 Many homes have a concrete porch in the front or back of the house. Be honest though, it's pretty bland and boring, isn't it? One way to help that porch make a statement is to install tile on top of it. But since the porch is exposed to the weather, you'll want to make sure you use the right material. Tiles like slate and ceramic may look nice, but they can absorb moisture causing the tiles to crack or pop loose.
