As owner of 3 DLCs i am a lil bit dissapointed, when making a new character it takes a lot of time to be able to build up nice looking houses. My suggestion: make a version of the wall themes which cost equal to the sandstone walls and share their hitpoints.
Also an halfsized foundation would be nice to make rooms with -lets say 3 stairs downwards into an lower area of the room…
I would love to se some special blocks for building up ponds and pools. some cascadestairs etc to it would be nice too.
