When the world last heard of Hunan-based Broad Group, the construction firm was still struggling to win approval to turn a watermelon patch into a 220-storey vertical city.
Now the air conditioning maker turned-modular building group has bounced back from its frustrated attempt to build the 838-metre high Sky City project, to create the 57-storey “Mini Sky City.” And the company says they built the 186,000 square metre (2 million square foot) tower in just 19 days.
Broad Builds Office Tower in Backyard
After local officials in Changsha decided that the Sky City project lacked the necessary approvals (and after the plan to build the world’s tallest building in a Chinese second-tier city received widespread ridicule), Broad Group boss Zhang Yue apparently decided to prove the virtues of his company’s modular building system by tackling something more manageable.
Although modest compared to the company’s earlier plans, Mini Sky City still was built to provide 800 apartments and office space sufficient to accommodate 4,000 workers, according to the company. The structure was originally planned to reach 97 stories, but was scaled back to meet with local air traffic requirements, Broad says.
The new tower was built next to Broad’s factory in Changsha at what the company says was a construction cycle of three floors per day. The company did not indicate what types of tenants might be most suitable for occupying a 186,000 square metre facility on the outskirts of Changsha.
Building a More Sustainable High Rise
In addition to speedier construction, Broad is also determined to make its new building easier on the environment. According to the engineering firm, its prefabricated construction technique helped it cut back truck deliveries on the project by 15,000 trips and reduces construction dust.
Before building Mini Sky City, Broad had already seized headlines by completing a 30-storey hotel project in only 15 days and a three-storey building in only nine days.
