SIVA Tower, designed by Pritzker Prizewinning architect lvaro Siza with interiors by Gabellini Sheppard, is a rare architectural landmark on Manhattans West Side. Clad in Perla Bianca limestone and rising as a slender sculptural form, the tower offers only 77 residences, each conceived with Sizas 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 Sides emerging architects row.

Residence 11 is a full-floor, four bedroom, four and a half bath triple-corner home spanning 3,357 square feet, offering extraordinary scale, privacy, and light. Arrival is an experience with two private elevators open into an exclusive landing and gallery wrapped in rift-cut oak paneling and softly illuminated by a cove-lit floating oak ceiling which also incluses a dedicated refuse room with recycling and a separate laundry room with a washer, dryer, and utility sink.

The residence features 5-inch oak flooring and oversized windows wrap the perimeter, bathing the interiors in natural light and capturing dramatic vistas throughout the day. At the heart of the home, a 572-square-foot great room offers distinct zones for living, dining, and entertaining, elevated by refined details including an OEA faucet package, Simonswerk concealed hinges, a Comelit entry system, and central HVAC with discreet linear diffusers and recessed shade pockets. A perfectly positioned powder room sits just off the foyer, providing seamless access for guests while preserving privacy for the bedroom wing.
