unfortunately there doesn't seem to be a way to add pictures or drawings. The area is a large rectangle divided in 3. The living room is the far left, followed by dining and then the kitchen on the right. Similar to the house in this link https://www.houzz.com/photos/open-plan-kitchen-contemporary-dining-room-sacramento-phvw-vp~92339 . To add rear ground speakers i would need a stand which I actually have but would not look so good. Also i would have to hard wire cable in the floor coming out of the tile. Not so pleasing visually. One side of the living room is glass panels for the deck and the otherside is with glass to the front yard area.
