I got an idea that you could get golem court house with dragon mouth cave the inside with a few more rooms. You would get this hosue that is available for 5000 crowns for the plant that gives it at elder or the plant can be dropped by ravens, jotun, malistaire and every boss in trial of the spheres with a 2.4% chance if drop. Edit: This house would be weather controlable and i think its price is reasonable as you might jto get it at all at elder and its pretty ahrd to get something to elder. You get to put enemies in the tower, but you must pass it yourself, or it wont go.
