They say 'beauty is in the eye of the beholder' and that sentiment rings true when it comes to these unique homes. From controversial tiny homes to mish-mash mansions, they're definitely different.

We have gathered some of the most questionable properties in America, from the tacky to the downright weird and will leave it for you to judge: are these properties crazy cool or truly tasteless? Click or scroll on and decide for yourself...

Should you head to the town of Bremen, Alabama, you'll find a waterside home that's almost too bonkers to be true. Sitting on the edge of scenic Lewis Smith Lake, this modern castle was built in the 1980s and comes with 18 acres of land.

Yet its idyllic setting and abundance of space are somewhat overshadowed by its eye-catching exterior aesthetic...

Known as Smith Lake Castle, the property spans 5,500 square feet spread over four peculiar floors, with sloping walls, asymmetrical ceilings, custom tile work and obscure built-ins that make it truly one-of-a-kind.

The house hit the market in January 2019 with a whopping $5.2 million (£4.1m) asking price, but for some reason the property failed to sell...

Over in Alaska, you'll find a home that isn't hard to spot. This towering, cartoonish-looking house appears to have been plucked from the pages of a Dr Seuss book. Soaring up 185 feet, the property wasn’t built in homage to any of the books' wacky illustrations.

In fact, the former owner, Phillip Weidner, just wanted to increase the height of his log cabin to see nearby Denali Mountain.

Weidner is said to have continued to add layers to the home when he still couldn’t get a clear view through the trees, which is how the house reached such impressive heights.

Weidner died over 15 years ago and the house remains unfinished to this day. It was taken on by another buyer, who intends to continue work on the house. Until then, the gravity-defying home remains a local landmark.

In 2021, this eye-catching hilltop home in Arizona landed on the real estate market for $1.3 million (£1m), offering one lucky buyer the chance to get their hands on a one-of-a-kind piece of real estate.

The 5,913-square-foot house was built in 1980 and can be found in Phoenix. It offers 360-degree views of the desert shrublands from numerous rooms thanks to its hilltop position, while inside you'll find unusual spaces with curving walls, porthole windows and futuristic built-ins.

Yet even stranger, the home boasts an elevator and a glass skywalk, which lead visitors from the garden to the elevated front door. 

Arkansas is home to numerous zombie-proof properties and this craggy cliff face is just one of them – because inside you'll find a clandestine cave home, built right into the rock itself. This pad is one for someone who wants to live off the beaten track.

The unusual cave home sits inside a 260-acre cavern, high up on a ledge overlooking the valley of Beckham Creek in the Ozark Mountains. The perfect hideaway for an apocalypse or invasion, the underground home is almost entirely hidden from the outside.

It boasts a natural aesthetic, with four bedrooms and four bathrooms across its 6,000-square-foot interior. Not suitable for tall folks, this home is a snug fit in places...

Constructed in 2000, this custom home stands out from the crowd. In the city of Escondido, California, the architecturally rare home was built using steel, plaster and a green-tinted glass known as Solexia.

Having been featured in various magazines, this head-turning property boasts one main focal feature – a central, double-sided brick fireplace that resembles the Eiffel Tower.

Step inside and the chimney takes centre stage in the lounge too. The property spans 2,138 square feet and has three bedrooms and two bathrooms, as well as open-plan living areas decorated with concrete floors, exotic woods and an abundance of glass.

Despite its divisive aesthetic, the house sold in August 2021 for a pricey $1.1 million (£880k).

Described by some as an 'architectural gem', this divisive post-modern home was designed by the Canadian architect Clifford Wiens, and while some adore its futuristic UFO-style exterior, others aren't too keen.

The property was built in 2009 for Wiens' daughter and remains the only home the iconic architect ever built in America. 

In the Wheat Ridge municipality, the property spans almost 8,500 square feet and offers five bedrooms and some truly awe-inspiring interior spaces.

Like a striking sculpture, the home boasts a cantilevered staircase that wraps around an elevator, one-foot-thick slab concrete floors and numerous exposed columns that add to its unusual aesthetic.

Interior design is a personal thing. While some people love minimalism, others enjoy loud patterns and all-out drama. Yet some homeowners have niche tastes, as this Connecticut house proves.

