It's quite a while ago, mid nineties I think.
I had the opportunity to purchase a 5 acre field on the side of a main road less than two miles from the town centre for £25000.
I was chomping at the bit to build myself a nice house with enough space around it that I wouldn't be rubbing shoulders with my neighbours.
I called in at the planning office for a chat and a nice man came down to talk to me.
I laid out my plans and he asked me to hold on while he went back upstairs to check some stuff.
He reappeared shortly with a map, and said to me. " I can't tell you that your application won't be successful, you will have to make an official application and pay £x before I tell you that, but here is a map of that area, here is the development zone out to the bypass. Land on the other (my) side of the bypass is zoned greenbelt.
There are exceptions but unless you are planning this that or the other (which I wasn't) you won't get approval, but again let me emphasise I can't tell you that unless you make an official application and pay £x.
I thanked him and left.
As often in life strange things happen and a few years later the old farm house adjacent to the field came up for sale and I bought it. That is a whole story on it's own.
The farmer again approached me about buying the field. I declined, feeling reasonably happy that I would have no neighbours in the foreseeable.
