Thanks Anne and I will look at pale grey given the maintenance considerations. I have already paid for a colour consultant who was great but the Reckless grey she suggested for the house render and basalt gutters/fascia and front wall were too grey when we had the render samples put on and while it had a modern look, it was not giving the beach/coastal feel. I will head back into our inspirations paint store this morning to see if I can find the warm grey colours that have the most similar colour make up to Dune, and go from there. Anne you don't happen to know the dulux colour most close in composition to Colorbond Dune so I know where to start? Thanks again and I would love to hear from anyone who has got a dune roof and hear if they tried light coloured gutters and what render colours they have used on their walls.

In my last house, after adding a living room (the area you see this side of the arch) and also updating bathroom etc I couldn't afford to reline the ancient walls in my little lounge (when I removed the purple wallpaper I found a mixmax of boards, gib, pinex, plywood and holes!) so I plastered walls all over with layers and layers of newspaper and wallpaper paste (papier mache), then after applying primer/undercoat I painted with 2 similar colours (rich reds in this case), and stippled the surface with a plastic bag. This made it look just very slightly textured like leather and successfully disguised the uneven surfaces. Gallons of gap filler filled the gaps between the old T&G ceiling boards and evened out the mismatched skirting and scotia. Again white paint on all the trims. Amazing what can be done when you have to make do! This was a great cosy little room! (Before photo is the 3rd one)

I found it here...but God knows how much it's worth... http://www.notey.com/@contemporist_unofficial/external/788254/volver-by-studio-14-for-terzani-raquo-contemporist.html

If you want to make the house hotter, then painting the roof charcoal will certainly achieve that. Repointing the brickwork is the most sensible from a maintenance perspective. Once you render and paint, then you have to keep painting (and it's likely to be out of fashion sooner or later). Try to keep passive cooling in mind (i.e. light colours & permeable landscaping) with any of your renovations, and I think it always pays to try and embrace and compliment the original architecture and be unique, rather than trying to look like the latest project home. In my opinion the arch window is actually quite cool, and the excellent mock-ups provided by Geo Toria are along the right track.
