Books on Hamburg City Layout?

Does anyone know of several good books covering Hamburg's city layout in-depth in the 1920s?

For my timeline, I'm planning to have a detailed Hamburg Insurrection taking place across the city in streets, buildings, etc.

Specifically, that means working-class districts, key buildings to be potentially used as meeting halls, etc.
 
My German isn't very good, but I'll try to translate the latter page to the best of my abilities.

Thank God for German for Dummies and Rosetta Stone! :D
