The best patios, no matter how simple, modest, or elaborate are in the eye of their creator. So even a small gravel floor with a few chairs tucked behind the shed can be the perfect patio.
Economically, this is one design idea that would fit most any budget. And with a little more attention to detail, separation of elements, and planting ideas, it would be suited for more visibility and still be cost effective. Good landscape and garden design ideas don't have to be expensive.
