With six different Berkshire councils and numerous appeals being handled by each, you would need to provide a little more to go on. That said, decisions like this are taken from time to time, apparently against the normal ‘no building outside the settlement boundary’ dogma. But invariably each case is different, and planning decisions are supposed to be made on their merits, not on precedent. So a stray positive decision might provide encouragement to chance your arm with an appeal, but it doesn’t set a new benchmark against which other cases must be judged.
