Hi,
I tried to find information on this prior to posting, so I hope someone here can help.

I bought the half-timbered cottage exterior for my small home originally and relocated recently to a medium size House.
If I change the exterior now to something different, will the half timbered stay a medium House size to be used again or go back to small cottage in my inventory?

I don't want to make a costly mistake! Thank you in advance!
