No black and white? Then there's no proof MPAJ allows it. Don't fall to this trap.

Also rebuilding on your part may means different than rebuilding on the MPAJ part. Tearing down the whole structure and build a new building is not rebuilding I believe, but instead a new construction. Tear one part down, leave some part, rebuild the teared down part.

And of course, this varies from council to council. Best you engage your local tradesman, on the legal way and the illegal way.
