Futuristic Lux Hotels

Waterworld

Designed by Atkin’s Architecture Group deservedly won the first prize award last year in an international design competition. The 400-bed resort hotel features underwater public areas, guest rooms, cafes, and restaurants. The major attraction is the extreme sporting facilities including a luxurious swimming pool, rock climbing and bungee jumping

Commercial Space Station Skywalker

The concept is a big challenge while it tests inflatable technology and fights to survive in hazardous conditions. Hope it’s made to face the wrath of the meteorites, though the hull of each module is made of three protective layers with an outer 18-inch-thick shield made of alternating woven graphite composite and foam to protect against orbital debris.

The Lunatic Hotel

The Lunatic Hotel (concept) will allow tourists to indulge in low-gravity games with the help of two 160-meters high slanting towers. The towers will be equipped with teardrop-shaped ‘habitation capsules’ which will serve as spaceship like suits for tourists. The 50-cms thick hull made of Moon rock and layers holding water will protect inhabitants from the harsh lunar environment including extreme temperatures and lethal cosmic rays and solar particles. Will this ever materialize? Time will tell.

The Hydropolis: Undersea Resort

The Hydropolis was designed keeping in mind that we’re around 60% water, endeavors to deliver the serene beauty of the ocean in its true colors. Tourists can enjoy their stay in 220 theme suites within the submarine leisure complex. It is one of the largest contemporary construction projects in the world, covering an area of 260 hectares, about the size of London’s Hyde Park. Website

The Apeiron Island Hotel

The Apeiron Island Hotel is a seven star resort with a total floor area of 200,000m². It is 185-m high and boasts of over 350 luxury apartment suites. The building apears to rise from the ocean like a beatiful fountain. Unfortuanately, this is just an artist's rendition of the conceptual resort wit a price tag of $500 million. The artists Torquil McIntosh and Simon Mitchell have few other structures that I think someone will eventually built. Website

The Poseidon Undersea Resort

The world’s first underwater resort will be ready by the end of next year with breathtaking coral reefs where you can literally immerse yourself. Surrounded by 5,000-acre lagoon, the Bruce Jones’ the Poseidon Mystery Island offers luxurious 550 square feet large suites. Website

Aeroscraft: The flying luxury hotel of tomorrow

Aeroscraft is a gigantic 400-ton blimp designed to carry passengers in its spacious luxury cosmos on board. With an area equal to two football fields hangs in air with 14 million cubic feet of helium, huge electric and hydrogen fuel cell powered propellers and six turbofan jet engines. The hotel can accommodate 250 passengers driving them at a speed of 174 miles per hour up to 6, 000 miles. Designer Igor Pasternak has also plans to float a cargo-carrying version too once the project takes off. Website

Foldable Hotel Pods

Foldable Pods are for traveling geeks who find it hard to shun all the amenities of their luxurious life. The pods will be self-sustainable, and guests can choose the images they want to be projected on the walls. When a destination falls out of fashion, whether due to demand or terrorism, the pod can simply be folded up and moved. Now, someone just have to pay to built it - estimates are between $72 to $104 million.

The Hotel Burj al-Arab

Considered, unofficially, the world’s first and only 7-star hotel, the Burj al-Arab is a truly the most luxurious hotel imaginable.
The tallest, 321-metres (1,053 ft), hotel, designed as a sail of a dhow, is constructed on an artificial island 280-metres (919 ft) out from Jumeirah beach. The hotel boasts of the world’s tallest atrium, which is 180-meters (590 feet) tall. Website

The Diamond Ring Hotel

The Diamond Ring Hotel in Abu-Dhabi is a project in the works. I don't have any further information as to when it will be completed.
Dubai is taking the architectural game to a whole new level.

Galactic Suite

The Galactic Suite Designer Xavier Claramunt has tried to imbibe things. The Galactic Suite will have around 22 rooms, measuring 7X4 meters, free of straight lines or angles and huge windows. It is termed as the first global project of its kind, next to Robert Bigelow’s space hotel. Different capsules will act as bars, restaurants, reception, and more. Website
