Norman Foster has done about 300 projects over the world and has been understood as a global architect for sustainable design on various areas including urban design, architecture, interior, transport and furniture. The trend of Forster's work which had been changed positively as experimental trials from 1960 has established his design trend for sustainable design. The characteristics of Norman Foster's sustainable design leading the trend of contemporary architecture over the limit of the high-tech architecture is researched through the project report, literature, field study and interview based on sustainability aspects which are social, environment and economy especially. For systematic classification and modern analysis of Norman Foster's architecture, the research is analyzed architectural characteristics on case works focused on architecture and urban design after the middle of 1980 when Norman Foster's sustainable design was emerged clearly. Consequently, the research could be a substantial process for understanding sustainable design as current outstanding ideas which makes Norman Foster overcome his limit of Post-high tech architecture through looking at his spatial identity.
