Hello, I must say I like your MODs a lot, but this one and (PEASENTS HOUSE) it has come to my attention that when placing/buiding it, there are no space/land restrictions, meaning, I can built one on a hill with no problemo. As a result, workers will build the house without evening the terrain at all. So I am not sure if this is a bug that you can look into it. I will provide you with a screenshot.

Hello, this is not a bug, placing buildings on hills require terraforming first - you need to flatten ground a little before you can start building process.

The same thing will happen with core game buildings placed in too "higher places".
