BEIJING (AP) — Beijing authorities are planning to demolish on a bizarre rooftop villa embedded in rocks, trees and bushes that allegedly was built illegally atop a 26-story apartment block in the capital.

Haidian district urban management official Dai Jun said Tuesday that authorities will tear the 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 a response.

Newspaper reports on Tuesday said that neighbors have repeatedly complained about the fanciful villa that covers an area of 800 square meters (8,610 square feet). They said that it has damaged pipes and the building’s structural integrity and that the loud, late-night entertaining that goes on inside keeps them up at night.

Reports said the structure belongs to a traditional Chinese medicine mogul.