Nestled in the sought-after neighbourhood of Avon, the spacious property has all the hallmarks of a great family home, but once you step inside you'll see that it's not child-friendly. 

Built in 1962, it's akin to the set of a truly terrifying horror movie. The home's interior is decorated with custom-made furniture, while every wall offers unusual paint effects that resemble blood splatter patterns.

The dining room even comes complete with an entire wall of underwear and if that wasn't bad enough, the kitchen features cabinets that look like they're covered in broken glass, while the walls are smeared in blood-red paint.

This mushroom-like home was built in 1989 and can be found in the city of Lewes, Delaware. Quirky and characterful in equal measure, it offers angular walls, a huge roofline and hardly any windows.

We're sure some will love it, but this contemporary property wouldn't appeal to the masses...

Luckily, when you step through the front door, things improve. The interior spreads 1,800 square feet and offers a bright living room, a kitchen, three bedrooms and two bathrooms. There's also a basement recreation room with an adjacent underground garage. 

Who needs windows anyway? That might have been the question the architect behind this home asked when penning their final design. In Pensacola, Florida, this weird and wonderful A-frame property offers three floors of living space and absolutely no glazing across its façade.

Yet the gable ends of the triangular home are decorated with plenty of windows, which only adds to the unusual finish of the 3,450-square-foot residence. Inside, the design doesn't improve too much and some work is needed to bring the property into the modern day. 

Have you ever fancied living underground? Well, this unusual subterranean property offered one lucky buyer the chance to do just that when it went up for sale in October 2020.

After 184 days on the market, the one-of-a-kind concrete home sold for $235,000 (£187k). Sitting on a five-acre estate, the house can be found in Covington, Georgia, and it's certainly not to everyone's tastes.  

Head through the front door and you'll find yourself in an underground sanctuary spanning 2,418 square feet. The energy-efficient concrete home was constructed in 2001 and boasts an open-plan layout, three bedrooms and three bathrooms, as well as hand-painted walls and pitched ceilings. 

To some, Maui Clifftop House in Hawaii is a true architectural masterpiece. To others, it's an unusual residence in a truly spectacular setting.

Interestingly, the house is one of only two Maui properties to have ever graced the cover of Dwell magazine, and it isn't hard to see why the property has drawn plenty of attention over the years.

The state-of-the-art island retreat sits 600 feet above sea level and is a prime example of organic architecture, thanks to its material palette of wood, bamboo, concrete and glass.

With a 2,175-square-foot interior and expansive glazed walls, the home is dramatic and unique in equal measure. No matter how you feel about this property, there's no denying the beauty of its jaw-dropping views...

Never has a property been so aptly named. The Stair Home can be found in the city of Coeur d'Alene, Idaho, and has one of the strangest exterior designs we've ever seen.

Laid out in ascending floors like the rungs of a staircase, the waterfront house was completed in 2019 and its interior is every bit as unusual as its exterior...

The home's light-filled interior covers just 936 square feet but spreads across five floors. There's nothing normal about the layout or design of this pad and even the bedrooms will leave you shocked – in one, you'll find bunk beds built into small crevices in the wall.

The home's most appealing feature, however, is likely its 900 feet of waterfrontage. The property hit the market in April 2021 for $695,000 (£554k) but was later removed without securing a buyer.

Normally, mid-century modern homes are sleek, stylish and highly sought-after, but this unusual ranch-style home in Cook County, Illinois, goes against the grain.

Built in 1957, the 5,500-square-foot residence resembles a spacecraft that has become lodged in the earth. If you're intrigued by its exterior, then just wait until you see what lies inside...

The unusual time warp home is certainly a fixer-upper and boasts a striking interior layout with futuristic rooms, angular staircases and asymmetrical ceilings.

The custom-built ranch might not be suitable for those with children though, since it also features gaping holes where staircase balustrades should probably be...

While some pieces of architecture divide audiences, others are downright disliked by the masses and Dolphin House in Indiana is certainly one of them. Dubbed "the ugliest house in America" by the New York Post, the OTT building has prominent gargoyles, endless balconies and a mismatched exterior.

The controversial property was originally built as a modest three-bedroom ranch in 1953, but local entrepreneur Jerry Hostetler purchased it and soon created a gigantic, one-of-a-kind mansion. 

