I still like my waste treatment facility. It has two computers for crafting and reading by night, a basement that has useable space (and in my case delicious ants), a couple of rooms topside for organizing and storing goodies, and a water supply. It needs to be boiled for any form of safety, but it’s great when you don’t have to leave the house to get water.
Next to no exterior windows, and two ways out. I mean, the north-facing door has glass walls, which is theoretically bad, but I don’t use that room except to quickly check if there’s hostiles outside (Without actually going outside - most things near me in the forest cannot smash the walls down.) I’ve got spikey pits two spaces deep in front of those windows just in case.
I’m considering removing the glass walls and filling in those pits, and making that front room into a very small garage for the ad-hoc vehicle I’m working on. If I do, I will still have two doors and a buffer room between my living space and outdoors. (three doors and two rooms if I use the east-facing exit. It’s going to keep your scent indoors during the night, for sure.)
The only thing I’d like better is to edit that room to the basement (I had to hack to get the door open) so it has tables instead of a pipe along the wall. I keep all my stuff there. Maybe I’d take out that wall piece too so the pipe-hallway and the regular hallway are one room. I just need to not collapse the ceiling while I do it!
