These renderings offer a full look at Álvaro Siza's luxury condominium tower in New York, which marks the Portuguese architect's first project in the US.

Produced by visualisation company The Boundary, the set documents the interior and exterior of the 611 West 56th Street residential tower, which is currently under construction in New York's West Side overlooking the Hudson River.

Pritzker Prize-winner Siza has designed the 37-storey condo building with a stepped form featuring pale Turkish limestone cladding. This facade is punctuated by large windows with thin frames that offer views of the New York surroundings.

"In all the residences, maximising far-reaching views of Midtown, Downtown, and the Hudson River was a top priority," said Siza.

A four-storey crown, also covered in limestone, rises on the top.

The images also preview the tower's 80 boutique residences, designed by Michael Gabellini and Kimberly Sheppard, who run New York firm Gabellini Sheppard Associates.

Among the homes are a mix of one-, two- and three-bedroom units, penthouses and duplex maisonettes with access to private terraces. The decor is minimal, comprising pale stone and marble, bright white walls and wooden flooring.

These pared-back details continue into the building's amenities, which include a fitness centre, a yoga studio, a boxing gym and a children's playroom. Residents will also have access to a large lounge area, dining room and kitchen for entertaining guests.

An outdoor garden on the fourth floor designed by landscape architect M Paul Friedberg, which will include a sculpture designed by Siza, are among other features.

Sumaida + Khurana and LENY, the real estate firms behind the project, released the final details ahead of the sales opening later this month. The cost of a one-bedroom residence is expected to start at $1.26 million (£1.04 million).

The imagery set marks the first full look at the building the 86-year-old architect was enlisted to design in 2015, marking his first commission in the states. Siza told Dezeen that he "didn't expect" to get such a project in an exclusive interview earlier this year.

Siza, who won the Pritzker Prize in 1992, is based in Matosinhos, a small coastal city near Porto, Portugal. He began his architecture career in 1954 and has designed buildings in several European and South American countries, along with Korea and China.

Among his well-known projects is the Expo'98 Portuguese National Pavilion in Lisbon and its scooped concrete roof, which Siza described in an interview with Dezeen as difficult to create.

611 West 56th Street is among a host of residential towers that high-profile architect have designed for the city, including the neighbouring Via 57 tower by Bjarke Ingel's firm BIG.

Renzo Piano, David Chipperfield, Norman Foster, Rafael Viñoly and Thomas Heatherwick are among the others currently contributing to the city's quickly changing skyline.
