I do find the massive distrust of architects on here a bit odd, like any profession there will be good and bad ones.
some of it is expectation - you can't expect a custom build to be the same price as a project home builder, however 99% of the buying public have no clue and they are all that matter (unless it's purely a build for yourself)
having said that some of these architects do do stupid things - like that one in Leederville I had the misfortune of being in - circular central steel stair case. could not be fabricated in WA, had to be sent from over east. there's money you can kiss good bye
