55 West 17th Street is a 2017 condominium that did something difficult: it dropped a brand-new, 19-story tower onto a Ladies' Mile block and made it feel like it belonged. Designed by Morris Adjmi — an architect known for new buildings that converse with their historic surroundings rather than ignore them — and developed by Toll Brothers City Living, the building is clad in handmade Danish white brick with bronze entrance detailing, window frames, and cornice work, and stepped with setbacks on the upper floors that echo the rhythm of the masonry stock around it.
For buyers, the value is the rare pairing of new-construction systems and amenities with a design that respects its block, in one of downtown's most central and walkable locations. Standing between Fifth and Sixth Avenues at 17th Street, the building sits at the crossroads of Flatiron, Chelsea, and Union Square — minutes from the Union Square subway hub, the Greenmarket, and the dense retail and dining of all three neighborhoods.
Architecture and unit composition
The façade is the building's signature — handmade Danish white brick, an unusual and labor-intensive material choice, set off by bronze architectural metal at the entrance, windows, and cornice. Setbacks on the upper floors create visual articulation and give the higher residences private outdoor space and open views. The design deliberately borrows the proportions and texture of the surrounding Ladies' Mile architecture while remaining unmistakably contemporary.
The 53 residences carry the finish program of a quality new-development project: wide-plank oak floors, kitchens with custom cabinetry, marble countertops and backsplashes, and Gaggenau appliances. Layouts span one- through three- and four-bedroom homes, with the upper-floor and setback units commanding the premium for light, views, and terraces. As new construction, the building delivers contemporary ceiling heights, modern mechanical and air systems, and a full private amenity suite — infrastructure built in from the ground up.
Building operations
55 West 17th runs as a full-service condominium with a live-in resident manager. The amenity package is deep for a boutique building: a fitness center, a children's playroom, a residents' lounge with a billiards table and catering kitchen, a screening room with a wet bar, a landscaped terrace with a grilling area, and bicycle storage. As a condominium, ownership is flexible — financing rules are condominium-standard, pied-à-terre and investment purchases are customary, and resale clears through a right-of-first-refusal rather than a co-op board admissions process. The building is pet-friendly.

Facade safety — Local Law 11

What to know if you’re buying
This is new-construction living in a design-conscious building at a prime downtown crossroads. Ownership is flexible — condominium financing rules apply, pied-à-terre and investor purchases are customary, and there is no co-op board package or interview, only a right-of-first-refusal. The amenity package is unusually deep for the building size, and the new-development systems mean turnkey, low-friction living. Evaluate each home on floor, light, and outdoor space — the setback units carry private terraces and the strongest views. We help buyers read the offering plan, the common-charge structure, and the comparison set across the Flatiron and West Chelsea condominium market.
What to know if you’re selling
Lead with the design and the amenities. A Morris Adjmi façade in handmade Danish white brick, a full amenity suite, and new-construction systems are durable differentiators in a neighborhood otherwise dominated by older loft and co-op stock. Benchmark to the recent-vintage Flatiron and West Chelsea condominium set, and showcase the finish quality, light, and any terrace. The condominium structure is itself a selling point — a faster, more predictable closing and a wider buyer pool, including pied-à-terre and investment purchasers. The best results come from presentation that lets the building's design and amenities speak.
