I would try the Woodcliff Lake, it has a warmer tone than the lighter greys.

This just popped up , but I see it is quite old . Did you decide on paint colours ? The roof looks almost a brown tone in the photos , but you say it is dark grey . I assume you don't want to paint that ? If you do , go more charcoal IMO . If you don't , I'm assumimg it will look several shades darker with your wall colour choices . There is a roller door on the garage that appears to be a nice shade of orangey yellow . Personally , I would go with your colour choices , but do all the doors ( roller doors , wooden doors ) and gutterings in that ochre shade . Your terrace I would do in a charcoal , but with the top rail either in the orangey yellow , or a really crisp white . I know that sounds a bit 70's ( although they would have added a lot of ranch brown back then haha ! ) but against the light grey I suspect it would work together well , and look the part .

Thanks for that AJ Interiors. Yes we have painted chimney breast (white- same as walls) We have a bought a huge dark grey mirror (metal) which has a slightly industrial feel but also in a traditional French style shape (I'm not describing this very well!) the two combinations will hopefully work well in a tradition villa, giving it a modern look. But we really need an injection of colour to lift everything. Am looking for some copper/metallic bedside lights. Quite like this copper lamp from Citta . https://www.cittadesign.com/home/living-room/lamps-light-shades/guarida-table-lamp-wmetal-shade-IIE0005

Hi Michelle - It looks like treated pine to me, and looks as though it has been recently built. If you did nothing it would fade to a grey colour within 6 months or so. This would probably blend in with the house quite well, and you wouldn't have to do a thing! Otherwise I would stain it - there are lots of stains on the market - see if there is one you like. A dark one would create a nice contrast with the house and make the fence look more like a feature. Good luck!
