Broad Sustainable Building, a Chinese construction company, is aiming to assemble an 838m-tall building in Changsha, a city in southern China, beating the Burj Khalifa in Dubai by 10 metres. What’s more, they’re looking to build the thing – dubbed SkyCity One – in 90 days because, well, why  not.

What’s probably a little more remarkable than the building’s height or speed of construction, though, is the proposed price tag – they’re estimating a cost of about £400 million (ZAR 4.2 billion), where the Burj Khalifa cost £967 million (ZAR 10.16 billion) to put up. The lowered-price tag is chiefly due to the company’s construction method, which has the majority of the building materials prefabricated before they’ve even laid the foundations – hence too the rapid construction time.

I mean, they’ve done it before – they built a 30-story skyscraper in 15 days not too long ago.

Safety concerns notwithstanding – what with Chinese skyscrapers being mildly prone to collapse during earthquakes and such – Changsha authorities have green-lit the project, with BSB waiting approval from the central government. In theory they could start construction as early as November, and be done by early 2013.

Oh, and the architect designing the thing is from Dubai. Which they can’t be too happy about.
