A directive released on Sunday by China’s State Council sought to ban all the bizarre architecture across the country and bring about a uniform skyline. The State Council is pursuing a past pledge to bring an end to the trend of unusual buildings.

“Bizarre architecture that is not economical, functional, aesthetically pleasing or environmentally friendly will be forbidden, while construction techniques that generate less waste and use fewer resources, such as the use of prefabricated buildings, will be encouraged,” the Time quoted a state media report.

The State Council is emphasising in the construction of buildings that are “economic, green and beautiful.”

Chinese President Xi Jinping delivered a speech in October 2014, calling for an end to the unconventional buildings while welcoming morally-inspiring architecture. China’s State Council reiterated the President’s wish by declaring that whacky designs on buildings, such as, Guangzhou Circle or the Gate of the Orient in Suzhou, to be lacking character and cultural heritage and thus they are needed to be banned.

“Bizarre architecture that is not economical, functional, aesthetically pleasing or environmentally friendly will be forbidden, while construction techniques that generate less waste and use fewer resources, such as the use of prefabricated buildings, will be encouraged,” the State Council said in a statement.

Over the last few decades, a number of buildings with unusual and odd designs have been raised across the country, especially in Beijing and Shanghai. These architectural ventures are a part of the decade-long construction boom that took over China.

The directives on restructuring China’s skyline came as a result of high-level talks held two months ago to deal with the problems of rapid urbanization. A similar talk was held in 1978 when only 18 percent of China’s population dwelled in cities. The number has now risen to 50 percent, the News Corp reported.
