Looking for a little help with this. Over the last few years I have been doing a few granny flats in NSW which have worked out well. Now looking at other markets to do similar developments. I have my eye on Brisbane at the moment. I know renting out granny flats is not allowed in Brissy so im investigating buying a good sized block (600m2+) close as possible to the city and plonking another house on the same lot. What is the minimum lot size to do something like this? It would be good to be able to subdivide later but from what I understand you need a block over 800m2 to make this possible in Brissy no?
