For the car port I would keep it simple and open. Use a skillion colorbond roof attached to the house and timber support posts. Do you want to continue with the Tuscan theme? If so I think either go a whitish colour or a darker charcoal colour for the windows and doors. If you intend to paint the exterior walls then you open a whole other world! The front fence would look amazing out of sandstone if that is in your budget, otherwise what about a stackable stone finish which you could glue into a Hebel wall?

re the floor, what about garage matting tiles, as in photo attached, but lay them in a groovier pattern, perhaps a chevron or 60's pattern, if leaning towards MCM. It may not be any dearer than the cost after getting a tiler in, if laying tiles? Also, you can take them out to clean them if need to and change the look whenever you feel the need!

Very helpful Off to do more homework . Many thanks

metal posts can be bolted to the concrete floor with a metal bracket called a "stirrup" there's a brand called Uni-pier with multiple sizes available at the major hardware stores and then attach sections of plastic lattice (friendlier for attaching plants) ...make sure the posts are installed at standard distances to suit the size of the panels..eg four panels 1200 wide x 2400 tall installed between 5 posts would allow for a wide doorway at one end or two panels could be installed horizontally between three posts with gaps at the top and bottom with a line of big oblong shaped pots for climbing plants and wall hung pots could be attached to the lattice
