王府井商业楼的设计,早在1979年4月就完成了,由于拆迁,重新分配等问题,一直到1981年10月才正式开工。原来设计的是服装店、眼镜店和钟表店三家合用,后来钟表改为照相器材,尤其是首层连通的大厅,从中间一隔为二,这样的变化,使位于中心的吊楼梯,变成为偏于一隅的边楼梯,失掉了原设计的意图。营业厅也缩小了,上面几层的使用功能也作了相应的变更, The design of Wangfujing Commercial Building was completed as early as April 1979. Due to the problems of demolition and redistribution, it was not until October 1981 that the construction started. The original design was a combination of a clothing store, an optical shop, and a watch shop. Later, the timepiece was changed to a photographic equipment. Especially the first-floor connected hall was separated from the center by two. Such a change made the central staircase become For the one-sided staircase, the intention of the original design was lost. The business hall has also shrunk, and the functions of the upper layers have also been changed accordingly.