Spanning 30,000 square feet, the ostentatious house boasts 11 bedrooms, eight bathrooms and one of the most eye-watering entrance halls we've ever seen. For obvious reasons, Hostetler's neighbours were not particularly pleased with the mansion, which was constructed from five houses cobbled together.

Outside, he installed life-sized mermaids, gorillas and polar bear statues, decorating the interior with textured ceilings, rough rock walls, ornate columns and multicoloured glass blocks.

Tired of the same old four walls and seeking something with a little more edge? Well, how does this bubble home in West Des Moines, Iowa, take your fancy?

Like something from The Flintstones, this bulbous building was built in 1980 and certainly stands out from the crowd in suburbia.

As if the home's black exterior domes weren't enough to frighten buyers away, inside you'll find awkward curving rooms and unsightly décor across the 2,184-square-foot property.

Somehow, the pad squeezes in four bedrooms and three bathrooms, as well as a living room and kitchen. There are hardly any windows, so many of the inside spaces are as dark as they are unappealing.

The state of Kansas is rife with former missile bunkers that would make for awesome homes, but not everyone who buys one knows how to create a beautiful property.

This converted military base is positioned in Eskridge and sits on 32 acres of land. As well as an underground bunker, the estate also boasts a unique above-ground creation, complete with a lookout tower.

Step inside and you'll be faced with a 6,500-square-foot home that's partially underground. The multi-level home is rife with glass, towering ceilings and unusual materials. The doomsday refuge landed on the market in January 2021 and sold soon after for a cool $1.6 million (£1.3m).

They say when attempting to sell a house you should take it back to basics, paint the walls magnolia and keep the décor simple, so any potential buyers can visualise their own belongings in the property.

Yet not everyone takes this advice on board, as the owners of this, erm, artistic home in Kentucky prove...

The historic home dates to 1900 and can be found in the city of Covington, yet all of its period charm has been overpowered by a mish-mash of décor.

Step through the vibrant pink front door and you'll find yourself in an artist's playground. From haunting headless statues to bonkers artwork and paintwork of every colour, this once-elegant residence is now the stuff of real estate nightmares.

Who doesn't love a home with history or a stunning château nestled in the heart of rural France? Well, this modern castle isn't really either of those things.

In the city of Covington, Louisiana, the faux historic home was built in 2017 and was inspired by classic, medieval architecture. 

Offering an impressive 5,000-square-foot interior, the modern castle boasts an impenetrable-looking façade and plenty of fake fortress fixtures. There's a garage door that acts as a makeshift drawbridge and a small pond out front that has been described loosely as a moat.

While the outside is somewhat divisive, the home's spacious and light-filled interior does do a little to add to the home's appeal...

Bubble homes are certainly not for everyone, but there's no denying they hold a certain mystique. Positioned in the town of Kennebunkport, Maine, this uncommon monolithic dome house lies on almost 43 acres of land and is entirely off-grid.

The sustainable home is one-of-a-kind and was completed in 2003. Finished with a rotund façade, oversized windows, hand-crafted woodwork and a photovoltaic electrical system, this is one pad that can't be ignored.

Inside, the 1,477-square-foot home is actually quite modern and stylish, you just need to look past the exterior if you decide to live here. With open-plan living rooms and three bedrooms, the pad is light-filled and cosy.

What's even better, the house can be found on a street called 'Road To Misery'. 

Any lover of the Art Deco period will likely fall head over heels for this unusual home near Baltimore, Maryland. Yet, we're sure many more will be deterred by its mint green façade, glass block windows and crazy colourful interior.

The ultimate time capsule, the mummified home sits on a generous 8,580-square-foot lot and boasts a 1,189-square-foot interior that's overflowing with pastel shades, old-fashioned fixtures and retro furnishings.

Dating back to 1915, the house appears almost untouched since it was constructed and we're here for it. The strange spread hit the market in March 2021 for $239,000 (£190k) and sold a few months later. Clearly, beauty is in the eye of the beholder...

You'd be forgiven for thinking this unusual structure is a storage unit, or even an art installation, when in fact it's someone's home.

Close to Harvard University in Cambridge, Massachusetts, the eye-catching residence is formed from three cubes, stacked on top of each other at different angles, creating a, err, different visual aesthetic...

