SIVA Tower, designed by Pritzker Prize–winning architect Álvaro Siza with interiors by Gabellini Sheppard, is a rare architectural landmark on Manhattan’s West Side. Clad in Perla Bianca limestone and rising as a slender sculptural form, the tower offers only 77 residences, each conceived with Siza’s signature precision, calm, and timeless restraint.

Positioned within Hudson West, just north of Hudson Yards and moments from Lincoln Center, Columbus Circle, Waterline Square, and Billionaires’ Row, this is the most refined addition to the West Side’s emerging “architects’ row.”

Residence 3A is an 868 square foot corner one bedroom, one and a half bath home, distinguished by its rare A line layout, exceptional flow, and abundant natural southeast light. Oversized windows wrap both the living and bedroom spaces, while integrated pockets for shades and curtains preserve clean architectural lines. Wide plank white oak flooring, concealed Simonswerk hinges, a Comelit entry panel, and discreet HVAC diffusers elevate the home’s serene contemporary aesthetic.

The open Italian kitchen by Aster Cucine pairs warm walnut cabinetry with honed Grigio Nicola marble and a well proportioned island. A full suite of Gaggenau appliances includes a panel ready refrigerator, freezer, and dishwasher; a four burner gas range; built in oven and microwave; a Bosch pull out hood; and a Julien stainless steel sink with OEA fixtures.

The primary suite offers a tranquil retreat with a dedicated dressing area and a beautifully appointed three fixture bath featuring a floating Aster Cucine vanity in Tundra Gray marble, a deep soaking tub with glass splashguard, radiant heated floors, and an NK toilet. A perfectly positioned powder room includes a Kartell Laufen wall mounted toilet, floating vanity, and oversized mirror. Two generous entry closets and an in unit Bosch washer and dryer complete the home.

611 West 56th Street delivers a comprehensive amenity experience, including a Technogym Fitness Room with equipment by Antonio Citterio, dedicated Yoga and Boxing Rooms, men’s and women’s changing rooms with showers and illuminated steam rooms, a Children’s Playroom, a Media Room with billiards, and an elegantly furnished Residents’ Lounge by DDC and Minotti with a catering kitchen. A landscaped garden by M. Paul Friedberg, featuring original works by Álvaro Siza, anchors the building’s serene outdoor environment.

A 24 hour attended lobby, concierge, porters, management, cold storage, bike room, and supplemental laundry room ensure effortless living. Private storage and parking with direct lobby access are available for purchase.

The neighborhood offers immediate access to Hudson River Park, Riverside Park South, Pier 97, Pier 96 Boathouse, Pier 94 Sunset Studio, De Witt Clinton Park, and convenient transportation via the N, R, W, and 1 trains and multiple 57th Street bus routes.
