From the outside, this concrete tank doesn't look like much, but once you step inside you'll be blown away by its dazzling interior. Originally built in the 1930s, the structure supplied water to the surrounding area, until it was decommissioned and left vacant. Positioned on Pilcher Hill, in the city of Gympie in Queensland, Australia, the unique building has now been converted into an extraordinary home.

Known as The Reservoir, the historic commercial space was renovated by owners Ray and Bev Meads. The luxury home spans 10,376 square feet across three floors and is kitted out with heritage architectural elements and breathtaking views. Key features include curved concrete walls, corrugated steel accents and exposed brickwork. We're sure you'll agree, this unique property conversion is truly awe-inspiring. 

The weird and wonderful home comes complete with four bedrooms, three bathrooms, a huge centralised kitchen, numerous sitting rooms, a powder room, study alcove and laundry space. There's even a penthouse level, which boasts jaw-dropping views as far as the Pomona Mountain. The luxurious master suite is decked out with a walk-in dressing room and ensuite, as well as panoramic vistas.

The home's luxurious basement offers a workshop, wine cellar, gym, movie theatre and garage, as well as dual remote-controlled entrances. Outside, you'll find an in-ground salt-water swimming pool and a fully fenced backyard that embraces the curves of the surrounding landscape. In July 2019, the stunning contemporary home sold for AUD$800,000, or $577,000 (£432k), which we can't help but think is an absolute bargain!

Blending mid-century modern and Craftsman architectural styles to dazzling effect, this curving crib in the city of Healdsburg, California, is truly one-of-a-kind. Blending eye-catching modern elements and a picturesque rural setting, this unusual home is a fusion of old and new, innovative and rustic.

Built in 2000, the custom-build home sits on more than 36 acres of land in its own private valley. Carved into the hillside, it offers 2,705 square feet of inside space, encompassing three bedrooms, three bathrooms, a living room, gourmet kitchen, dining zone and plenty of cosy nooks for curling up with a book or soaking up the surrounding scenery. 

Of course, there are plenty of eye-catching architectural details throughout, too. Notable elements include the home’s wood beamed ceilings, rotund walls and custom built-ins. Head upstairs and you'll be greeted by a truly spectacular hallway, adorned with a UFO-like circular skylight that allows natural light to flood into every living space.

Outside, you'll also find a stage for hosting live music, an outdoor seating area for up to 20, numerous idyllic creeks, a barbecue zone, a shed and a 1,000-square-foot studio that would make the ultimate home office set-up. In July 2021, this curving Craftsman hit the market for $1.7 million (£1.3m) and it's still for sale right now if you fancy living in a home with plenty of character.

Designed by Oliver Hill in the 1930s, this Grade II-listed modernist house sits along the English seafront in Frinton-on-Sea, Essex. Aptly named The Round House, the pad recently underwent an extensive renovation and now offers 2,108 square feet of spectacular living space within its circular walls.

The large entrance hall on the ground floor leads through to a curved dining room at the front of the house. Panoramic windows line the wall, offering spectacular coastal vistas. The retro kitchen has been opened up to create a bright space, complete with curved pastel worktops and appliances that playfully reference the rotund structure of the house.

The futuristic home boasts three bedrooms and two bathrooms, all of which enjoy unobstructed views across the seafront. Key design details include the home's arched windows and doorways that reflect the building's free-flowing curves, as well as Art Deco mosaic floors and a sub-tropical mature garden.

The perfect fusion of style and functionality, the breathtaking beach house was built as part of a 1930s development, dubbed London's Long Island. While only 40 of the intended 1,100 properties were finished, there's no doubt that The Round House is the area's most enduring modernist masterpiece. With its hot tub, wood-burner and soft pastel hues, this outside space conjures up images of Miami's South Beach.  

At first glance, this structure looks more like a UFO than a family home. Situated on a stunning 80-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 delivers something for mind, body and spirit...

Named 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 bathrooms are similarly styled, with circular shower enclosures and oval tubs where you can soak up the views while you... well, soak!

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". The unique structure is formed from various bisecting shapes, including stars, pyramids and cylinders, resulting in egg-shaped rooms and UFO-inspired details.

You'll find plenty of unique features outside too, including a 3,000-square-foot barn that's ideal for hosting guests. Elsewhere, the sustainable garden features a saltwater pool, an archery range, a helipad and a sweeping vineyard, so there's no shortage of ways to while away the hours. 

