DHAKA: 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.
