I wasn't talking about the bit near the river. The areas of "Battersea", "Wandsworth" and "Clapham" are often misunderstood.
There is a large area called "between the commons" - a huge residential block that sits between Clapham Common to the West (which is in Wandsworth) and Wandsworth Common.
Much nearer to Balham in reality.
Running up the middle is Northcote Road.
You should see Gordon Ramsey's place.
One of the reasons for the house prices is that it's quite usual for central London. Very central, residential, arguably the best transport links in London and very "green" with a park and two commons to choose from.
If living off Wandsworth Common isn't "upmarket" I'm not sure what is.
Technically just outside the border of "Battersea" there is the "toast rack" where a number of celebs live.
Do black cabs now go south of the river?
