A £55 million London mansion was the most viewed property on Rightmove in 2016 — here’s what it’s like inside

The UK’s largest property website, Rightmove on Tuesday released their 10 most viewed properties of 2016.

At the top of the list was a Grade II-listed townhouse in Belgravia, fending off competition from a private island fortress and Harry Potter’s house.

London’s most expensive home features a roof terrace, winter garden, and swimming pool in the basement.

The 10,516-square-foot home is spread over four floors, with a convenient passenger lift for easy access among the house’s seven bedrooms, six bathrooms, and three reception rooms.

Take a look inside the multimillion-pound property below:

Welcome to Eaton Square, a row of townhouses in Belgravia, one of the most prestigious areas of London. The Grade II-listed property is also close to the neighbourhoods of Knightsbridge, Sloane Square, and Chelsea.

The living room oozes opulence, with a gold chandelier, plush furniture, and ornate ceiling decorations. Natural light pours through the large windows and door, which leads to a plant-lined balcony.

The kitchen and breakfast room have a modern, clean feel with marble countertops and sleek appliances, while the silver chandelier adds a touch of glamour.

The dining room is a more austere space, decorated in dark, dramatic colours. With a beautifully designed ceiling above a large table, the room is the perfect setting for an animated dinner party.

Arguably the most impressive part of the house is the basement, where a gorgeous swimming pool runs the length of the room.

One of the house's seven bedrooms — this grand room features a walk-in dressing room, as well as plenty of storage space.

And this bathroom — one of six in total — has a free-standing bathtub with a view out of the window, and two sinks, as well as marble-covered floors, walls, and counters.

There's also an indoor "winter garden," which is dotted with plants that give it an airy feel, while natural light fills the space from the glass-top retractable roof.
