Five layers of 9x13 cake with one styrofoam dummy at the bottom. The front piece with the arches is also styrofoam. The roof is Rice Krispie treats covered in fondant spanish tile. It's all fondant, except for the balcony railing and flower boxes which are chocolate- I wanted something to look edible. :-) The was for a housewarming- I call it my "Salvadore Dali" version of their house, since the fondant did not cooperate and parts were buckling and sagging.
