This amazing aerial image captures the scale and uniqueness of this unusual woodland home. Amazingly, the house was once a former water reservoir and has been lovingly converted into a one-of-a-kind holiday home. 

Although it appears to be subterranean on first glance, the house was actually constructed above ground. With its unusual C-shape exterior, the property wraps around an amazing central courtyard, with towering walls of glass allowing any occupant to take in lovely garden views from every single room.

Named the Woolbrook Reservoir, the property has been likened to something from Alice in Wonderland and features a large, light-filled atrium, a living room, a kitchen, dining space, six bedrooms and four bathrooms, as well as a gym and a games room.

Concealed in the captivating landscape of the San Bernardino High Desert in California, this incredible property was designed to slot right in, while allowing any occupants to take in awe-inspiring views from every single room. Hidden at the base of a soaring peak formed from huge boulders, the wonderful white house is almost invisible in its rugged setting.

Known as Sol to Soul, the holiday home is enclosed by a private, 10-acre sanctuary and lies at the end of a three-mile-long dirt road, past fields of Joshua Trees, making it ultra-secluded as well as hidden from the world. Outside, the property benefits from a saltwater hot tub and a firepit, so guests can enjoy magical moments while taking in views of the milky way.

Inside, the property is elegant and serene, with designer furniture by Christian Liagre, one-of-a-kind Moroccan rugs and curated artwork by local artists. However, thanks to walls of glass, it’s the view that takes centre stage. In 2021, Condé Nast Traveler named the property the coolest Airbnb in California, and we can certainly understand why!

Spain is known for its unique cave homes and this one in the Andalucía region might just be one of the country's finest. Named the Habitat Troglodita Almagruz, the property sits at the base of a rocky cliff and is actually built into the ancient rockface itself. Let's take a closer look...

When you get right up to the property, it’s hard to distinguish between the cliff and the property, thanks to the use of locally sourced, natural materials. The structure is split into six cave homes and has been carefully crafted to provide year-round comfort – no matter what the weather is doing outside.

Inside, each cave house is rustic and traditional, with treated cave walls and ceilings that add to the drama. They all have a living area, kitchen, dining zone and at least one bedroom, while glass doors allow for unobstructed views of the surrounding mountains and terrain. 

Look closely and you'll be able to spot a gorgeous waterfront home. Sitting atop a rocky outcrop overlooking Long Pond in New Hampshire, the cottage is enclosed by White Mountain National Forest and was created to provide the lucky occupier with flawless scenery.

Aptly named The Cottage at Long Pond, the 1,585-square-foot residence benefits from 385 feet of direct waterfront access and a rustic yet cosy interior. It comes with traditional timber panelled walls, painted floors and huge picture windows – as well as modest touches, such as smart home technology, an ice maker and a UV water purification system.

Set over two floors, the property has a reserved floor plan, allowing for amazing views from the master bedroom. On the lower floor, you'll find a living room, dining space and kitchen. But, who would want to spend time indoors when this magnificent landscape is right outside?

Positioned on an elevated plot on the border of Mount Buffalo National Park in Australia’s Buckland Valley, this magnificent mid-century home not only enjoys a captivating panoramic but is perfectly concealed by the soaring trees that surround it. 

Spanning a generous 19,400 square feet, the property sits next to the Buckland River, with waterfalls and swimming holes forming part of its enviable front garden. With four bedrooms and three bathrooms, you can take in dynamic views regardless of your vantage point.

Inside, the hidden home is wonderfully retro. Frozen in time, you’ll find exposed brick walls, wood-panelled accents, large expanses of glass and plenty of unique mid-century touches, like the amazing suspended fireplace that decorates the lounge.

This beautiful, secluded cabin is almost invisible among the trees of Viken County in Norway. Situated not too far from the hustle and bustle of Oslo, the property is known as the WonderINN mirrored glass cabin and boasts a partially mirrored façade that reflects the surrounding nature reserve, allowing it to seamlessly blend in.

The wooden cabin was designed by couple Jeremy and Erle, who, after living in a campervan for six months, decided to move to Norway and start WonderINN – a company that specialises in offering unique homes in the heart of nature. This magnificent mirrored home is just one of many the pair has curated around the world. In fact, they're responsible for creating the iconic Panorama Lodge in Iceland.

Inside, the tiny home features everything you could need for a cosy night away, including a kitchen, dining zone, bathroom and double bedroom. With pared-back interior design and walls of glass, the scenery takes centre stage and blurs the lines between inside and out. The master bedroom is perhaps the most impressive space, thanks to its unobstructed views. Head outside and there's a staggered terrace, a hot tub and an alfresco dining area for soaking up the scenery.

