure — a staffed lobby, a garage, a fitness center, and a roof deck — at a 29-unit scale that most amenity condominiums cannot match. In a neighborhood whose ownership stock runs from prewar co-ops and loft conversions to large new-development towers, a twelve-story building with roughly two to three homes per floor and a 24-hour doorman occupies a scarce middle: institutional service without institutional density.
The building is ground-up 2006 construction by Karl Fischer, the architect behind a run of early-2000s Manhattan and Brooklyn condominiums, on a mid-block Chelsea parcel between Sixth and Seventh Avenues. That location is the thesis for most buyers here — a short walk to the Sixth Avenue retail spine, to the Flatiron and Union Square districts to the east, and to the gallery blocks and the High Line to the west, on a residential side street rather than a commercial corridor.
For buyers, The Slate reads as a full-service Chelsea condo without the scale, service-charge base, or anonymity of a large tower — a boutique format for buyers who want a doorman and a garage but not five hundred neighbors.
Architecture and unit composition
The building rises twelve stories in contemporary glass-and-masonry, new construction rather than the loft-conversion stock common to the surrounding blocks. The 29 residences are laid out at roughly two to three homes per floor, a boutique density that keeps the building's per-floor privacy high relative to its amenity package. Layouts run to the one- and two-bedroom range typical of 2000s Chelsea new-development, with the finish and light profile of ground-up construction: full-size windows, open kitchens, and in-unit laundry per listing records. The common roof deck and landscaped garden give the building shared outdoor space beyond the private terraces at select units.
Building operations
The Slate operates as a full-service condominium at boutique scale: a 24-hour doorman and concierge, a live-in superintendent, an on-site parking garage, a fitness center, private storage, and central laundry, with the common-charge budget spread across 29 owners. That is an unusually complete service stack for a building this size — buyers should price it consciously against both larger towers (more amenity, higher density, larger fee base) and smaller boutique buildings (lower carry, fewer services). The offering plan and by-laws should be reviewed during diligence; we obtain current building documents from the managing agent for clients at offer stage.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00794-7502) 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
Full service at boutique scale is the product. A 24-hour doorman, a garage, a gym, and a roof deck across only 29 units is a specific and scarce format. Price the service stack against both larger towers and smaller boutique buildings — run the True Monthly Carrying Cost Calculator against your alternatives.
The location is the durable asset. Mid-block between Sixth and Seventh on a residential Chelsea street, walkable to the Flatiron and Union Square districts, the gallery blocks, and the High Line. Walk the block at the hours you'll actually use it.
Verify the policy stack. Pet, sublet, and financing specifics beyond standard condominium conventions are thinly documented publicly. We verify against the offering plan and managing agent during diligence.
Mansion tax applies at two-bedroom pricing. Larger units here cross the $1 million threshold and can approach the $2 million tier — run the Mansion Tax Calculator at the intended price before offering.
What to know if you’re selling
Market the service-to-scale ratio. The pitch is full-service living without tower density — a doorman and a garage in a 29-unit building. Position honestly against the larger condos' deeper amenity stacks and let the boutique format argument carry.
Use same-building and adjacent full-service comps. With 29 units, your building's own history is meaningful but thin in any given window; the full-service condo stock on the surrounding Chelsea blocks rounds out the comp set.
Condition and light drive the premium. In ground-up 2006 stock, updated kitchens and baths and strong exposure separate pricing — stage to the format's strengths.
