Thank you everyone for all your help and advice! Yes, we live in an inland part of Southern Australia that is very chilly in winter and exceedingly hot in summer. So efficiency is a very important part of our build. From the picture you added Louise, I think a "coffered" ceiling looks like what I would call an "up lift". I'm glad to have a second on that option ;) The picture looked good, and could defiantly be an option over the dining table I think. Thanks jbantick I looked up "scissor trusses" and they look like a great idea as well. I'm just not sure how they would run. From the entry across the dining area (N to S) or across the whole length of the 3 zones E to W ? The middle of the roof line (running E to W) doesn't run in the middle of the living zones (if that make sense) as it stretches across a hall way on the south side. If it ran this way would it look a bit off centre? How did you in vision it? Thanks for your thoughts guys.

Hi I was over in Brisbane a few weeks ago looking at some homes to renovate recently and while doing some research came across a concrete home built in Newfarm a while back. If you search for an address in google being "concrete home gibbon st" you will find an article about it and the architects details. He was Larry Weston from memory....not sure what his practice name was... Only comment would be that both the engineering and finishing of exposed surfaces need to be done by people with experience. You will pay extra for this type of detail but it is worth it to avoid an unsightly crack right through your feature wall/floors. Good Luck.

Hello houzz helpers! We have a rough new plan! The kitchen, living, dining are on the north and bedrooms are on the south. We are planning to push the house to the rear (south) of our 1 acre block and have a long driveway. We can look out onto our beautiful (in time) front yard and watch the kids run wild! We plan on using landscaping along a front fence for privacy. I am concerned with the size, in regards to being way over budget, but I am hoping the simple shape of the roof will help to offset some of that. I was thinking I would get the plan as close to what we want/need then get quotes and scale back if we need to, which will involve another post on houzz ofcourse! We would love your honest feedback and I am happy to answer any questions...

Thanks for the advice team. So the house is block work on a cement slab, but when we did our renovating in the bathroom and had to cut through and re-lay the floor in the very small bathroom we noticed that the slab was incredibly thin and had no reinforcing. The walls have some cracks however we did have the building inspected when we bought it and thought we had a solid shell to start with. (Its brick and cement we said - what can go wrong?!) Our house is not in the flood zone. There is an asbestos ceiling which has also complicated matters a little - everyone who has quoted on the job has vowed not to disturb it - but I am not sure when you are walking around up there and pulling the original roof off if this is actually possible. The roof is a flat cliplock roof with no crawl space at all, so the ceiling is on battens that are attached to the rafters. The block of land is 822 sqm and will be worth about $130 000 if the house was demolished. (Demolition is set to cost around $30 000- due to asbestos etc) We have spoken to an architect who has told us that it may be possible to reuse our kitchen, the solar set up and some windows, but if we try to force the project to reuse all of our windows and doors it could end up being counter productive. So if it happens to fit we might reuse. I just spoke to a real estate who are telling me that in our area a small new house (3 bedroom) will not reach the $300 000 value point - so it may be impossible to reach the right formula to allow the bank to lend for a rebuild-
