I did this for my town's annual Gingerbread contest, in conjuction with a historical restoration of the Abigail Adams Birthplace, circa 1685, located in Weymouth, MA. Won 1st place. Probably not very impressive to those who don't know the real house, but I worked hard to get it to look exactly like the real thing. 100% edible. House is gingerbread with Royal Icing siding (piped with a petal tip). Roof is gum paste shingles hand-painted to look weathered (you can't tell in this pic). Windows are leaf gelatin. Walkway is Trident gum "bricks."
