Inside Some of the Most Expensive & Extravagant Homes in the UK

Yup, that's the right price tag. And get this: That's the price for a townhouse in London! OK, so it is one of the original mansions in London's Mayfair neighborhood, but still, it shares walls with other homes. Originally built in 1732, the home underwent a major refurbishment in 1908 that was helmed by famous architect Ralph Knott.

This jaw-dropping home is located right next to London's famed Hyde Park, and despite being right in the middle of the city, the Edwardian Baroque-style mansion boasts truly impressive square footage. It has nearly 15,000 square feet, with 12 bedrooms, a massive central kitchen, a gym, and a two-car garage.

Most of the townhome's 12 bedrooms are quite spacious and minimalistic. Rustic wood beams across the ceilings add lots of character and visual interest, and the views of the city and Hyde Park from the wide windows are quite stunning. We even kind of like the pale wood floors and the juxtaposition between them and the dark wood beams.

One particularly shocking feature of the Mayfair mansion is its indoor swimming pool. It's truly massive! There's also a spa, a gym, a separate spa pool, sauna, a rooftop terrace, and a screening room. The teak deck and high ceilings surrounding the pool cut a particularly impressive image.

Every room in the home is spacious and open. Although the dining room is narrower, it's still huge and actually opens out to yet another outdoor terrace via floor-to-ceiling French doors. The room is absolutely flooded with natural light, and features some really pretty architectural details.

Set a bit outside the hustle and bustle, but still within the city limits, this unusual mansion is over 18,000-square-feet and has 10 bedrooms and 10 bathrooms. It sits on two acres of land and interestingly, features self-contained staff quarters that comprise 4,400 square feet of the home's area.

Unlike the previous home, this one is a new build that's been constructed in a modern style. The home features several curved exterior walls that create a really interesting look, and it has tons of floor-to-ceiling windows that bring the outdoors in. This office, for example, is surrounded by windows.

Is it just us or does this look like something out of The Jetsons? Because of the curved architecture of this home, the balcony has quite a distinctive shape. The home office looks right out over this area, which must be super calming in the middle of a work day. Most impressive is that view, though.

In a word, this home is glitzy. The entire place is decorated in gold tones, glass, and crystals, which creates quite a distinctive and extravagant vibe throughout. Each room is quite spacious and the home benefits from an open floor plan. The formal dining area is accessed from the home's impressive entryway.

One of the most unusual features of this pricey home is its large central elevator, which is constructed almost entirely of glass. The elevator stops at each of the home's three floors. The home also has an indoor swimming pool that opens to the gardens, a home gym, billiards room, tennis court, and a four-car garage.

Although it's much smaller, there's another home in the Mayfair area of London that is also currently listed for sale. At £40,000,000, this one is a six-bedroom, six-bathroom mansion with three receptions areas that comprise about 8,500 square feet. The home is five stories tall and has a beautiful Edwardian-style facade.

This incredible mansion has a grand entryway with a fireplace (one of many) and a double-height ceiling. An L-shaped staircase sits against an ornate wall constructed of the same wood as the stairs, and leads up to the second floor. The dining room, kitchen, and a guest suite can be reached from the entryway.

Although we suppose this room is likely used as a family room or casual entertaining space, it looks a whole lot like something seen in a museum to us. The architecture is quite distinctive and the fireplace that acts as the room's centerpiece is one of the most ornate of several in the home.

Imagine having a reception hall at home. Well, this home's dining room is just that. The elaborate space is set up to celebrate grand occasions like weddings and other major life events. The room is wallpapered and has gleaming limestone flagged flooring that blends seamlessly with the home's entryway, creating quite the reception.

In contrast to the ultra-traditional feel of most of this luxurious home, the indoor/outdoor lounge area is quite modern. The swimming pool is technically indoors, but opens directly to an outdoor lounge space via retractable doors. The tiled courtyard is completed with a sauna, a bar, and large relaxation area.

Situated on about 11 1/2 acres of land, this sprawling mansion is on the outskirts of London. It has eight bedrooms, eight bathrooms, a heated outdoor swimming pool (yes, in London!), its own six-hole golf course, a movie room, and get this — its own mini bowling alley. There's also a separate guest house with three bedrooms.

This mansion looks completely traditional from the outside, but the interiors have all been modernized and the entryway exemplifies that immediately. It features sleek, nearly black hardwood floors, bright white walls, and a breathtaking glass spiral staircase leading to the home's second story.

Of all the home's we looked at, this is the only listing that actually included a photo of the kitchen, and we can totally see why. This home's kitchen is huge, modern, and equipped with top-of-the-line appliances and a massive center island that could easily double as a dining area.

The home's spacious bathrooms continue with the modern, minimalistic black-and-white theme and feature giant soaking tubs, glass and tile showers, marble accents, and sleek art-forward furniture and decor. The master suite has dual en-suite bathrooms that flank either side of the suite.

The mansion's in-home movie theater is one of its smaller spaces, and also one of the coziest. Unlike the rest of the house, it's decorated in deep, rich jewel tones and features heavy drapery framing the big-screen. The walls are covered in velvet and comfy looking velvet couches offer plenty of seating.