Known as Oculus, this mid-century gem was designed and constructed in the 1960s by the iconic Australian architect Frank Fox. The breathtaking property boasts a distinctive circular façade and is characterised by rotund walls and curving sheets of glass. 

Nestled on a 10,000-square-foot plot, Oculus is situated in Sydney, Australia, just a short drive from the area's best beaches. The perfect oasis in the heart of the city, the property hides a garden sanctuary with a huge swimming pool, shrouded from sight by trees and tall hedges. Inside, you'll find six bedrooms and five bathrooms, as well as lift access to the home's upper floor.

One of Australia's most stunning homes, the nostalgic retreat blends mid-century elements with contemporary fixtures to create airy open-plan living areas. Retractable curved windows wrap around the entire property, offering 270-degree views across the garden, as well as plenty of light and ventilation in the hot summer months.

As well as a state-of-the-art kitchen, there's also a butler's pantry, a home theatre, a wet bar, and a five-car carport with a vehicle turntable built underneath the house. The balcony, which runs around the upper floor, is shaded by an impressive cantilevered steel canopy, while the master suite offers a luxurious spot to retreat to when the sun goes down.

Positioned in the idyllic market town of Stow-on-the-Wold in the heart of the English Cotswolds, Millway Tower is a one-of-a-kind property with a rich local history. The main stone tower is said to originate from 1307 and is believed to have served the Monks of Maugersbury as a sawmill.

Nestled on an elevated one-acre plot, the extraordinary home conversion is the perfect fusion of past and present, combining historic stonework with contemporary sheets of glass. Inside, brick arches, bespoke curved joinery, an integrated BOSE sound system and a top-of-the-line security system showcase the best of old and new.

The home's 4,736-square-foot interior is defined by curved walls and rotund custom furnishings that add to the retreat's contemporary feel. These lines and angles can be seen most prominently in the home's bespoke kitchen, which features an unusual circular island. 

Light, bright and entirely unique, the conversion of Millway Tower was finished to an extremely high standard. It offers four bedrooms, four bathrooms and plenty of quirky details, from exposed stone walls to porthole windows and huge roof lanterns. 

Nine cylinders interlock to make up this retreat on the island of Møn in Demark. A wooden home that goes against the grain, architect Jan Henrick Jansen designed and built the property over the course of five years. 

Inside, the contemporary interior encompasses 990 square feet of impeccably designed living space. The walls are lined with white painted panelling and the floors are covered in small white pebbles collected from the local beach.

Integrated oak furniture and metal fittings offset the white décor and add luxurious touches to the interior. This elegant bathroom features recessed lighting and opulent brass countertops, while the gold-hued metal carries across to the open-fronted shower enclosure too.

The rustic woodland house is located on top of a small mound, surrounded by birch trees. Outside, you'll find two small pebbled patios, which make perfect alfresco dining areas for the summer months. For rent via Urlaubs Architektur, we can't imagine a more idyllic forest sanctuary!

Known as The Mothership, this famous round house was commissioned by late American comedian Jackie Gleason and sits on 8.4 acres of land in the Hudson Valley. Originally used as an upstate getaway while the actor filmed The Honeymooners sitcom in New York, it's become a famous local landmark.

The Mothership revolves around a stunning marble spiral staircase and has a number of amazing design elements, including hand-carved wood flooring and a circular bed in the master bedroom, plus tons of curved storage fitted into the walls.

Previously on sale for a jaw-dropping $12 million (£9.1m), the home also has four stylish bars, an Italian marble fireplace and two outbuildings where Gleason used to entertain his famous guests, including the likes of US president Richard Nixon. How's that for a home with history?

This unique home in the Surrey countryside sits in eight acres of historical grounds and is comprised of two buildings, the 1930s Round House and the converted 19th-century Coach House, which sit just 50 feet apart across a courtyard. 

A modernist masterpiece, the Round House was designed by renowned architect Sir Raymond McGrath and has been recognised as a building of great national importance – it was even awarded the rare Grade II*-listed status. 

