Here's an interesting one..... We are planning an extension to our existing home. It is 11.4 sq (106.3 m2) and the extension will add 12.4 sq (122.8 m2) to the house with a 53m2 multi level deck off the back. The existing house was built in 1966 and has monier 100 cement tiles on it. I had thought about doing the new bit in the same tiles to match up with the existing. This would mean a revamp of the old roof (pressure clean and paint, we already had the repointing done, as it was leaking)....
