Install a Sandstone staircase within an existing retaining wall that leads onto a new patio that is situated into a hillside whose infill is held in place by a new boulder retaining wall. The Sandstone stair case is 38 feet long and uses Unilok Brussels block pavers which match the 235 sgft patio and Versa-Lok block for the cheek wall. The fire pit is Castle Rock and the three tiered boulder wall is 45 feet long & 6 feet in height at the highest point.
