Prices round here have gone to the ridiculous, considering we paid £62,000 for our shed 19 years ago.
As you have said its pretty decent around here, but the great thing, as you have said is that central London is only 20 mins away by tube, but about 30 mins by car, if you are lucky, considering...
I live in a 1 bedroom house at the moment, which are going for £325,000 in today's market.
If I even had half a million pounds on tap, the wife and myself would jump at the chance to move back to Sussex in a shot :)
