Okay... So damaged or burned small cottage. I'm going for burned myself. However I haven't had the time to add the char and smoked damaged paint to this piece yet. But I'm posting it as is, maybe change out the pictures when I get that done. Please post your makes so we can all see how you decided to paint/decorate your damage. As always, very simple design. I know there's prettier more fancy burnt or damaged buildings on here, but I like to keep things simple.
The roof has an overhang that comes over the wooden walls. This allows it to stay on and aligned when you want it on, and the ability to remove it when you want access to the interior. The other three parts glue together easily.
The roof may need some support. I use Cura 4.0 and put my supports at 64% overhang. This added support to enough of the open area of the roof and the lip of the roof that hangs over the walls, without filling the entire roof structure.
