As Miss said, you can get all the documents relating to your property from the mortgage lender or the solicitors (think thats who i got mine from)
Mine is good, shows all the area around and the development in stages, not just for my road (cul-de-sac). Shows the proposed area, and then later after the houses and streets were built, all the changes they made!
Over the road is a layby, which on the plans shud have been a road into the next street, which was never built and ended up being a factory complex - not demolished and developed into houses, nursing home and store and car park!
Tells the conditions of trade that can occupy the ares, abatoirs, steel works etc!
Realy good info to find out about your local area, not just your house!!
