There are a wide variety of options for deck designs including
attached
freestanding
multi-level
corner styles
octagon, and more.

Patio cover and deck designs vary widely dependent on the desires of the home owner and how much openness they want. Patios can be completely enclosed with options to open with screens or slide outs. They can also be partially open with pergola-style. Those that are covered can use a style like their home (with shingles) or other products.
