Calmwood Mental Hospital (coming soon) - size?

I got really lucky when I was designing a spot for wolfcastle I used fat tony's compound as a fill in. worked out perfect.


Back to your issue. I find that similar building have similar sizes.

mansions, stores ect

next you should look at the picture. it has a prebuild wall around it. looking at it I would use the bad dream house as a fill in since they look similar
