Castaway Stories Jungle Hut Column and Bamboo Jungle Hut Column.
I used the original textures and added a swatch using a modified texture from the outdoor retreat log furniture.
These have no footprint.
So decided to scrap the "walls" look (for reals, used your outdoor rock sculpture to shade a bed until I could afford to build a house that looks like a literal tree (4 levels, super tall walls, all bark wallpaper, etc). I'm crap with building though, but I've had so much fun trying to keep things as minimal/survivor as I could (no tech, tv, etc) with your stuff.
