I think a feature wall would be fantastic. Given the height of the ceilings - I think the color would look fantastic!

Can you add more nails to better attach the VJs to the studs behind? Or use a smaller strip of wood?

When you render the bricks I would consider leaving some of them exposed here and there - that reminds me of old Tuscan buildings! I would include some large terracotta pots with olive trees or lemon trees, also as others have suggested some brightly coloured geraniums in hanging baskets against the wall or in terra cotta pots. Here are a couple of shots of my back deck (which isn't looking its absolute best) but to give you an idea of the large pots and colour. You have a beautiful spot to work with good luck! Sue

Hi dolly 7, The shelving unit is constructed off the wall in front of the the cavity and sits on the floor. You would only need to fix it back to the wall so it doesn't come forward. It would not be good to suspend floating shelves on this wall unless it had a back panel going to the ground. See pic examples. Sliding doors were installed onto an archway first. Wall unit built in front of sliding doors as cabinet. For holding weighty items on adjustable shelves, try to keep the width of the shelves to a minimum i.e. 50cm wide x 18mm thick, otherwise they will bow. If you increase the width, you will need to put a shelf pin in the middle at the back. For floating shelves, back panel should go to the floor if wall has minimal structure.
