The window part on the left is 3 tiles wide; the one on the right is 2. /OCD
Anyway, I'd have some ideas, sure, but it'd be hard to write down all the stuff floating in my head, and besides, you should give it a go yourself! You might surprise yourself.
It's not that bad. You just have to add one extra row of boreal wood walls on the left side OR add one extra row of glass on the right side.Damn how did i made such stupid mistakes, i'll gonna rebuild it, but thats fine, maybe a new idea will come up