Originally for sale in 2016 for $11.9 million (£9m), the house has provided the backdrop for various advertising campaigns and music videos. The six-bedroom property encompasses 6,500 square feet of living space, including an amazing circular living room, library and kitchen. Swathes of windows look out across the breathtaking grounds, which include manicured gardens, woodlands and five ponds.

Upstairs, this rotund bedroom comes complete with an opulent ensuite bathroom and dressing room. Decked out to an exceptionally high standard, the house is brimming with quality materials including marble and copper, proving that unusual architecture needn't compromise on luxury finishes.

Tucked away in a forest in The Netherlands, this round house was specially designed for a family and their beloved dogs. The 360 Villa features a continuous wall of curved glass across the front aspect of the house, meaning that the owners can keep an eye on their four-legged family members even when they're outside.

Inside the unique woodland home, the stylish décor features muted grey tones and hints of natural wood, while an open floor plan connects the living area, kitchen and bedroom. Clever design details are visible throughout, including these ingenious circular skylights that bathe the interior in natural light.

Designed by architects 123DV, the goal was to achieve as much of an open feel as possible without compromising the homeowner's privacy. To this end, the bedroom features a sliding door that can act as a room divider if needed.

The canopy around the edge of the house allows the dogs to take shelter during the cold weather and enjoy the shade on hotter days. To keep the owners in regular sight of their canine friends, mirrors were even installed on the inside walls of the terrace.

This rotund bolthole, designed by Kjellgren Kaminsky Architects, sits in central Sweden on the edge of Lake Liljan. The round structure of the villa eliminates any voids that could leak heat, making it an extremely energy efficient build. 

Part of Sweden's first series of passive houses, the round house is a groundbreaking development in this rural idyll. Inside, the paired-back floor plan positions the living room and kitchen towards the lake, while the more private areas, such as the bedroom and bathroom, are situated at the property's sheltered rear.

Located on the very edge of the woods, the minimalist house features vast picture windows that frame stunning panoramas of the lake and forest. We can't imagine a more breathtaking view to enjoy over dinner. 

Situated on a hillside in the Italian province of Rimini, this circular dwelling is a real showstopper. Designed by architect Roberto Rossi and built by ProTek, the spectacular home rotates 360 degrees, allowing residents to soak up the rolling rural views from every possible angle.

Built on a circular pillar, the rotating home can be mechanically turned to follow the best of the light through the day. The structure's rotation can also be used to position the home's solar panels towards the sun as it shifts, ensuring maximum energy gain.

Inside, the neutral décor celebrates the dwelling's fascinating angles, with floor-to-ceiling windows framing views across the spectacular rural landscape. When it comes to comfort, the interior is kept warm and cosy thanks to innovative hemp-insulated walls.

If that wasn't enough, the dwelling also has some serious eco-credentials. According to its architects, the structure generates all the energy it requires. As well as solar panels, the property has a heat pump and a solar thermal system, which make sure the day-to-day running of the home has minimal environmental impact.

The epitome of a fairytale home, this wonderful property can be found in Saugerties, New York, and was designed and built by artist John Kahn. Kahn was an associate of Jim Henson and collaborated with him on sets and costumes for The Muppets and Fraggle Rock, something that is apparent in the quirky and playful look of this towering abode.

Sitting on five acres of land, the house is located just 10 minutes from Woodstock. The home's original owner reportedly considered it to be a work of art and we can't really argue. The 2,118-square-foot residence was handcrafted from reclaimed materials, including walnut, copper and bamboo, and took Kahn several years to build. From its circular layout to its rustic ambiance, there are almost too many characterful elements to name. 

The home's peculiar shape and ample windows mean natural light enters the living spaces from more angles, resulting in bright and inviting rooms. Every single area is entirely unique and even the entrance hall is imposing, thanks to its beamed ceiling, curved walls and sweeping staircase. Colourful and eclectic interior design elements add to the home's personality, from green floors, to vibrant tilework and vintage-inspired light fixtures.

Spread across five floors, the incredible home offers a rotund living room, a kitchen with custom cabinets that perfectly fit its shape, a basement, three bedrooms and two bathrooms. Balconies and decks branch off from the home's core, allowing for an easy indoor-outdoor flow. A spiral staircase leads to the top floor, which is home to the master suite and a wraparound porch with views of the Catskill Mountains. In August 2021 the house was listed for $799,000 (£599k), and with a sale pending, we'd love to know who snagged this unusual abode.
