We used buff sandstone from Tennessee to create this formal cap. The wall is eighteen inches tall, ideal height for a bench. This wall is level with the deck and extends around to frame the back corner of the patio, where the yard is steepest. Above it all looms Beast Wall, a drystone retaining wall we completed last autumn. These clients have some of the most interesting things we’ve built in any residential setting: Beast Wall, the bridge, the culvert, a semi-circular staircase. It’s fun when the people and the project let us roam.
