Hello Alessandro,

The OSMNX package allows you to add buildings. Check this out:

https://github.com/gboeing/osmnx-examples/blob/master/notebooks/10-building-footprints.ipynb

The only problem is that there might not be enough information for every building/house. This fact probably varies between cities. For example, I would imagine that there is tons of building data for the City of New York but for smaller towns the building data might be scarce.

If you figure out how to add bodies of water let me know.

Regards,

-Frank
