611 W 56th Street #4E

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 4E is an expansive indoor and outdoor two bedroom, two and a half bath home offering 1,131 SF of interior living and an extraordinary 1,080 SF of private outdoor space—2,211 SF in total. When the outdoor area is valued at 50% of interior space, the residence achieves an exceptional adjusted price of $1,111 per square foot, making it a standout long term value.

Oversized windows wrap the living room and hallway, filling the home with natural light. Wide plank white oak flooring, a soft neutral palette, and pockets for shades and curtains create a refined contemporary backdrop. Additional details include an OEA faucet package, Simonswerk concealed hinges, Comelit entry system, and central HVAC with discreet diffusers.

The open Italian kitchen by Aster Cucine features walnut casework and honed Grigio Nicola marble. A full suite of Gaggenau appliances includes a panel ready integrated refrigerator, freezer, and dishwasher; 5 burner gas range with cabinet oven and speed oven; Bosch pullout hood; Julien stainless steel sink; and a Thermador 40 bottle wine and beverage cooler.

The serene primary suite features a floor to ceiling window and a windowed four fixture bath with a floating Aster Cucine double vanity in white marble, two medicine cabinets, deep soaking tub with glass splashguard, Kartell Laufen wall hung toilet, and heated floors.

The second bedroom offers its own ensuite three texture marble bath with walk in shower, floating vanity, Aster Cucine casework, and NK toilet.

A well placed powder room with Kartell Laufen wall mounted toilet and marble topped vanity anchors the entry, along with two coat closets. An in unit Bosch washer and dryer add everyday convenience.

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.
