Hi chittering5 we used the 25.5cm lights. Our island bench is fairly small at approx 1800x900mm. I actually purchased 3 (at much better price than currently listed) but felt it was too many for the space when I mocked up the (widest) diameter of the lights with paper cut-outs. Trying to decide if I can use the 3rd light in the bathroom or something without it looking lonely....

Thank you everyone for all your help and advice! Yes, we live in an inland part of Southern Australia that is very chilly in winter and exceedingly hot in summer. So efficiency is a very important part of our build. From the picture you added Louise, I think a "coffered" ceiling looks like what I would call an "up lift". I'm glad to have a second on that option ;) The picture looked good, and could defiantly be an option over the dining table I think. Thanks jbantick I looked up "scissor trusses" and they look like a great idea as well. I'm just not sure how they would run. From the entry across the dining area (N to S) or across the whole length of the 3 zones E to W ? The middle of the roof line (running E to W) doesn't run in the middle of the living zones (if that make sense) as it stretches across a hall way on the south side. If it ran this way would it look a bit off centre? How did you in vision it? Thanks for your thoughts guys.

There are no strict rules here, but I do have an opinion (and I'm sure many fellow Houzzers will too)! I don't think you need to have the light fittings all match or purchase them from the same series, but I do find it feels nice when there are elements of the designs that compliment the others. This way you can choose the best lamp for the rooms without worrying too much about the other spaces. You can do this by selecting a colour, material or shape that you marry/echo in the next space. All the best, Sophie

Perhaps you could post some photos of your selections? I am having trouble visualising what a blue marble-look floor tile actually is? Could you use it as a splashback tile?
