The rock garden at the mountaintop villa which is built by a professor on the roof of his apartment building in Beijing, China, 12 August 2013. A medicine mogul spent six years building his own private mountain peak and luxury villa atop a high-rise apartment block in Chinas capital, earning the unofficial title of most outrageous illegal structure. Now, authorities are giving him 15 days to tear it down. The craggy complex of rooms, rocks, trees and bushes looming over the 26-story building looks like something built into a seaside cliff, and has become the latest symbol of disregard for the law among the rich as well as the rampant practice of building illegal additions. Angry neighbors say theyve complained for years that the unauthorized, 800-square-meter (8, 600sq. feet) mansion and its attached landscaping was damaging the buildings structural integrity and its pipe system, but that local authorities failed to crack down. Theyve also complained about loud, late-night parties. The villas owner has been identified as the head of a traditional Chinese medicine business and former member of the districts political advisory body who resides on the buildings 26th floor. Contacted by Beijing Times newspaper, the man said he would comply with the districts orders, but he belittled attempts to call the structure a villa, calling it just an ornamental garden.