Designed to look like a shipping container home, the 1,206-square-foot condo dates to 2006 and was formed from marine-grade plywood typically used for boats.

Spread out over four floors, including a hidden basement, the home's focal point is its wood staircase, which connects each level. The pad was listed for sale in 2020 for a staggering $869,900 (£693k), which is an awful lot considering its size and unusual exterior...

When it comes to real estate listings that nightmares are made of, few homes compare to this eye-watering residence in Detroit, Michigan. 

From the outside, Lion Gate Estate seems fairly ordinary, if not a little on the old-fashioned side. But step through the front door and you'll find some seriously scary interior design choices...

The listing agent, Clyde Realty, got it right when they said: "Unique barely begins to describe this one-of-a-kind Grixdale Farms estate."

Dripping in custom features, this 3,212-square-foot house boasts shiny metal cladding, hundreds of decorative statues, mirrored walls, carpeted ceilings and plenty of velvet accents. Talk about the world's most unsellable homes...

We love a characterful home as much as the next person, but this obscure property in Duluth, Minnesota, pushes the boundaries of quirky.

The 2,800-square-foot residence is all about organic construction and raw materials and finds itself situated on a strangely sloping woodland plot. It was built, likely by hand, in 1971, which becomes very apparent when you step inside... 

The snail-like house was created by local builder George Hovland and features textured walls and ceilings that seem to merge into one another.

The interior boasts a sunken living room, a dining zone, an oddly designed arched kitchen and, remarkably, five bedrooms. Many of the living spaces open up to an exterior terrace, while unusual skylights allow sunshine to filter into every room. 

Over in Raymond, Mississippi, you'll find this imposing waterside property. Known as McGee’s Castle, it was built in 1979, but it’s not just the home's individual exterior style that has caused passers-by to double-take.

Abandoned and in desperate need of saving, this dilapidated castle is no shrinking violet...

It's said that McGee’s Castle was built by Dale McGee and originally started out as an A-framed house. Over the years, he transformed the property into a medieval castle, laying every brick by hand. McGee clearly had very particular tastes, because inside you'll find some truly eye-watering décor.

McGee is said to have passed away in 2005 and the estate was listed for sale in 2009 for $699,000 (£557k). After receiving a price cut, the property was removed from the market and remains abandoned to this day.

Resembling a city office block, this colossal mansion can be found in the city of Branson West, Missouri, high above the waters of Evergreen Lakes.

Nestled on 350 acres of land, the ridiculously large property boasts 24,963 square feet of frontage as well as a shimmering glass exterior.

Known as Evergreen Crystal Palace, the palatial glass house hit the market in 2021 for a hefty $80 million (£63.7m). The five-level mansion was designed by architect Dennis Spencer and built for Robert Plaster, the founder of Empire Gas.

Almost untouched since the 90s, the property features a green marble, brass and glass interior, an 8,000-square-foot garage, four offices, 12 guest suites and a helicopter landing pad. 

If you're looking to buy a garage in Montana, then this listing may just leave you disappointed, because instead of a storage facility what you'll actually find is a family home. The futuristic compound lies in Ennis and could never be described as ordinary.

Built in 2008, the 15,500-square-foot home comes complete with three bedrooms, two bathrooms, a kitchen and dining area and a huge great room, all accessed by roll-up, garage doors. What's weird about that?

Step through said doors and you'll find yourself in an equally surreal interior. The off-grid spread is powered by sun and wind and is finished with simple plywood and tiny windows.

The 10-acre property also comes with two industrial-style buildings: one dome-shaped and the other a pyramid. The estate hit the market in March 2019 for around $499,900 (£398k) and sold just three months later.

There are plenty of fake castles across America, which took their inspiration from fairytale estates in Europe. However, some just don't quite work.

This modern fortress in Herman, Nebraska, is situated on a stunning 11-acre riverfront lot, but somehow the property itself falls short of idyllic.

Constructed in 2002, the modern castle spans 4,700 square feet and comes equipped with spacious living areas, six bedrooms and five bathrooms. Yet, décor-wise, there's not much to write home about.

Blending industrial design, like exposed pipes and brick, with log cabin-inspired elements, the home is a mish-mash of tastes and styles. The home's crow’s nest tower, however, offers 360-degree landscape views, so perhaps it isn't all bad...

