I don't know if it's antique or not. We bought it at a church sale 20 years ago in Atlanta. Six rooms plus an attic. A little bit of furniture. Pretty sure it's handmade. There are a few nicks on the trim and shingles. I didn't paint anything because I didn't want to diminish the value if it is antique.
It's over three feet wide (39") and 23.5" deep.
The chimney is 31.5 inches tall and the house stand 28" from the base to the peak of the roof.