Tucked inside an actual cave in Rockbridge, Ohio, this incredible property is unique and special in equal measure. It was built by hand by owners Bryant and Amy Gingerich, who turned a hollow hillside cavity into one of the world's most unusual vacation retreats.

Known as Dunlap Hollow Cave, the residence spans 1,500 square feet and sleeps six people. There's a large living room, a kitchen, a dining space, two bedrooms and two bathrooms. 

The incredible cave house benefits from plenty of quirky touches inside – notably, its exposed cave walls and ceilings that add real drama to every room. With high ceilings, endless windows, concrete floors and statement furnishings, the home is every bit as characterful as you might expect.

As if part of the trees that surround that, this impressive woodland property is barely there. Nicknamed the Treehouse in the Sky, the timber property lies in Virginia, USA, and is elevated off the forest floor, in order to protect nature as much as possible.

Taking a closer look, the modern structure is like a tiny home and treehouse in one. The interior can be accessed via a steep spiral staircase that leads to a comfortable living area, with a kitchenette. Another spiral staircase leads up to a bedroom with a king-size bed and ensuite bathroom.

With plenty of windows, the resident can enjoy lovely views across the treetops, or take to the exterior deck to really connect with nature. Plus, during the winter months, you can see all the way to Sugarloaf Mountain in the distance. 

This tiny, green earth-sheltered house is located in Atlantic Beach, Florida, and was designed and built by noted American architect, William Morgan, in 1975. Morgan built the unusual property as a holiday retreat and, since he lived next door, he didn’t want the structure to block his view of the ocean. So, naturally, he decided to build it underground – in an existing sand dune. 

It isn’t just one house, though. It’s actually a duplex, consisting of two near-identical, 750-square-foot homes. Due to the mass of sand surrounding the building, the interior of each is kept to a nice temperature all year round, even during the height of the humid Florida summer. Inside, the ultra-cool homes blend mid-century-inspired design details with soaring, curved ceilings that follow the natural contours of the sand dune.

From the street, all you see are two staircases, two concealed doors and a mound of grass. But head round the back and you can take in the unique design of the property, with its huge port-hole windows and grass-covered walls. On top of the dune, there's also a sun deck, where lucky holidaymakers can soak up amazing ocean views. The underground home landed on the market in September 2020 and sold three months later for a cool £1.3 million ($1.7m).

Upon first glance, this small grassy mound appears rather uninteresting, but look closely and you might be able to spot one of the world's most camouflaged homes. Built seven feet below the ground, Edgeland House was inspired by one of America’s oldest home building traditions, the Native American Pit House. 

The idea behind the building is that it's dug under the earth's mass in such a way that it retains 'thermal comfort', while still allowing enough sunlight to come through. Designed by the architects at Bercy Chen Studio, the ultra-modern home was completed in 2012 and features an insulated roof, hydronic heating and plenty of glass, for maximum energy efficiency.

Architecturally unusual, the property sits inside a deep excavation on a redundant, former industrial plot and the purpose of the project was to protect and repair the local ecosystem. The modern masterpiece benefits from an amazing façade as well as some seriously innovative design features, including a triangular pool and private terrace. Inside, the living spaces are generously proportioned, with high ceilings, extensive windows and modern interior design. 

We know what you're thinking – this is just a picture of a barren, desert landscape. But you'd be wrong! Take a second look and you might just be able to spot the outline of The Graham Residence, camouflaged among the rugged landscape.

Secluded on 20 acres in the heart of the Yucca Valley, California, the property is surrounded by weathered boulders, ancient juniper trees, desert oaks and native piñon pines. Its steel and glass exterior was designed to perfectly blend in, making the property almost invisible from both near and far.

Compact, it measures just 1,250 square feet and comes with two bedrooms, a single bathroom, a kitchen and an open-plan living room with a dining zone. Sliding glass doors open the rooms up to the landscape outside, where two large decks and a hot tub can be found. It’s really not surprising that this sleek and stylish home has been featured in Dwell magazine multiple times.

Nestled inside a wild woodland in rural Vermont, USA, this magical treehouse is every bit the perfect off-grid hideaway. Enclosed by towering trees, the timber property subtly blends into its surroundings.

The property sits on stilts and is elevated off the ground, meaning its construction didn't have a big impact on the natural environment. There's a lovely treehouse deck, where guests can take in enchanting views and hear the sounds of the stream that lies just feet from the front door.

Inside, the gorgeous treehouse is every bit as amazing, with all the home comforts you'd expect, as well as plenty of quirky touches and rustic décor. There's a cosy kitchen and living room, a mezzanine bedroom and a bathroom. What's even better, the property was made in an eco-friendly way, with many of its materials reclaimed, salvaged or recycled. This includes the large windows, which were rescued from an old, local schoolhouse.
