It's possible to live 5 minutes walk (or maybe 10-15 minutes) from Harvey Nicks without living in London. Just live in any of the apartments in and around Leeds city centre.
On this score, Leeds, and similarly Manchester and maybe Sheffield are pretty great places to live.
OK, we're a little far from the beach, but plenty of lovely beaches accessible for a day trip, but there's 2-3 airports within an hour or so, real wilderness and the Peak District, Pennines and Yorkshire Dales within about an hour, as many coffee shops as you could ever want and all the big shops like Harvey Nicks and John Lewis as well as loads of great bars and restaurants and a good number of local and national museums too.
