Shanghai Zobon Real Estate Co., Ltd. purchased Zhuhai Haiyi Hotel at an auction in 2004 and then had the hotel renovated from bottom to top. One floor was added to the building which had existed for over 10 years. Finally, it was converted into an individualized business hotel of 12 floors and 16,000sqm. The renovation required to change interior structures at first. Each floor’s function was reallocated. Moreover, the façade must be redesigned.
