Re-did fly around model to correctly show rear decking and landscape idea, We have are about to start ground works

Gorgeous Mediterranean area, and I can imagine just how stunning it would be with a fire pit in winter time. To keep with the style, keep sun out yet avoid creating an enclosed feel shade cloth is the best way to go. If you wanted something easy to put up and take down, I agree a gazebo would work really well, like the one below: These are some DIY solutions - you can usually pick up these products from your local Bunnings, or learn more about them online. Plenty of colours, sizes and shapes to suit your space, too! Hope helps - can't wait to see what you decide to go with!

Perhaps it is just the limitations of photography, but to me it seems really shut in and as though the trees are keeping me away/baring the door. I would not want to go and knock on that front door.

The silver will look quite good with your colour scheme. I would probably change some weatherboard for Scyon Axon just to change it up a bit. Also use Scyon Axent for architraves and wall corners. Don't forget eaves and veranda ceilings, etc. as a really nice looking feature use HardieGroove or maybe even some timber to break up the acres of painted surfaces.
