Hi Christina, I'm glad you like the massive slabs we installed for this home. The lower slab actually has a relief cut into it to accept the angle irons we cantilevered into the masonry chimney to support it, and to reduce weight. Tricky detailed work. This was supplied and detailed for us by our local source: Marenakos Rock Center in Issaquah Washington. Their ability to acquire stone, fabricate to specifications and help with tricky deliveries is second to none. Most of the sales people there "Talk Rock" with a deep background and unparalleled knowledge of Stone. They even teach incredible classes that far surpass any one person's knowledge. Oops, kind of a mini commercial, but they really are great.
