Hi guys, Looking for a help with some information on granny flat size limit. We are planning to build a new single story home with an attached granny flat in NSW. The size of the lot is 451 sqm. The frontage is 15 mtrs. I was under the impression that any lot size above 450 sqm allows a 60sqm granny flat. I have been advised by one of the project home builder that we can build only 45sqm GF on our lot. According to them, lot size of 450sqm to 600sqm in NSW can only have 45sqm GF. Can anybody throw any light on this? thanks in advance.
