Dong Dayou (董大酉, 1899 – 1973, also Romanized as Doon Dayu) was a Chinese architect and was the Chief Architect for the Greater Shanghai Plan.
Dong Dayou graduated from the University of Minnesota.: 39 At the time, the city planning approach it taught was strongly influenced by the École des Beaux-Arts principles.: 39 For a short period after graduation, Dong worked as an architect in the United States.: 39
In 1929, the City Planning Commission of Shanghai was tasked with preparing a Plan for Greater Shanghai.: 38 Dong was appointed technical advisor to the commission.: 38 The plan for developing a new city center centered on a Civic Center, the plan for which was awarded to architects Zhao Shen and Sun Ximing in an open design competition.: 39 After a series of disagreements within the Planning Commission over implementing the plan, Dong was appointed Chief Architect for the revision of the master plan and for designing the individual buildings.: 39
In 1935, Dong published the essay "Greater Shanghai–Greater Vision" in the American magazine The China Critic.: 37 Dong wrote that Shanghai "fails to meet the requirements of a modern metropolis," citing its "narrow and crooked streets", scarce open spaces, and haphazard growth resulting in factories and residences built side-by-side.: 37
Ultimately, the Greater Shanghai Plan was interrupted by Second Sino-Japanese War and then ended after the defeat of the Nationalist Government in the Chinese Civil War.: 43
It accomplishes this through attention to native architect-planners, e.g. Lu Yanchi (呂彥直), Doon Dayu (董大酉), and Robert Fan (范文照)
