Cheongna City Infinity Tower [ 450m | 1476ft | pro ]

(CNN) -- For architecture buffs numbed by the ongoing global battle to crank out record-breaking tall buildings, here's something innovative to spark the imagination.

The South Korean government has granted approval to begin construction on the world's first "invisible" tower.

Designed by U.S.-based GDS Architects, the glass-encased Tower Infinity will top out at 450 meters (1,476 feet) and have the third highest observation deck in the world.

The project is backed by Korea Land & Housing Corporation, a state-owned land and public housing developer.

The invisibility illusion will be achieved with a high-tech LED facade system that uses a series of cameras that will send real-time images onto the building's reflective surface.

It will be built just outside of Seoul near the Incheon International Airport.

Neither the developer nor GDS have released a target completion date.

The development will reportedly be used primarily for leisure activities. It will include a series of observation decks, a movie theater, roller coaster, water park and numerous food and beverage outlets.

Though height isn't its main selling point, Tower Infinity is no slouch in the vertical department.

When completed, it's expected to come in sixth on the list of the world's highest towers, behind Tokyo SkyTree, Guangzhou's CantonTower, Toronto's CN Tower, Moscow's Ostankino Tower and Shanghai's Oriental Pearl.

The world’s first invisible tower is being built in South Korea—and once completed it will become the third highest observation deck in the world. The invisibility illusion will be achieved thanks to a reflective façade equipped with LED technology that will work as a reflective skin—a sort of invisibility cloak that will blend the tower with the skyline.
