What a fantastic architecture. When you do the brick, if you stain it with masonry /concrete stain you won't have the same issues of maintenance as with paint. They will spray it evenly - through you will have to select a deeper color - either taupe (brown-gray) or a straight charcoal. Love your windows and the classic angled railing. I think a dark gray on the siding will make the orange brick jump even more. What bothers me is the white (railing, fascia, eaves) juxtaposed with the earth toned stuff. So I would recommend camel tones - for the siding - something like http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW6108-latte/ and the hopsack next darker tone for the garage door. Use the lighter tan for trim that is now white - http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW6107-nomadic-desert/ Use the darkest tone if you are painting concrete steps. If you think you will stain your brick charcoal, then the white eaves and trim are probably right, and you may not want to paint it tan now and then go back. If your brick were charcoal, then I would block out the rest in grays and blue grays - leave the white eaves, but take the railing and posts charcoal too. A blue gray door - like sw smoky blue.

Start by making a list of what you would like the room to include: size, windows, flooring etc. Then find a trusted architect to do the plans.

Where is your house? Low maintenance plants depend on the zone. I wouldn't plant in your rock skirt. Ideally you'd put your rock skirt around the house and then planting beds outside of that. The skirt keeps mud and dirt off the house and let's you spray for bugs etc. since your skirt runs right up to the driveway on that side, I think your options for plants would be some large pots or window boxes. I'd paint your foundation the same color as your grout in the brick to help it blend in.

It's not showing in the Ozzie forum. You need to change your country to oz, then start a new thread, with the photos and post it. If you go to the Ozzie forum, you won't be able to find it. So what I think you have done, is just change your setting...but you need to post fresh I am afraid! So you will have two posts, one in NZ forum and one in oz...but the Ozzie peeps will only see your oz one, so don't mention posting previously Keep that between us. :)
