Huge windows. The grays and whites actually feel cozy with that view.

And then—bam, chandelier city. Ceiling height doing the heavy lifting.

That deck against the trees is nice. Indoor-outdoor thing actually works.

Glass walls everywhere, with skyline peeking over the green. Morning coffee spot.

Dark wood deck, big gray sofas, city backdrop. Yeah, I’d sit here.

The island is massive. Black marble everywhere. Looks a restaurant prep station.

If I had this view, I might actually use the treadmill.

Herringbone floors steal it. Bedroom and lounge blur together behind glass.

Entry gives Art Deco, black-and-white marble doing the most.

Shiny glass towers, lots of steel. Looks a brand-new district.

Details
This penthouse is basically an oversized house stacked onto the top two floors of One Hyde Park, looking straight over Hyde Park and into Knightsbridge. Inside, it feels more like a very large home than an apartment, with big open rooms and long views from one side to the other. The main reception room is the showpiece: it has an eight-meter (about 26-foot) ceiling, a full glass fireplace, and wall-to-wall windows facing the park, so it’s set up for serious entertaining or large gatherings. Off to the side, the kitchen leans into a Japanese-inspired look, with black forest granite on the counters and floors, Gaggenau appliances, and an adjoining breakfast room that uses shoji-style screens instead of blinds, set into grooves cut into the stone.
All five bedrooms have their own bathrooms and built-in wardrobes, and each bathroom has its own marble design. The primary suite is unusually large at around 2,300 square feet, with direct Hyde Park views, two full bathrooms with Jacuzzi-style jet tubs, and big dressing rooms that function more like private wardrobes than simple closets. Away from the bedrooms, there are spaces meant just for downtime and guests: a cocktail bar, a pool table area, and a proper home cinema, plus two separate studies and meeting areas if you want work and calls out of the main living zones.
A big part of the layout is dedicated to wellness and support. There’s a private spa inside the apartment with a treatment room, sauna, and steam room, plus a dedicated gym fitted with Technogym equipment, so you don’t have to rely on the building’s shared facilities if you don’t want to. The back-of-house side is set up for staff, with a separate staff suite, two secondary entrances, and circulation routes that keep service tucked out of sight from the main rooms. In the basement, you get four secure underground parking spaces and four private storage units, which matters in this part of London where space is tight. The whole thing sits within One Hyde Park, which is known for strict security, high privacy, and direct access to Mandarin Oriental-style services, so day-to-day living is designed to be very controlled, comfortable, and low effort for whoever owns it.
