In 1991, due to a cessation of extension and construction for the Hotel Star Hill, this building was abandoned for 13 years. Based on common sense, old buildings are demolished. On the other hand, according to a theme of regeneration for historical and old buildings, this building has been remodeled with a high-quality structure which cares for the environment through the use of EM technology on almost all of the construction, and for human's health like no one can imagine.
Using EM technology for construction, buildings are expected to have some benefits like "improved endurance", "minimizing the bad effects of various chemical materials", "comfort of living spaces" and "improvement of environmental hazards". In addition, the whole building is resurged by periodic maintenance.
