I LOVE exposed brick. I've seen online before that they make super thin "bricks" so that you can cover a wall to give it this look without actually having to live in a true brick building. Would look amazing in the right kitchen or dining room.
Pallet deck with stone fire pit. Dig up a small mote area around the fire pit, put a tarp down, fill with sand and surround the area with rocks to prevent the sand from spilling over and to hold the tarp down. And easy deck idea in the back.
