Hi Sara, I definitely agree with the other responses here; you cannot put Woodland Grey with Ironstone. If you like Woodland Grey choose warm green/brown colours to compliment such as, Surfmist, Dune, Pipe Clay. And for the fence consider going darker still such as Monument. Blackest Brown is also lovely but not as popular because, well, it's brown.

Timber Decking near pools does look great! We do get lots of enquiries for replacing rusted timber connectors in decking areas near pools (usually replacing with our Stainless Steel Timber Connectors), that's not to say don't do decking, just make sure its done right!

You've got a good space and good ideas. My suggestion would be to decide on all the structural changes first. It is tempting to go for small wins first. But you'll never regret doing a master plan. Set out everything you want to do. It's OK to have lots of stages and even a few dream things.

there are way too many colours going on here. Your home is a traditional style and yes the cream and green are traditional colours with the reddish brick however why did you put grey around the windows??also you have red scollops above the grey and it doesn't do the house justice. What colour was there before you painted the grey?? considering grey is a more modern colour I think you were attempting to modernise the externals. in saying that the roof would have been better to paint charcoal the cream in white and then the grey and then the driveway would be done in a grey stain. but if you leave it the way it is and cover the red scolloping above the windows the same grey and the bricks below the windows near the ground grey as well then get the drive way restained to the reddish colour of the bricks on the house and then it would blend more and look inviting.
