The 1939 map shows the footprint of this double property No. 214–216:
It was curious to see the residence of the most formidable gangster in Shanghai, so I looked closely at the supremely detailed aerial shots posted by the flickr acount China in Old Days:
The houses in front are twin courtyard mansions in traditional Shanghai style, behind a high wall, with a single gate, a big shared yard and a garage. Behind them, also on the property, there are twin three-story mansions in another variation of Shanghai style, with balconies all along the facade.
This property is wall to wall with the one of Zhang Xiaolin 张啸林, Du's partner in crime. Their names appear regularly in the street directories for 1934–1939. In these two residences the very respectable gangsters held luncheons, tiffins and dinners for government officials and business elite.
According to Frederic Wakeman's Policing Shanghai, "At this same time Du purchased Portuguese citizenship and made the French Concession his own personal headquarters. In 1925 he and Zhang Xiaolin together built a three-storied western-style residence divided into two screened off areas on a large two-mu lot on Rue Wagner in the French Concession. Each of Du's three wives had her own floor in the house, and when Du later took a Beijing opera singer as his fourth wife she had to move into a separate residence at Rue Lafayette. The first wife, whom he married in 1915, was unfertile and they had to adopt a boy. The two concubines, both from Suzhou and fifteen years old at the time, were originally given to Du by friends; they bore him six sons. His fourth wife gave birth to a girl."
On August 14, 1940, Zhang Xiaolin's former bodyguard shot him in front of his home, at 214 Rue Wagner.
One website claims this photo is of Du's mansion prior to its destruction, but it looks a lot more like the Donghu Lu property:
