London ( CNN ) -- Imagine a skyscraper that cleans the air . You wo n't have to wait long -- two will soon be built in China . The world 's tallest towers , futuristic pink spires that `` breath life '' into the environment , are due to begin construction within two years . The ambitious Phoenix towers were designed by London-based architects Chetwoods and will claim the tallest building title from Dubai 's Burj Khalifa . And the design goes one step further : The towers will be one of the world 's most environmentally-friendly buildings . Stretching up more than a kilometer into the skies above Wuhan , the capital of China 's Hubei province , the Phoenix project aims to clean the air and water from its surrounding areas . It 's expected to become a tourist attraction for both Chinese and international travelers . Chetwoods chairman Laurie Chetwood told CNN the project is more than just an architectural statement . It 's also about preserving the lakes of the region , he said . `` You can imagine the pressure those lakes are under , [ with ] a huge dense city growing around them , '' he said . `` So we thought we could not only attract attention with the towers but also breathe life , literally , into the lakes . '' The architects have looked to the natural world for inspiration , building a `` thermal chimney '' in the center of the taller tower . The chimney , heated by the sun , will draw air from across the lakes and use it to cool the buildings . The air will then be filtered and churned back into the environment cleaner than before . The buildings will do the same with the water , tantamount to `` putting air back into the water like in a typical fish tank ... . but we 're also cleansing the water and putting it back , '' Chetwood said . The towers have also drawn on Chinese culture , reflecting its use of the phoenix as a metaphor . `` It 's two dragons or two birds -- one male , one female -- and we use this idea as a symbiotic idea , one feeding off the other for the benefit of all . '' The taller of the two towers will accommodate a kaleidoscope , turned by a wind turbine , and creating what Chetwood hopes will be a `` wonderful experience when you look up . '' Combined with photovoltaic panels , they produce electricity for the project -- with some spare for the district . The smaller tower will feature the world 's tallest `` green wall , '' or vertical garden , which will climb to the top of the tower . But perhaps the most controversial architectural feature are the huge celestial orbs strung between the two towers , housing restaurants and viewing platforms . The designs are unusual , the `` sort of idea that China embraces , that perhaps somewhere else in the world they think you 're going too far there , '' Chetwood said . The towers will glow in vibrant pink , as a nod to the fuchsia flower . While architects often pivot to monochromatic colors , Chetwood wanted to mix it up with color . Also , he adds , `` I hold my hands up and say I actually like the color and thought it would look stunning . '' Constructions starts in 2016 , and the aim , Chetwood said , is for people to `` have their breath taken away . ''
The world 's next tallest building is being built in China , and the two towers will clean the air around them . The Phoenix project has been designed by London-based architects Chetwoods , building will begin 2016 . Chetwoods chairman tells CNN he wanted the project to be more than an architectural statement .
