We finished this patio last week. Over 500 square feet, mostly natural stone. There is a section of concrete pavers that we put in as a base for the forthcoming hot tub. Apparently hot tubs are a big ticket COVID item, as they ordered it in July of last year and are still awaiting delivery. This patio is made of Tennessee sandstone and laid dry over a bed of crushed stone. It drains subtly away from the house. A subterranean drain under the patio capture water that percolates through and conveys it around towards the front of the house.
The fieldstone wall that surrounds the patio was already there and is not our work.
