Deep gray and all the other accents in silvery old wood and cream. This will add drama, allow the other elements to bring ion light and set off the concrete wall as a true feature. If you want light instead of drama, then go for a very pale beige stone. It will echo stone colours in both the concrete and rocks...

I don't know how hot it gets in Auckland in summer (I've only ever been to NZ in winter!) but if it gets hot, then go for a pale colour. Dark roofs should be kept for cold places!

Thanks for the suggestions. I will definitely try to attach rounded tiles where I can to make it more Spanish. Also love the idea of attaching Spanish style tiles to fronts of steps etc. I will definitely do bright contrasting front door, and I really like the window flowers idea to break up all the walls. Landscaping is my strength, so got that sorted, and will begin that first. There is too much focus currently on parking spaces, and not enough on outdoor living. What do you guys think of this colour. I am happy to paint over the aluminium windows with whatever colour would suit best. Thanks very much.

I would like a soft white.. a white that won't turn yellow.
