Entrance lower than patio/deck?
We enclosed a former carport to make a "garden room" with walls lined with windows that look out onto our garden. On the end of the room where the doors are, we step out into a shade garden under our large live oak tree. The slab level is the same as the ground outside (to previously let a car drive out). The ground under the tree has become very unlevel and lined with roots over the years. I would like to make a patio or deck around/under the tree, but am concerned that the level of the deck/patio would be higher than the slab of the former carport, now garden room. Has anyone ever tried making a patio/deck higher than the entrance way? Or any suggestions on how to approach this idea?
