We called it "The Wizard's Shop" (17x19) and this is an ideal map for an adventure in which players have to visit a building with lots of magical objects and traps.
The map of the house has many floors versions (gridded and gridless, snow, fire, day, night, rain). Additionally, we have prepared 50 assets (PNG files) that you can use during your next Roll20 session. Enjoy!