Why settle for ordinary? That's the question the listing agents of this geodesic dome asked when attempting to sell it. Situated in Boulder City, Nevada, this head-turning home was built in 1980 and boasts an unusual exterior aesthetic. 

Yet the home's unusual façade isn't its only unsettling feature. Step inside this 2,474-square-foot residence and you'll be greeted by some truly mind-bending design choices.

From raw stone fireplaces to hand-crafted staircases, domed ceilings and painted murals, this home is akin to a piece of modern art that not many will be able to understand.

Nestled in the quaint town of Canterbury, New Hampshire, this strange and surreal home could certainly be considered quirky. Described by Realtor as a 'hobbit house', an 'igloo' and a 'Flintstones-inspired house', the unusual concrete dome dates to 1991 and offers a 2,800-square-foot interior.

The three-bedroom home has almost too much personality, thanks to its rough walls, rotund ceilings and structural steel staircases. Listed for $350,000 (£279k) in April 2021, the pad had over 100 showings in less than three days, due no doubt to its unique aesthetic.

By May, the house had sold after the agents received multiple offers – so clearly its unusual architecture proved a hit with some!

This quirky and colourful property is home to American multimedia artist Ricky Boscarino, who also designed the home.

Luna Parc is within the 8.5-acre wooded landscape of Sandyston, New Jersey, and was inspired by the Hundertwasser House in Vienna, Austria, and Gaudi’s Park Güell in Barcelona, Spain. 

The 5,000-square-foot main building houses thousands of absurd and exotic artefacts for visitors to discover. The strange home comprises a home, museum and workshop, which is generally open to visitors several days a week.

Amazingly, this Bart Prince-designed home in Albuquerque, New Mexico, has won several awards, despite its divisive appearance. Positioned on a scenic elevated plot in North Sandia Heights, the one-of-a-kind retreat was constructed in 1989 and hasn't changed much since...

From the outside, the home is all rough brick, sharp steel beams and unusual shapes, while inside you'll find mid-century-inspired spaces with ample glass, exposed timber and stone.

With this quirky home, it's hard to work out if it's ultra-cool or just completely bonkers. We'll leave that decision to you...

Constructed in 1929 to resemble the iconic Mayflower, this boat-shaped home has become a landmark of the Adirondack region of New York. Over the years, the property has served as a bar and restaurant, but today it's a rare house that offers a very different way of living...

The unusual historic home is spread over two floors and offers 1,621 square feet of space. Of course, the interior is every bit as characterful as you might expect.

As well as timber-clad walls and ceilings, the boat house also boasts plenty of nautical touches, from ship steering wheels to fishing nets draped like curtains. 

Everyone wants a home with kerb appeal, but this pad in Raleigh, North Carolina, has missed the mark a little. Formed mainly from old-fashioned glass blocks, this retro home was built in 1981 and doesn't appear to have been touched since. 

Spanning 5,724 square feet, the property is kitted out with animal print furnishings, faux palm trees and plenty of varnished wood. Yet the master bedroom is where things get seriously strange. We'll leave this one to your imagination...

This exceptional treehouse, featured on Zillowtastrophes, was described as "when you want all the stairs of a townhouse but all the insects of a cabin in the woods," which sums up this property.

In the depths of the Conestoga Trail in Ohio, this stacked shack was designed by local architect Gerald Rembowski, who was influenced by the great Frank Lloyd Wright.

While the outside is all about treehouse vibes, the interior is a nod to mid-century modern décor. Inside you'll find redwood panelling, rubber flooring and not one, but seven flights of stairs.

The 3,256-square-foot home is also overflowing the retro fixtures. From shag pile carpets to floor-to-ceiling brick fireplaces, this is a pad for those with imagination. Fun and funky, or fabulously dysfunctional? You decide!

Does your favourite colour happen to be brown? If so, then you'll fall head over heels for this property in Berthold, North Dakota. Dating back to 1975, the timber home is adorned, both inside and out, with chocolate-themed décor. 

Inside, the brown theme continues in almost every room of this ranch-style mobile home. From brown flooring to dark wood cabinets and cladding, it's clear the owners of this pad loved the colour palette of the 70s and 80s.

