Whale is right, just one thing to add re the process. From what you have said it would require Council approval. To put in a DA with the Council the owner has to seek approval from the OC with the Development Application, which would include all the specifications etc. Where the OC approves that, the common seal is then affixed to the DA so the Council knows that it has been through that stage.
So one suggestion is that the owner should be asked to submit their DA to the Owners Corporation for approval. If I were an owner I wouldn’t approve it unless that was provided, not least of all because the plans could change.
Luke – it isn’t a lot of work for the manager or the EC/OC, or it shouldn’t be. The onus is on the owner, they are the ones who want it, they have to do the work.
