@Soldium Uv unwrapping is no magic.
I gave you the tip in another thread to start with a cube and use seams.
Google Here for Blender , insert your 3D app to get better results for you.
Intersecting objects are no big problem.
Ngons could be one.
When meshing, use reference pictures in any possible case, till you get the right scalefeeling.

When you learn that, then include modular asset creation.
It would let you reuse every single element you created before (roof/wall/door), like lego.
When you mesh houses not modular, then you get, what you see.
When you mesh 3 modular buildings you can create many more variations out of that and could generate a small village with some variation…
I love modular.
Follow the Grid, never brake the rules huh like in reallife
