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.”

Direct elevator access on both levels enhances privacy, while south, east and north exposures fill the home with natural light. The great room features dramatic double height ceilings and floor to ceiling windows, opening directly to one of two private terraces for seamless indoor–outdoor living.
