We designed and constructed this mortar-set architectural cut flagstone two-tiered patio and spa area. To create the separation of the two spaces we tied them together using a multi-functional stacked stone retaining wall and seating bench wall with a precast stone cap, as well as the step treads and risers. We also gave the spa area a natural dry stack stone face with a chiseled edge flagstone cap to complete this beautiful outdoor living space for our clients.
