and all has told me to say between $10,000 and $14,000.
maz I think J means $10000 - $14000 a square, not a sq/m (a square is approx 9sq/m) so thats approx. $1100-$1550 per sq/m. Which is a good ballpark figure for a fairly standard to slightly more complicated house. And I feel the house Fionas PM Mel is a little above this figure

Depends really on size, the smaller the house the bigger the cost per square metre he says.
yep I would agree, but when buildings get complicated this gets a bit different. No offence to builders, but when things start to get a little different/unique/complex the cost goes up, up and up. Granted a more complex building will take more time, but I think some try to squeeze more $.
