Is there anyway we can build on top of this patio area and not have to worry about movement over the years. What I would like to do is build a frame out of metal 2 x 4s cover it with cement board, veneer it and build a grill in and put on a granite or tile counter. We would be building a grill in from the left side of the building over to the first post. Then build the bar from the first post on the left to the second post. Or should we just saw cut the concrete out, and do construction as usual. 2-3' deep footer under and build up from there? any thoughts?
