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

brick wall so no option for cavity sliders gas heaters are already in that middle wall as marked, old heaters i think i need to service them as not sure when its serviced last also has two split aircons on both rooms on the far end no weather seals on entry doors, i can feel cold air is coming under some doors, where can i get the seals or is there someone who can come nd check all doors/windows and seal them tin flat room with not much space in between. I think there is insulation in the middle if not its very hard to do anything without opening up the roof sheets. We have double roller blinds on one side. No curtains on patio door(kitchen).

The second look like they are designed for stairwells so I'd be a bit wary about using them up higher as the light might be a bit "spotlight" and not diffuse enough. I think both styles work with your house design

If you are happy with the walls as they are , its a huge cost and effort to just hide some power points . To a small degree , it will also depend what you want to run . Really power hungry appliances ( 2000 watt heaters etc ) may need new wiring , rather than just hooking into the existing wiring . But like bigreader , I'd look at coduit , extension leads ( if lower power use ) and even multi-boxes -- I have used individually switched brushed stainless 4 way ones ( about $80 instead of $10 beige unswitched ones ) and even mounted them to the wall -- they look quite classy and purposeful . And if all else fails , using furniture to hide leads is a good idea .
