Architecture Center Houston will host the 13th Annual Gingerbread Build-Off. Competing teams will create 100 percent edible, architectural masterpieces using gingerbread, candy, and all sorts of other sweet treats (of which leftovers will be composted). More than 4,000 spectators are expected to attend and cheer on the teams, play in the kids' construction zone, Scavenger Hunt, and see Santa.