Even the kitchen is decorated with brown mosaic tiles, while the master bedroom is covered from floor to ceiling with timber panelling. Don't say we didn't warn you...

There are homes around the world shaped like boots, alien space crafts and even toilets, but have you ever seen one shaped like a fishing reel? Well, now you have because that's exactly what inspired this pad in Oklahoma.

Designed by architect Cecil Stanfield, the eye-opening abode dates to 1970 and offers a striking orange and green façade.

The unusual design theme continues inside since this fishing reel-shaped house is kitted out with one-of-a-kind touches. The focal point of the home is likely its eye-popping indoor pool, which boasts 28 curved wood beams that extend to the exterior to form a 25-foot dome made from clear plastic.

Other eye-popping features include its colour palette of blues, greens and gold, and the rock walls of the sunken living room.

With the appearance of a UFO that's accidentally touched down on earth, this spacecraft-inspired home lies in Eugene, Oregon, and is just 855 square feet in size.

Despite this and its rather unappealing aesthetic, the property hit the market in July 2021 for a shockingly high $350,000 (£279k), before the listing was removed.

The home's interior gives no further clues as to why this extra-terrestrial home might deserve such a high asking price. The domed property offers just one living space, a single bedroom and one bathroom.

Exposed concrete walls and floors add to its cold finish, while its tiny port-hole windows make for rather dark and dingy living rooms. 

Incredibly, this angular abode in Lake Ariel, Pennsylvania, was originally built to honour the great pyramids of Egypt. Now, it's a fixer-upper with all kinds of exclusive features.

Constructed in 1984, the house spans 3,819 square feet and offers a pointed roof, sloping walls and tiny windows.

The pointy property boasts a double-height living room, a retro kitchen and three bedrooms. From its rustic stone fireplaces to its numerous shag pile carpets, this 80s house is stuck in the past.

The property sold in March 2021 for $200,000 (£159k) and we're keen to see what the new owner does with the place...

No, this isn't a prison camp. It's actually a custom-built mansion in Rhode Island. Known as Brutaliste sur Mer, the concrete residence sits on two coastal acres close to Little Compton and is sure to divide homeowners and architecture fans alike.

Described by some as a 'Concrete Castle', the fortress-like home offers a 5,648-square-foot interior that is equally as bold in its design.

Constructed in 2016, the eye-catching residence is all about exposed concrete and earthen materials, including birch, maple, terrazzo, glass and steel. Artful or awful, we can't quite decide...

Who doesn't love a strong colour scheme? Well, perhaps there are times when decorative choices can be taken a step too far and this home in Marion, South Carolina, might just have reached that point.

The owners not only decided to paint the exterior of the 1950s home green and white, but they also decorated the surrounding trees to match – because why not?

If the exterior isn't enough to put you off, then the aged interior might well be. Described by the listing agents as a "diamond in the rough," this 2,644-square-foot residence offers four bedrooms, two bathrooms, a pink vintage kitchen and several living areas that all need a serious makeover. 

Have you ever fancied living in an egg-shaped home in the middle of nowhere? Well, this home could be the inspiration you need. Small, awkward and extremely odd, this rural cabin is almost too strange to believe.

Positioned in a woodland in Lead, South Dakota, the geodesic dome cabin was built in 1979 and offers just 692 square feet of inside space. The atypical tiny home offers an open deck, a quirky living room and an upstairs bedroom.

Every room is decorated with angular walls and triangular windows. Perhaps this is egg-actly what you're looking for...

This unusual earth home is in Bethel Springs, Tennessee, and would be the ideal home for any lover of underground living. Described as a 'hobbit house' by the listing agent, the property was completed in 2010 and is entirely covered by dirt.

Inside, you'll find a 1,980-square-foot interior, covered by a curving ceiling. There are three bedrooms as well as an open-plan living room and kitchen and the inside resembles a bunker.

Just bear in mind that if you create or buy a home like this, you'll be responsible for mowing the roof...

Few people are fans of a McMansion, a term coined in America to describe large, mass-produced homes with seriously mind-boggling décor.

This particular McMansion can be found in Port Aransas, Texas, and was built in 2012. Spanning an eye-watering 7,383 square feet, the colossal crib offers a rather unusual façade, adorned with fountains, endless balconies and columns.

