There are penthouses with great views — and then there’s PH6/7 at 611 West 56th Street, a 5,100-square-foot duplex perched high above Manhattan with its own 1,572-square-foot wraparound terrace.
Listed for $15 million, the oversized two-level residence sits in a Pritzker Prize–winner–designed tower and delivers a true bird’s-eye look at the Hudson River, Midtown, and the far west skyline.
Spread across two full floors and accessed by a private elevator, the residence is one of the marquee offerings inside the first U.S. building ever designed by acclaimed Portuguese architect Álvaro Siza.
Interiors are by Gabellini Sheppard, and the home mirrors their signature aesthetic — clean, sculptural, minimal, and quietly luxurious.
Set on a coveted stretch of Manhattan

Listed by Gilad Azaria and Lolita Peradze at Douglas Elliman, the five-bedroom, five-and-a-half-bath penthouse sits right where Midtown West meets the Upper West Side, in a pocket of the city now nicknamed Hudson West for its proximity to both Central Park and Riverside Park South.

A duplex built around skyline views

The penthouse was designed to frame the city from every angle, with oversized windows and 12-foot ceilings that pull in light from sunrise to sunset. Every bedroom and bathroom has a view — an uncommon flex even by Manhattan penthouse standards.
The two-level layout also gives the residence the feel of a standalone home in the sky, with abundant wall space, long sight lines, and seamless flow between social and private spaces.
A 1,572-square-foot terrace that wraps the entire residence

The wraparound terrace is the showpiece here, stretching along the perimeter of both floors and opening onto nearly 360-degree views.
From the Hudson River’s shimmering edge to the skyscrapers lining Midtown and the far West Side, it’s an outdoor space built for serious hosting, large-scale lounging, and all-day open-air living above the city.
Private elevator access, refined interiors

PH6/7 has its own dedicated elevator landing, giving the duplex direct entry and a sense of separation from the rest of the building.
Their interiors are understated but refined, emphasizing proportion, flow, and natural light instead of ornamentation.
Known for their elevated simplicity, Gabellini Sheppard infused the home with a neutral palette, sculptural details, and wide-plank oak floors that warm up the modern design.
A chef’s kitchen with Italian walnut cabinetry

The kitchen leans fully into high-end luxury, anchored by custom Italian walnut cabinetry, honed Grigio Nicola marble countertops, and a striking waterfall-edge island.
The appliance suite is all Gaggenau, including a refrigerator, freezer, gas cooktop, wine fridge, dishwasher, and speed oven. It’s a true entertainer’s kitchen, designed to look clean and sculptural even when not in use.
The primary suite doubles as a full retreat

The primary suite spans its own spacious footprint and comes with a five-fixture bath wrapped in honed Tundra Gray marble. Heated radiant floors and bespoke lighting elevate the spa-like feel, turning the space into a quiet sanctuary high above the city.
Álvaro Siza’s first U.S. building

611 West 56th Street marks acclaimed architect Álvaro Siza’s American debut.
The 77-residence tower is wrapped entirely in Perla Bianca limestone, with sharp edges and clean proportions that nod to his architectural trademarks. The building joins a stretch of Manhattan increasingly dubbed “architect’s row,” lined with designs by some of the biggest names in the field.
A full suite of boutique amenities

Residents have access to a lengthy list of amenities, including:
- Outdoor garden mezzanine
- Fitness center with yoga and training studio
- Steam rooms and changing rooms
- Media room with billiards
- Children’s playroom
- Large entertaining lounge with separate dining room and full kitchen
- Discreet catering kitchen
- Optional parking and storage
The overall vibe is boutique luxury rather than megatower, with amenities scaled to feel private and intimate.
Located in the emerging ‘Hudson West’ pocket

The building sits where Midtown West meets the Upper West Side, close to both Central Park and Riverside Park South. The area has become a hotspot for architect-driven residential buildings in recent years, and 611 West 56th Street stands among the most refined entries to date.
