Your scholar can also try the Berlin city government's FIS Broker, http://www.stadtentwicklung.berlin.de/geoinformation/fis-broker/ What might be helpful could be - aerial photo map (Luftbilder) from 1928, - building age map (Gebäudealter) from 1992/93 - Berlin um 1910 - Berlin um 1940 Maybe also the State Library of Berlin (Staatsbibliothek zu Berlin) might be able to help https://staatsbibliothek-berlin.de Hope these can help out a bit.

The usual methods haven’t turned anything up, the largest scale I have seen so far was around 1:25,000. The general rule is to find exceptionally detailed information near the locality being studied. I’m not familiar with the mapping projects and resources of that place and time.
