Brilliant Bobad! One of the very reasons I posted this question here. Ta for the link. Looks like exactly what he needs to get some more grounded ideas together.

As to more in depth questions. Nothing's settled yet. Today was just a scouting mission, which inspired a lot of unresolved pondering.
Hence the "what would you do" with a hypothetical acre question. (Whatever bit of land he eventually plumps for however, it *won't* have planning permission.)
