I plane to either add about 70 square metres to our house or build a granny flat style to the same size beside our existing home. It is brick veneer with tile roof on very slight gradient with good access.
Just wondering what would be the best option and if anyone has an up to date average value per sq mtr for building additions.Hi Burls,
The price depends on a whole range of things (for extension as well as granny flat). I often find that granny flat extensions are cheaper per sqr mtr. Things which effect price include:
– quality of finish
– site works
– single or second story extension
– speed of construction
– city– AND HEAPS MORE
I'm sure if you speak to a specialist in the area you are looking to build they can give you a ball park figure. Also, here is an article to give you a really rough guide (about the extension):

The per square metre price of a granny flat will be higher than the per square metre price for a four bedroom house. You could either get a project builder to build your granny flat (there are plently of companies I know of in Sydney who can build you a kit home granny flat) or you could get a draftsperson to do up the plans and then get a few quotes from different builders to build it. I would say it would cost between $80k and $100k to build a 60m2, two bedroom granny flat including services connection, drafting of plans and council fees.
Cheers,
LukeSorry forgot to add, are you in NSW? Getting approval for granny flats is easy here but they can only be 60m2 maximum. I am not sure about other states but check with your council.

80 to 100k? You can get basic home from mastertons for that much. Keep shopping around. There is cheaper then that.
I wouldn’t pay nothing less for basic lightings and fixtures at around 65 to 85k.Check out the different buidling materials that are out there. The kit homes are also rip offs. And can be more costly in the future for constant repairs.
This is very interesting, I am thinking about the same thing. Lets see, I want to turn an existing garage into a granny flat.
So the external structure is already there. I just have to fit out the internal.
What do i have to consider?? Things that come off the top of my head are
– small sink, kitchenette
– Toilet shower and vanitiy,
– Electricity
– insulation
– Flooring
– Window dressing for privacy
What else have I missed?Also, What are the rules in regarding to leasing, with the council, the agent, (this garage behind a house i have in brisbane). Do i have to have a development approval?
What else have i missed?Correct me if I’m wrong, but I think once the kitchen and bathroom are put in, it is then declared a dwelling and probably need DA approval.
You do not necessarily need a DA for a granny flat. Under the new housing affordability scheme most granny flats can be built/approved under a complying development. A DA is only needed under special circumstances- just drop in to your local council and have a chat with the town planer, they are usually pretty helpful.
cheers,
LukeYeah I wish wingercaribbee council was that easy going
Best to drive around the local area where you plan to build or look for similar dwellings. Find the builder that has recently completed a house/granny flat. Speak to a couple of builders and they will be able to give you accurate estimates.
