I own an apartment where the balcony is not on the title. It was built on a common property by a builder without a permit. I am in the process to get council + surveyor approval to have this balcony "legalised". Also, I have approval form all owners of the apartments in the building and body corporate to include this balcony on my title or have 99-year lease. My question is which option is better and cheaper to execute, taking to account I will seal the apartment in the near future when all is finalised?
