It's a very big house, It's a shell challenge and I don't know if I followed the rules correctly, I think I did. It's ment to be all base game,maybe a couple items might not, But if I remember correctly all base game, If you used this house can you please upload the family that you used it with. You can use the hastag #ximenassuperbighouse I hope that you enjoy it! #bighouse#basegame#verybig#old
