Ah but cloudpants what are you making it real in comparison with? Who's to say that not painting them wouldn't look far better? Before you say anything....I made no comment either way...and yes it does look really good!

I think a nice grey (not too dark, but darker than your concrete driveway colour), on the weather boards OR the render around the entry (not both) would look great! It would modernise your home further; bring out the brick more; and tie in with your driveway and roof? Green foliage also looks great against grey so will complement nicely when you get your garden established. I can't reccomend any particular grey as I know nothing about paint colours, sorry!

With such a large house I think it would need some other darker colour along with white to help "ground" the look. Also, as mentioned above, pure white on an exterior looks very glarey - surfmist would be perfect. I would strongly suggest getting a colour consultant to help with such a large project - and get some mock-ups done with different colour ideas.

I love your bricks too. In fact I would repaint trim colours the same as they are.
