Browse Forums General Discussion 1 May 24, 2008 7:00 pm I have a old but very nice double brick house in woodville, south australia. I and my wife want to extension at our back yard. this extension probably is over 100 sqm. I got a quote from a builder. Shocking. It charge about 2000 dollars per sqm. In that money we can build a very nice new house.
so far, I don't know how to do next. I don't know why extension is so expensive comparing with new house. my extension do not need merge with our old house. Now I start to think whether i can build a new house in my backyard. Now question is, do i need subdivision my land? does builders want to do this? Thanks in advance Re: why extension is so expensive? 2May 25, 2008 8:59 pm its because its not standard, same reason building a home rather than building a estate base home, they design those things to reduce building wastage, know down to the hour how long each task will take so can have the next stage ready to go, use the same range of fittings and fixtures so get a discount.
ANd while you said it doesnt attack the old house still has some sort of roof magic to join, plumbing/wiring of the old house is unknown, it may not be square which means stuffing around. I did a major renovation but kept 3 of the 4 existing walls, almost all builders refused to quote the job only offering day rate and rough guides because its just to hard to work it out and they don't want to get left high and dry. Re: why extension is so expensive? 3Jun 05, 2008 2:11 pm Yeah having gone through two reno's there is always something you don't know before starting.
It could be the walls weren't built to code or termite damage that was never repaired, or the plumbing hasn't got the correct fall needed..... It goes on and on and most of these things can't know until you start knocking some holes in the wall. Re: why extension is so expensive? 4Jun 06, 2008 12:24 pm exactly alot is unknown when you do an extension, they would also be required to harness all the cabling and sewage from your existing house to connect it up (maybe even replace), which is more work than laying down it down for the first time on a new home.
Also If you sub divide you would need a new water and electrical metre for the extension dwelling and also a few other things So not to my knowledge you dont need to, but depending on which council area you are in they have different requirments (eg. the extention cant be bigger than a certain m2). Im a building surveyor myself. Sub divide also means that they are two total separate houses non related, which may mean you would require items such as a new rain water/detention tank for it and to be accessible from the road and not have to go thru your current house. That sucks! Hope it all works out. Good to move away from steel anyway for all your reasons, but it's also thermally poor. 16 18436 Hi All, I just wanted to close this topic out with an update.
