What did you show on the existing drawings - as approved, or as currently exists? I've never found out the exact rule/requirements in these instances.
Some local authorities seem to accept as approved as the existing, but some require the works to have materially started or be completed to do so. I think the issue some LPA's have with this approach is you never actually satisfy having completed the first scheme if you build in one operation.
Therefore some LPAs require the existing drawings to be as it currently stands, and then the second application would effectively be for the whole scheme.
