Great guide! Finally some tips to make my houses look better. Thanks!
I'd suggest having "wooden beams" in your walls every few blocks. Ebonwood wall painted brown would be the best way to do it imo.
Not bad for something simple, a great way to start off. I'd suggest walling in the "courtyard" in the lower center with glass walls to prevent spawning there. Also using different materials as you gather them to touch up rooms and make them look fancier such as using Planked Walls in some places or getting a different type of wood for support beams.
I'd say put some paintings and banners here and there. There's also the option of putting mugs and stuff on the bar and bar tables along with using platforms as shelves for all sorts of things.Compare it to other builds
There can be improvement I am just not sure how
