Take a seat, fasten your seatbelt and allow an usher to wheel you into a giant eyeball dangling outside of a building so you can take in all of the sights without anyone else present. The exhibit, entitled EYE, asks you to look first at the city, and then at yourself. Installed in five different buildings throughout the city of Den Bosch in Holland, the project by Belgian artists Pascal Leboucq and Lucas De Man features enlarged reproductions of the real pupils of local residents.

EYE is currently installed in a theater, a modern hospital, an old factory that’s about to be redeveloped, a monument and a corporate business. Billed as “an extraordinary audio-visual theatrical experience,” each eye seats one visitor at a time. After taking a seat and entering the eye, they’re invited to relax and take a look. Then, the guide asks them, “What do you see?”

“A city with eyes is a city that looks and shows itself,” says De Man. “No closed doors or shut windows, but open. We gave the city eyes so you can hang in the air above the world and look. Just look.”

The installation will remain in place until November 1st, with tickets available online, and will tour the world in 2015.

Jutting out over cliffs or hovering over impossibly small foundations, these 16 dramatically cantilevered structures seem like they’re about to take off into the sky. With designs that appear to defy the laws of physics, these balancing homes, museums and mountain overlooks extend beyond the usual boundaries to take in majestic views.

Balancing Barn by MVRDV

Dutch architecture firm MVRDV has made a name for itself with wholly unexpected, often gravity-defying structures, and Balancing Barn is a prime example. The glittering metal-clad building looks like someone started to push it off a cliff and gave up, seeming to balance precariously on the edge of the hillside. The structure is 98 feet long (30 meters) and is actually no barn at all, but a home designed to take in the views of the surrounding forest.

Hemeroscopium House by Ensamble Studio & Anton Garcia-Abril

A swimming pool juts out over the grass at the highly unusual Hemeroscopium House by Ensamble Studios. Made of prefabricated concrete built from three massive I-beams, two segments of an irrigation canal and two steel girders, the house took just a week to assemble.

Top of Tyrol Viewing Platform, Austria

The sculptural Top of Tyrol overlook by Aste Architecture is a platform that juts 27 feet over a ridge at the pinnacle of Austria’s Mount Isidor. The oxidized metal structure was designed to blend into the environment as much as possible, seeming to disappear into the rocks during warm weather and meld with the snow in winter.

View Hill House by Denton Corker Marshall

Rather than placing the second story parallel to the first, as is most common, Australian architects Denton Corker Marshall chose a perpendicular approach for the aptly named View Hill House. The architects envision the isolated building as ‘land art,’ a shape that can be reduced to two sticks placed on top of each other and ‘dropped’ onto the landscape.

Five Fingers Viewing Platform, Austria

Five individual platforms stick out of this overlook in the Salzkammergut area of the Austrian Alps, each with a different way to experience the view. One has a picture frame at the end, another has a glass floor, the third has a trampoline, the fourth features a round hole in the floor and the fifth offers a telescope.

Floating Architecture 16 Dramatic Cantilevered Structures

Your head spins, your stomach clenches, your heart pounds furiously. You’re thousands of feet above the ground with nothing but glass keeping you from teetering over the edge in a lengthy and final fall. Do you have the guts to look down? Hundreds of feet in the air, these 13 tower platforms and observation decks – often with transparent floors – offer absolutely breathtaking views of cities like Shanghai and landscape features like the Grand Canyon.

Burj Khalifa Observation Deck, Dubai

You’re never going to get a higher vantage point from a free-standing structure than that attainable at the Burj Khalifa observation deck in Dubai. Unless, that is, somebody builds a structure even taller than this world-record tower, which reaches half a mile into the air. The observation deck is on the 124th floor of the Burj Khalifa (formerly known as the Burj Dubai) and on a clear day, it provides absolutely jaw-dropping views of practically the whole of the United Arab Emirates.

Stockholm SkyView at the Ericcson Globe

You’ll literally feel on top of the globe when you hitch a ride in one of the glass ‘gondolas’ at Stockholm Skyview, a moving observation deck that travels up two sets of rails on the exterior of the Ericcson Globe Arena in Sweden. Each gondola can take 16 people over 426 feet into the air for an unforgettable view of the city of Stockholm.