Inside, the house is a little more appealing, but with shiny surfaces and garish décor, there's no denying that this property missed out in the simplistic style department. 

The state of Utah is known for its oversized homes, but this property takes grandeur to altogether new heights. Positioned in the city of Saint George, the modern-day castle was inspired by European architecture but it certainly missed the mark...

Encompassing a staggering 17,506 square feet, the palatial property is covered, inside and out, with rough stone. While the exterior is cold and uninviting, the interior is almost too grand to be true.

The entrance foyer alone is enough to leave most intimidated, thanks to its soaring ceiling, endless balconies and natural stone finish. Elsewhere, you'll find an all-black kitchen, a bunker-style bedroom and a games room with a hidden slide, which leads to a pool pit filled with foam.

Known as Grahall Estate, this architecturally masterful home is loved by some and, well, not loved by others. In Proctorsville, Vermont, the custom-built home was constructed in 2000 from glimmerstone granite and took its inspiration from the castles of Scotland.

Grahall sits atop Hawk's Mountain and its breathtaking views are certainly the home's best asset. 

Inside, the home offers 7,410 square feet of living space, spread across seemingly endless floors. There are seven bedrooms and six bathrooms, as well as grand lounges kitted out with circular granite fireplaces and sheets of glass.

While some will consider this house to be a blight on the landscape, others will adore its brutalist exterior and rugged finish. 

Blending dozens of architectural styles in one bonkers property, this imposing mansion in Blacksburg, Virginia, is almost too surreal to be true.

From the outside, the mandala-shaped home has the appearance of a Middle Eastern palace, while inside you'll find contemporary, Gothic and Asian influences. Let's step inside...

Standing proud at 8,100 square feet, this custom-built mansion, which is based on the principles of sacred geometry, was built in the year 2000 and is overflowing with objects.

From antique Chinese doors that were once part of a temple, to decorative glass floors and Italian tiles, it's difficult to know where to focus your eyes with this house. 

At first glance, this round house looks more like a UFO than a family home. Situated on a stunning 85-acre plot in Tenino, Washington, its unusual design was inspired by the Garden of Cosmic Speculation – a sculpture park in southwest Scotland.

Thanks to geothermal and solar systems, the home runs completely off-grid and is said to deliver something for mind, body and spirit...

Named Live Merkaba, the house features six bedrooms and an array of curvaceous, custom-made furnishings that reflect the property's architecture. The living room boasts plush rounded couches and an oval fireplace, while the kitchen has a rotund island with a sleek dark wood finish.

The former owner, Rebecca Oppenheimer, the heiress to the De Beers diamond fortune, is said to have asked her South African architect to: “Think Guggenheim Museum meets spaceship."

How many balconies is too many balconies? Well, with this compact home in West Virginia, the answer is two.

Constructed in 1939, this rundown timber cottage can be found in Belington and is almost entirely dominated by its exterior, wraparound terraces, both of which block the view from the windows and add to the home's personality...

If you can find the front door, you'll be able to access the home's 1,490-square-foot interior, which comes complete with a kitchen, living room, three bedrooms and two bathrooms.

Many of the rooms are painted in vibrant hues, from mint green to electric blue and burnt orange, the owner of this pad certainly has eclectic tastes. 

With a small domed façade and limited windows, this rotund residence is certainly not for everyone. In Madison, Wisconsin, the 1,496-square-foot earth-sheltered home dates to the 1980s and boasts a characterful interior, thanks to its curving roofline.

The two-bedroom house is split over multiple levels and is connected by small flights of stairs. There's a sunken living room, a vintage kitchen and a single bathroom. From shag pile carpets to its antique furnishings, there's plenty of retro charm in this one-of-a-kind home.

When house-hunting, does structural integrity sit high on your list of priorities? If not, then Smith Mansion in Wyoming might be just the place for you.

Nestled on a scenic plot just outside of Yellowstone National Park, this unusual log structure towers up 75 feet and looks as though it could be blown over by even a gentle gust of wind.

Created in 1971, this Wyoming landmark has, for obvious reasons, featured in numerous articles, documentaries and commercials. It's even said to have been considered as a location for several movies.

Entirely obscure, Smith Mansion offers no creature comforts. Instead, the house is formed solely from timber and even the couch is carved from wood.
