Tough ask to get the no visible fixings. Magnesium oxide board (see the INEX brand) would give you the light coloured look, sheet or boarded look. The product can be painted but looks great raw too, has a shiny side and a striated side so you can have a variety of looks. Good luck

The house is fairly small from the photo but elevated on a basement or garage plinth. If the base is brick, leave it as is. But whatever colour you chose, eliminate contrasts so if, say, a soft French grey, paint the walls, window and door joinery and roof flashing the same colour. A contract could be the new deck rail, but I would even consider painting it the same colour as the basement to link the 2 levels or just the same as the top. A bright glossy front door could break up the monotone.

Hi, firstly congratulations on your decision to renovate. How exciting. We are nearing the end of a major renovation and choosing the exterior colours was a real sticking point. Most of the houses around us were built in the 1990's and my renovation had the potential to not quite fit in. I had to use a timber cladding to match the existing cedar but the original had been poorly stained and I was never going to get a cohesive match between old and new. I was left pondering my choices. The solution was to paint both but what colour? In the end, I looked at what of the existing was going to be left unchanged. It turned out to be the Karaka Green window frames - not my favourite colour - but in order to work with it I had to pray I didn't offend the neighbourhood. I didn't want the old dirty brown shade and a thousand testpots later, left me with only one really obvious answer. As you can see from the photo, I chose [quite radically] to paint the entire extention in Half Karaka green. It's still a work in progress and in the coming weeks, the rest of the house will be painted to match. I waited for the neighbours - particularly, the old people from the Rest Home at the end of the street - to tell me off for my choice but have been blown away by their reactions. Every last comment has been a major thumbs up. Even the painter - who was highly skeptical - apologised for his doubt, Don't automatically assume your neighbours are going to hate seeing the changes you are about to bring to the area. Which brings me to your planned renovations. I am assuming that your window frames are also going to remain the white colour in the photo. Rather than get all confused about greys etc. Start with them as the basis for the rest of the house and work out from there. If you do that, then I don't think it will be as difficult as it currently seems for you to pick what the rest of the house will be. Don't be afraid to spend money on purchasing test pots. They are around $4 or $5 each and I believe that I probably spent $200. It was worth every penny to me to get a few small off cuts of cedar painted and sit and look at them alongside the existing windows in order to make an informed decision. Good luck. I look forward to seeing some finished photos. I hope to post my finished renovation photos here soon.
