611 West 56th Street, PH-1

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 Square, Columbus Circle, Waterline Square, and Billionaires’ Row, this is the most refined addition to the West Side’s emerging “architects’ row.”

The Sky Residence Penthouse on floor 30 of SIVA Tower is a full floor, triple corner four bedroom, four and a half bath home spanning 3,357 square feet with breathtaking views. As part of The Sky Collection, every bathroom is ensuite and sits on a window wall, creating rare, light filled spaces with exceptional privacy and impact. Two private elevators open into an oak wrapped landing and gallery with a cove lit floating ceiling, leading to a dedicated refuse room with recycling and a separate laundry room with a washer, dryer, and utility sink.

Five inch oak flooring and oversized perimeter windows fill the residence with natural light and frame dramatic views throughout the day. At the center, a 572 square foot great room offers defined living, dining, and entertaining areas, complemented by an OEA faucet package, Simonswerk concealed hinges, a Comelit entry system, and central HVAC with linear diffusers and recessed shade pockets. A well placed powder room sits off the foyer, providing convenient guest access while preserving the privacy of the bedroom wing.

The windowed, eat-in Italian Aster Cucine kitchen and island, pairing warm walnut cabinetry with edge lighting and honed Grigio Nicola marble on the countertops and backsplash. A full suite of Gaggenau appliances includes a 48-inch panel-ready refrigerator, freezer, dishwasher, five-burner gas range, two cabinet ovens, a speed oven, warming drawer, and an 80-bottle wine and beverage cooler. Additional professional-grade details include a Bosch pullout hood, Julien stainless steel sink, integrated recycling bins and a double full height pantry.

All four bedrooms include ensuite, windowed bathrooms that bring in natural light and maintain a consistent, elevated design language. The double corner primary suite functions as a private retreat, anchored by a five fixture spa bathroom with an Aster Cucine floating double vanity, dual medicine cabinets, heated floors, a Kartell Laufen wall hung toilet, a freestanding soaking tub, and an oversized rain shower. The three secondary bathrooms are also windowed, offering Aster Cucine vanities, medicine cabinets, deep soaking tubs with glass guards, walk in showers, and NK toilets.

A landscaped garden by M. Paul Friedberg, featuring original works by Álvaro Siza, anchors the building’s serene outdoor environment.
