Not only the height
For example see this, barrack seens more little than houses, more narrow. I think that would be neccesary a rework of building for its new suface.
For example, the stable. Only would be neccesary to increase the size of the underlined building.
It could take up more land in the horse pen and would look good without taking up more space than its 2X2s. The buildings don’t really need to be much larger, just proportionate.
