Hi , this is my first large Ginger bread house, it has a cardboard center base ( this is going to be in a store front window, Wanted to take no chances)

took 5 basic batches of ginger bread to get it right and it took over 16 hours, but i love it, it is over 24 four inch's high and is all edible, the pool is boiled sugar and foil. ( i would kill any one who tries to even cut into this house) . I would love any suggestion, i want to make one for the center piece for our Christmas dinner buffet.
