1st house - A very solid build overall, the only thing I would perhaps change is the spread of the fish/herb/meat blocks, Try to have them in one location rather than sprinkled around the house.
- do not use plowed soil/soul sand in a regular dirt gradient, instead use mud
- the net over the firewood inside is bit meaningless
Otherwise I like it
2nd house - Pretty much perfect, the only recommendation I can give is to replace the table drawer for bench drawer block, since that one doesnt have the metal handle and would fit better in a lower class house
3rd house
INTS
- have the carpet in one piece, it will look better and make more sense (dont be afraid to have it cover almost all of the floor)
- do not have storage blocks on places that are hard to get to (via ladder etc...) and limit them to 3-5 per lowclass house (exts included) unless there is more specific reason for them.
-single piston tables are very unstable, having only one leg, id recommend using something simple instead of them (slab with 2 halfdoors, crate, etc...)
-having the sausages hang on a horizontal rope rather than a diagonal one would make it look better and allow another item to hang next to them
Exts: try to use up more of the yards area, right now its mostly grass with very small amount of veggie patches. Increase the amount and size of the patches
- make sure a path always connects to them
Otherwise well done!
