Hmm... that's a very interesting question. I'd like to know too 
maybe it's TianXiang building(天祥洋行大楼),1917, designed by Palmer & Turner Architects and Surveyors(公和洋行). It's the first steel framing house buiding in Shanghai, I guess it's also the 1st one in China.maximus-decumanus said:I define a skyscraper as a building which is made of steel and concrete that has floors, walls, windows to enclose space to house people. However, the definition of a skyscraper does not apply to transmission and communication towers. According to this criteria, the first skyscraper in the world was Home Insurance Building built in Chicago in 1885, because it used steel framing. And I am a bit confused which one was the first one in China.
