Gingerbread house fall down

[xiphias]

So, I've been making a gingerbread house. It's nifty, except for the part where it falls over every time I try to glue the roof on. I think I'm about to give up, especially as Lis appears to be of the opinion that, if we DON'T build the house, she can eat it NOW, while, if we DO build it, she doesn't get to eat it until late January or early February.

First, use royal icing. It's much like regular icing, but it has egg whites in it. Second, let the walls dry before adding the roof.

We are using royal icing, and I let the walls dry for about three hours before adding the roof. Then the whole thing fell apart like a gas explosion.

How thick are the walls relative to the roof? And do you have extra gingerbread pieces or anything you can use inside to help provide structural integrity?

I had to deal with all these kinds of issues when doing pastillage projects in pastry class, so I feel your pain.