Top of Tyrol, Austria

Virtually invisible against the snow in the winter, ‘Top of Tyrol’ was designed to blend seamlessly into its environment and provide a vantage point that most people couldn’t achieve without some serious mountain climbing abilities. Designed by Aste Architecture, Top of Tyrol cantilevers nearly 30 feet out from the pinnacle of Austria’s Mount Isidor, about 10,500 feet above the ground.

Shanghai World Financial Center, China

Before the Burj Khalifa came along and shattered all kinds of records, the observation deck at the Shanghai World Financial Center was about as high as it got. The glass observation corridor, which spans the summit of the building, is half a kilometer in the air – but the faint(ish) of heart can still get a thrill by checking out lower decks on the 94th and 97th floors instead.

Five Fingers Viewing Platform, Austria

Get five different views with five different features in each jetty of ‘Five Fingers’, a viewing platform in the Austrian Alps. The first has a picture frame for souvenir shots, the second a glass floor for that vertiginous feeling, the third a trampoline for the foolhardy (this one is only open for special events, lest tourists bounce themselves right over the cliff), the fourth a hole in the floor to peek through and the fifth, a telescope.

Sands Skypark, Marina Bay Sands, Singapore

On the top of three skyscrapers, 656 feet in the air, Singapore boasts a 1,246-foot-long rooftop deck by architect Moshe Safdie offering an incredible view of Marina Bay. The curving Sands Skypark is shaped like a ship and equivalent in size to the Eiffel Tower laid on its side. Among its most notable features is a 150-meter-long infinity swimming pool, which makes guests feel like they could swim right over the edge.

Landscape Promontory, Switzerland

Designed by Paolo Burgi, Landscape Promontory is a suspended metal platform that almost looks like an insanely oversized, modern version of a carnival ride – except that it (thankfully) doesn’t move. The viewing platform extends out from Cardada mountain in Switzerland and is marked with symbols and explanations that tell of local history and literature.

Willis Tower Skydeck, Chicago

Step out onto the deck of the Willis (formerly Sears) Tower ‘Skydeck’ – an enclosed balcony made almost entirely of glass – and you’ll feel, for a moment, as if you’re about to hurtle to a rather unpleasant death on the streets below. Or perhaps, if you’re the brave type, the height won’t phase you at all and you’ll just be completely entranced by an unparalleled, uninterrupted view of the Chicago skyline.

Aurland Lookout, Norway

You know that stomach-clutching, heart-in-your-throat sensation you get on roller coasters just as you’re coming up to the edge of a terrifyingly steep drop? That moment is drawn out indefinitely at the Aurland Lookout in Norway, a stunning wooden overlook that puts nothing but a sheet of plate glass between you and the countryside below. Designed by Todd Saunders & Tommie Wilhelmsen, the minimalist structure celebrates the region’s natural beauty and exemplifies its spare, modern design sense.

Eureka Skydeck, Melbourne

They named this thing ‘Eureka’ for a reason – it’s about the tamest exclamation that would emerge from your mouth as you walk out onto it. As you look down through the glass floor, you become acutely aware of the fact that you’re nearly 1,000 feet above street level. Jutting 9 feet out the side of the building, the Skydeck offers the highest public vantage point in a building in the Southern Hemisphere.

Grand Canyon Skywalk, Arizona

Stepping out onto the Grand Canyon Skywalk is probably the closest you’ll ever get to walking on air. The U-shaped walkway, considered quite a feat of engineering (or an over-developed eyesore, depending on your viewpoint), extends 66 feet from the canyon’s edge and its two-inch-thick glass floor lets you gaze down 3,600 feet to the canyon floor below.

House on the Rock Infinity Room, Wisconsin

As you emerge from the cluttered depths of one of America’s most bizarre roadside attractions, The House on the Rock, you can clear your head on a cantilevered viewing platform that extends 218 feet over the forest floor. Once you reach the end of the ‘Infinity Room’, which has 3,264 windows, you can look out the final pane of glass, which is set into the floor at the tip.

i360 Tower, Brighton, UK

England’s Brighton Beach will get a 600-foot needle tower with a circular glass viewing platform that can hold 125 people, following years of delays. The i360 Tower – which might get a name change by the time it’s complete – is set to become Britain’s highest observation tower, granting 360-degree views of the coast.
