Input: When it comes to illegal structures, a rooftop villa built by an eccentric Beijing resident on top of a 26-storey residential building puts Henry Tang’s wine cellar to shame. 
  
 Beijing's chengguan, or urban management, officials on Monday issued an ultimatum to a former government advisor, demanding he tear down the sprawling structure that he had built over the last six years on top of his top-floor flat. The rooftop house features elaborate fake rocks, real trees and grass, and covers the entire top of the building. Parts of the structure look as if they could spill over the edge of the roof at any time. 
  
 The bizarre two-storey structure, located in a high-end residential compound called Park View in Beijing’s Haidian district, an area of government institutions and universities, has bothered the building’s residents for years. Local newspapers have identified the owner as Zhang Biqing, a doctor of traditional Chinese medicine and former member of a district People's Political Consultative Conference who owns a national chain of acupunture clinics. 
  
 Disturbed by constant noise from heavy construction machinery working on the roof, water leaks and worried about structural damage to the whole building, neighbours have complained repeatedly to the building management company, local urban management officials and even the police. The new ultimatum, published Monday evening on many local news sites, urges the owner to dismantle the structure himself within 15 days. Failure to comply would result in forcible demolition, it says. 
  
 When confronted earlier by reporters from local newspaper Beijing Morning News, Zhang, who sometimes identified himself as a professor, had said, “Since I dare to live here, I am not worried about complaints. 
  
 “Famous people come to my place and sing. How can you stop them?” the newspaper quoted him as saying about the noise at night. 
  
 Some neighbours who had complained over the years suffered harrassment and threats from the owner, Zhang Biqing, local newspapers have reported. One 77-year-old man was beaten up several times by Zhang and eventually forced to move, it was reported. Police didn't seem to have intervened. 
  
 The community’s property management office declined to comment and phone calls to the Haidian district urban management office went unanswered on Monday. 
  
 The “rooftop garden villa” might not be the only illegal construction in this community, Chinese netizens have found out. 
  
 A property agent posted photos of another apparently illegal rooftop house online in late 2011, featuring a blueprint of a three-storey structure with more than a dozen rooms and a bird’s eye view of a nearby lake. 
  
 The structure, which the agent also called a “rooftop garden villa”, had a total indoor area of more than 590 square metres and an asking price of 15 million yuan (HK$19 million). 
  
 When contacted by phone by the Post on Monday, Sun Jianchao, a Beijing real estate agent who posted the pictures, denied the structure in the pictures was the same one in the news this week, but declined to give more details. 
  
 Some Chinese netizens mocked the rooftop house. “Even the Hanging Gardens of Babylon are overshadowed by this hanging villa in Beijing,” said one Weibo user. 
  
 Others were angry at the owner with one internet user saying, “How can this guy be a professor? He gained his happiness by torturing others.” Many also expressed anger at the failure of chengguan officials, known for their thuggish, often brutal behaviour throughout the country while dealing with unlicensed street vendors, in enforcing the law on the rich and powerful. 
  
 Almost all add-on structures or alterations to residential buildings are illegal in China. However, this hasn’t stopped thousands of owners of top-floor or ground-floor properties from adding rooms, and even floors, to their homes, or encroaching into public space by putting up additional walls or fences. ||||| A medicine mogul spent six years building his own private mountain peak and luxury villa atop a high-rise apartment block in China's 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 they've complained for years that the unauthorized, 800-square-meter (8,600-sq. feet) mansion and its attached landscaping was damaging the building's structural integrity and its pipe system, but that local authorities failed to crack down. They've also complained about loud, late-night parties. 
  
 "They've been renovating for years. They normally do it at night," said a resident on the building's 25th floor, who added that any attempts to reason with the owner were met with indifference. "He was very arrogant. He could care less about my complaints," said the neighbor, who declined to give his name to avoid repercussions. 
  
 Haidian district urban management official Dai Jun said Tuesday that authorities would tear the two-story structure down in 15 days unless the owner does so himself or presents evidence it was legally built. Dai said his office has yet to receive such evidence. 
  
 The villa's owner has been identified as the head of a traditional Chinese medicine business and former member of the district's political advisory body who resides on the building's 26th floor. Contacted by Beijing Times newspaper, the man said he would comply with the district's orders, but he belittled attempts to call the structure a villa, calling it "just an ornamental garden." 
  
 Authorities took action only after photos of the villa were splashed across Chinese media on Monday. Newspapers have fronted their editions with large photographs of the complex, along with the headline "Beijing's most outrageous illegal structure." 
  
 The case has resonance among ordinary Chinese who regularly see the rich and politically connected receive special treatment. Expensive vehicles lacking license plates are a common sight, while luxury housing complexes that surround Beijing and other cities are often built on land appropriated from farmers with little compensation. 
  
 China's leader Xi Jinping has vowed to crack down on official corruption, and Beijing itself launched a campaign earlier this year to demolish illegal structures, although the results remain unclear. 
  
 Demand for property remains high, however, and the rooftop extralegal mansion construction is far from unique. A developer in the central city of Hengyang recently got into hot water over an illegally built complex of 25 villas on top of a shopping center. He later won permission to keep the villas intact as long as they weren't sold to others. 
  
 While all land in China technically belongs to the state _ with homebuyers merely given 70-year leases _ the rules are often vague, leaving questions of usage rights and ownership murky. 
  
 A city in Sichuan province recently caused a minor stir when it was discovered to have cut the length of land leases from the normal 70 years to just 40 years. 
  
 The local government's response to public queries drew even more jeers. Officials posted a statement online maintaining that the law allows for lease periods of less than 70 years and adding: "Who knows if we'll still be in this world in 40 years. Don't think too long-term." |||||

Most people would be content to occupy the penthouse apartment atop a 26-story building in Beijing. Not, apparently, a man identified as Zhang Biqing. The South China Morning Post reports that the "eccentric resident"—a "medicine mogul" who owns a chain of acupuncture clinics—has spent the last six years constructing an illegal structure above his top-floor apartment, and it's a bizarre one. The Post describes it as equal to the height of a two-story structure and the width and depth of the entire building (and then some), an 8,600-square-foot mansion complete with rooms, trees, grass, and bushes. Now, he's been given 15 days to take it all down. This after photos of the "villa" were splashed across Chinese media yesterday, emblazoned with the headline, "Beijing's most outrageous illegal structure." (Zhang, for his part, calls it "just an ornamental garden," reports the AP.) Residents for years have complained—about construction noise, leaks, and potential structural damage to the building as a whole. The story gets weirder from there, at least according to local papers, which say Zhang has beat up a 77-year-old man "several times" after he complained about it.
