An opera house shaped like a fossil, a balancing Jenga hotel made of shipping containers, restaurants in floating spheres reached by skywalks... these are just some of the the hi-tech, science-defying constructions that tourists will be flocking to visit in the not-too-distant future.
The name of the game seems to be more unthinkable, the better. Who, for example, has ever dreamt of staying in a giant balancing Rubik's cube in Slovakia's High Tatra Mountains?
One of the most innovative attractions due to open in the next few years will be found in Abu Dhabi, where the futuristic Saadiyat Island Cultural District will house the world's single largest concentration of cultural assets, complete with its own Louvre and the world's biggest Guggenheim museum, among other completely over-the-top attractions designed to lure culture vultures from around the world.
Hotel designs are pushing all the boundaries, too. Take the giant glass floating snowflake drifting effortlessly in the Norwegian Fjords. The five-star hotel Krystall in Tromso has been designed to push boundaries and at the same time will give uninterrupted view of the Northern Lights.
Then there's the much awaited Garden Bridge in London, which was given the green light at the end of 2014. Once it is built, the public garden and pedestrian crossing will provide a vital new route between north and south London, featuring plants, trees, woodland and meandering walkways - all hanging above the River Thames.
Lovehomeswap.com compiled a list of 50 tourist attractions that we can expect to visit in the future. Many of the attractions are currently in construction, while work on the other out-of-this-world buildings is yet to commence.
