Italian brand Molteni&C has outfitted a penthouse in Rafael Viñoly's 432 Park Avenue, adding built-in wooden window seats to frame the views of Central Park.

Molteni&C designer Matteo Nunziati oversaw the transformation of the 8,256-square-foot (767-square-metre) penthouse in the super-skinny Midtown Manhattan tower. The makeover involves simple finishes, built-in furniture and designs from the brand.

The expansive square-shaped windows that give the 96-storey-high 432 Park Avenue its iconic gridded appearance are retrofitted with upholstered benches in the living room, dining area and a bedroom.

This detail helps alleviate the fact the deep glazing takes up a lot of floor space – a feature of the design that Uruguayan architect Rafael Viñoly expressed disappointment about following its completion in 2015.

Encasing these windows is eucalyptus wood, which enhances their distinct square shape and matches the tone of the dark wooden flooring that Nunziati designed for the residence.

White walls, spacious rooms and ample natural light characterise the rest of the interiors. Finishes balance a palette of dark and pale tones, with pops of mint green and rusty red offered by furniture.

A sitting area is anchored by a long, dark Breeze sofa by Nunziati set atop a soft green rug. Two cream-coloured Allure armchairs and a Trevi coffee table, also by Nunziata, encircle a round red ottoman.

Pieces that accent the sitting area in photography include low black tables and large artwork. There is also a D.153.1 armchair and D.552.2 table by Italian designer Gio Ponti, although these are not visible in the imagery.

Adjoining the living room is a dining area with a marble Filigree table. Dark cushioned Chelsea chairs by Rodolfo Dordoni, who is also a designer at Molteni&C, furnish the space.

One of the bedrooms features an upholstered bed frame in cream – forming part of a grey and cream materiality that runs throughout. A sitting nook in front of a window is completed with two seafoam-green chairs, an oval mirror and two round-end tables.

Reaching 1,396 feet (425 metres), 432 Park Avenue is currently the tallest residential building in the world and the second-tallest building in New York, after One World Trade Center in Lower Manhattan.

The grid-like skyscraper is constructed with equal-width vertical and horizontal columns and beams.

Every 12 floors of the structure are left open, acting as a hollow area for the wind to pass through. Supporting the structure is a reinforced concrete core, which houses elevator shafts and mechanical services.

Viñoly's residential tower comprises 104 residential units, with New York firm Deborah Berke Partners as the overall interior designer.

Residents also have access to two gyms, a lap pool, a library, a meeting room, a cinema, a children's area and a wine shop.

Penthouses occupy the 88th to the 95th floors. Each has double entrances, a private elevator, underfloor heating and home automation systems.

In 2014, one of the penthouses sold for 95 million US dollars and is considered as one of the most expensive apartments in the world.

Another high-end unit, located on the 92nd floor, was overhauled by New York designer Kelly Behun with a pale palette to complement the Manhattan views.
