álvaro siza's new york tower tops out at 611 west 56th street

‘611 west 56th street’, the first project in the united states by portuguese architect álvaro siza, has officially topped out in new york. the milestone coincides with the project’s first photography, with the building documented in its current state by joão morgado. previously featured on designboom here, the limestone-clad condominium tower will contain 80 residences across its 37 stories. contrasting the city’s glass skyscrapers, siza’s monolithic scheme culminates in a four-story crown conceived as a ‘stone monument’.

the project’s interiors have been designed by gabellini sheppard associates, the interior architecture and design studio behind tadao ando’s 152 elizabeth. the warm yet pared-down interiors respond to siza’s architecture with a mix of modern materials and custom finishes. meanwhile, on site amenities include: a landscaped garden designed by m. paul friedberg with a sculpture designed by alvaro siza; a fitness room; yoga and boxing rooms; a children’s playroom; a media room with billiards table; and private living and dining rooms for residents.
