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.

Wow love some of those pics Siriuskey! Thank you for the ideas. I struggle with whether to keep walkways 'clear' in this house - for example the two doors either side of kitchen and the deck door all create these weird walkways. (See arrows on drawings) Is it a smart move to 'block' them with say a couch, or an island bench, or the dining table? (See random furniture placement in pictures showing these options) I have uploaded a drawing with the current walls that we propose removing in green highlighter and showing where the current front door is. As you can see it's a wasted space and strange detour past laundry toilet and storage! I have sketched what I think you mean by entry next to bed 3- would you leave a small office room to one side and create a hallway or leave open and place miners lounge against west wall. Am I interpreting it all as you imagined?!

Thanks for your insight, yes I'd looked at Surfmist as well, clients seem quite pro grey so trying to subtly work their likes into the scheme as well, as I think they woule like a grey house however I think the monochrome black / white is classic and will endure the test of time longer than some shades of grey, also if they were opting for white windows may be more inclined to look at grey for the house colour however feel that the black windows will work nicer with the lexicon and tie in the black elements. Welcome all feedback

Yes, siriuskey. You are right again. It would be smart to invest in having a professional draftsman draw it up. But on face value, I really think oklouise's plan works. I have sort of drawn it out on the floor. I love that she is using standard size vanities with only a custom made top, and the towel shelves are now 450 instead of 250 wide, which is much better. The little odd-shaped infill at the end of the bath provides a spot for the lovely jug and bowl set my mother made for me. (I used to use the jug to pour water over the grandchildren's heads when I washed their hair, and now it's just a lovely decorative item with deep sentimental value) and there is space beside the bath for the urn filled with decorative soaps that was a gift from a son-in-law on his first visit to our home. I really think the bath needs to come back to 1500 long, but that's not an issue at all. I found a really nice shaped oval tub at 1500 x 760 that I like and is quite inexpensive. I don't need to worry about towel rails because I have a lovely timber free-standing towel rack that will fit nicely at the end of the shower if the shower door is placed on the side. It looks like the vanity drain can run under the drawers and into the bath outlet and the WC vanity will run under the wall into the shower drain, and all other plumbing stays the same except I'll ask the plumber to chase the shower tap and rose into the exterior wall rather than have it on the side, OR there is room for a false wall in front of the exterior wall to hide the plumbing if that works out better. The niche can go in the new wall behind the WC vanity. I'll be really surprised if this isn't a feasible plan, but I will take your advice, siriuskey, and get a pro to draw it up so I can be totally confident it works. Can't thank you enough, oklouise - and you, siriuskey, for all your efforts which, I think, contributed by generating new ideas and flushing out the important issues.
