You can roll out gingerbread dough into rectangular sheets for walls, cut out windows, and bake. Same for the roof. When done you can fit them together with icing 'glue' and paint them with colored icing. First decide what size and draw each piece (front, back, ends and roof on paper such as typing or computer paper and fit them together to see how it will look when completed. You can also cut out shingles and 'glue' them in place after the rest is assembled. Use the paper pattern as a guide for cutting each piece out of the dough before you bake it. Decorate with icing and decorative candies.
