I made the dumb mistake of putting all the furniture on a single layer, so If i were to simply move the grid layer above that it'd be on top of all the tables and benches ect, also I agree entirely about supports for the overhang. I also think the ground texture beneath the overhang should be different as well. The fireplaces are there but may be difficult to spot because I made the map so small.
Just cut the rug from the furniture layer and paste it into a new rug layer.
