A former political adviser was ordered on Monday to demolish a villa he built after it was ruled an illegal building by the Beijing authority.

Zhang Biqing, the owner of the villa in Haidian district and head of a traditional Chinese medicine chain, is required to demolish the structure within 15 days from Monday, said Haidian chengguan, or urban patrol officers.

The house, on top of a 26-story apartment building in Renji Shanzhuang, was built of rocks, decorated with trees and bushes and covers around 800 square meters, according to a statement from the chengguan provided to China Daily.
