The new scheme needs to reinforce the basement and build a super high－rise office building. The challenges of the design process were introduced in details, which includes the treatment and construction measurement of the new and old foundation, the reinforcement of underground wall, column and beam which used for transferring, the method for steel pipe column joints and the application of reverse construction, the consideration of structural durability, the treatment of frame joints and design process of performance－based method. The results show that the structure after the reinforcement and reconstruction can meet standard requirements and satisfy the using function and convenient to construction, and construction period can meet the requirements of the owner.Keywords:high－rise building; foundation soil; steel pipe column; anchor; reinforcement
