Hello- we are currently in the same situation. We need to pick out our new siding and Misty Shadow by Mastic is our favorite color, but so hard to find pictures. Did you end up going with this siding? Or did you find some good pictures? Thank you!

The space under the house doesn't look to be that accessible, so I would block it in as Johnathan suggests, just leave an access hatch for inspection and clad in stone to match the existing stone work. For the exterior I would continue the cladding using a composite like fibrous cement or UPVC with good insulation underneath and finish in a dark colour. The steel poles appear to be supporting the ends of RSJs so they will need to stay, just paint and maintain them as they are holding up their end of the house.

I like the last picture as everything matches, which is one of my concerns, as I definitely don’t want a white front door and I can’t change my white windows and garage door. Maybe I’ll match the front door with whatever cladding colour I go with!

Thanks @cushioncover - ours is one of two houses that are similar but not identical. We have three floors and our neighbours have two. They have recently had their reddy-brown wood cladding replaced with white uPVC. We would like something that looks a bit more natural e.g. plank effect fibre cement. The other houses on the estate are different and are mainly brown tones. I like the grey look as posted by @Victoria and have crudely photoshopped what this could look like if we were to clad the top half and paint the bricks at the bottom. Also sketched in a new drive! You'll notice I've broken my own rule and made the windows dark grey! This is because we've discovered you can have uPVC windows coated and that it bonds with the plastic, just like it would when making grey uPVC windows in the factory. So we're considering this. We have a garden room which is clad in cedar (similar colour to the photoshopped garage doors below) so it would be nice if they could tie in, but I don't want to clad in real cedar at the top of the house because I think it could end up looking a bit shabby due to the sun/rain? Has anyone seen fibre cement that looks like realistic cedar? I'd be interested in any thoughts in the below design? Thanks again :)
