As reported in the news ACTPLA accidentally approved three buildings on the Kingston foreshore to have five floors instead of four as dictated by the Territory plan. Interestingly a web search shows the ACT Government and the developers released a media release in December 2006 which clearly states “The blocks provide an opportunity to build up to four stories of office space with an option for residential on the top two levels.”

So in other words all the parties knew way in advance that there could only be four stories. So what happened? We won’t ever know because it’s all hidden deep in the files.
