Through the Fuzzy Delphi Method (FDM), we confirmed that 20 SWOT factors should be considered in developing low-rise steel construction building in Taiwan. The weights of SWOT factors were arrived at through analytical hierarchy process (AHP). Improvements should be made for the weaknesses and threats in developing low-rise steel construction buildings with higher weights. Fuzzy technique for order preference by similarity to ideal solution (Fuzzy TOPSIS) was used to obtain the order preference of eight strategies suggested in this paper.
