From that I would derive it's a multistorey building with 600m2  floorspace on a 533.0m2 section

Floor area over foundation and Land area should be very different things.

Land area should be the area of the section 

Floor area is typically related to the house plan being shown. If you are looking at a house plan with a floor area greater than your land area I am going to say this is most likely a mistake.

Hard to be sure without actually seeing what you area referring too.

I have re-checked the web site and it's definitely not a 2-storey house.

Had a look around at similar properties it is obviously a mistake on their part.

Thank you to all.
