You should be able to do three panels in those windows up into that arch with horizontal louvers and fully functional. Your shutter maker just needs to line vertical posts up where you have vertical mullions! giving that center shutter something to hinge to. Here are a couple of similar windows I have done. It's a partial arch but it's the same concept with yours

Hi Annb1997 I was also confused and intrigued about the two sided binds - so looked them up and found they differ from double rollers. A company called 'Blinds on the Net' supply them. They are called Zebra Blinds and this extract from their website explains how the operate "The cleverly designed Zebra Blind utilses a horizontal striped fabric with alternating Translucent or Block Out and Sheer stripes. Two layers of this fabric move independantly to create overlaping combinations or Translucent and Sheer or Block Out and Sheer. A simple but effective idea that allows high levels of light and privacy control with the one product."

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.

Hi Gwen, I would keep the shutters facing the front of the house looking the same. It would look weird if there was one window at the front that had a different coloured window.
