Around 4 years ago my wife and I purchased a home advertised as a 3 bedroom with possibility of a 4th smaller bedroom\study. We conducted building and pest without issue and all was signed off and we were happy to proceed with purchase. 4 years on while going through the motions of an appraisal, an agent mentioned he didn't think the 2 rooms (previous sleepout\sunrooms) were of legal height for Brisbane. I've measured these and in fact they are 2.31 cm (9cms below legal height for a habitable room). This was either known by sellers and agent and undisclosed, or not and missed by the building inspection either way. Any ideas what type of legal discourse I could have here? A few agents since have suggested I could take action against the original agent, but that may be palmed off to the owners who signed the contract, while others have suggested that I take action against the building inspector. In both cases it has been suggested that we could look for compensation around the loss of property value over such? Personally I wonder whether it's just easier to look at how we raise the ceiling height if possible (gabled roof on outside implies we could lean the roof and acheve 70 percent legal height which gets the tick ) and not worry about the stress of taking action?
