A patio is a paved area that’s built directly on the ground. It doesn’t need walls and can be either attached or detached from a building. Patios are usually oriented and designed in a way that perfectly meshes with the rest of the backyard design. Patios can be made out of a variety of different materials, including stone, concrete, brick, tile, pebbles, pavers, pea gravel, or rock. Furthermore, they don’t need safety railings and can be shaped however you want.
