well they said it would cost us about 3 grand to render our whole house.. it isnt a massive house.

we got a bath tub installed recently and it alone cost 3 thousand, luckily they didnt have to rip up tiles from the ground cause that would have made it more.

we have an extension going up at the moment and it is about 20m2 or a bit more, no plumbing and its 40 grand. that was the cheapest quote another one was 60 grand.

i suggest you get at least 3 quotes from different people to make sure you get a good price.

carpets, mid range are about 36 bucks a square metre installed (and its not that great carpet) and tiles are quoted as $35m3 and instillation is at $30m2.

hope that helps.
