The wine cellar project here, located in Sonoma CA, was built and engineered from the ground up. The walls are constructed of CMU blocks, the stone real natural stone veneered on to the CMU walls, the doors are refinished old wood with metal studs, and heavy hardware, On the side we installed the retaining wall with flagstone caps, the pool has a flastone decking. This is a great example of our signature Hardscape Construction.
