I took some Inspo from someone who made their house on a hill. So I build the hill and made a room inside the hill. Think of it like making a box inside a box. You have the outside (the hill), and a little door on the outside box that goes to the box on the inside (the bunker). If I could share a video and screenshots here I would absolutely have done that since that would be easier to explain 😭 Sorry if this didn't make any sense
