Thanks for your reply. Not sure which wall you are referring to? We can't block the bedroom that is next to the front door and we don't want people walking directly into the lounge. We also want the deck to be private. Do you mean to have the gate and doorbell outside in the open?

Thanks for the replies! My wife suggested we talk to a local real estate agent, so i think that is a good idea... just that Im not sure how helpful they are likely to be if we arent selling yet :) As for saving for our dream house, I dont disagree, however if doing this up nicely over the next ~5 years or so while we live here nets us some extra in the eventual sale, then that of course will help us as well. Interesting thing happened today actually. I got a knock on the door and one of the older neighbours asked if he could take some lemons from the tree. I of course said yes. Anyway he was telling me he had lived in the street for 40 years. I asked him if the house had always looked like this, and he said no that ~30 years ago the old old owner did a massive renovation and pulled off the timber and put up the bricks and gutted the inside of the house. Interesting stuff!

For external doors most definitely yes! Copper has unique characteristics and is beautiful, like anything it depends on where you apply it.

Thanks very much for all your feedback. Just to answer a few queries - the deck is directly outside the main room so the new doors open out onto it. The doors won't be French - they're just the only doors that the 3D planner I'm using had, they'll actually be large stacking doors. I've had another idea too which would be a lot more expensive but offers a completely different approach. This is quite rushed so doesn't show accurate layout of kitchen or anything like that, basically just provides an idea. Thoughts!?
