Northcote Road is a shopping street In Battersea, south London, which stretches over half a mile. It is close to Clapham Junction station. It is the epicentre of the so-called 'Nappy Valley', named because of the young, affluent and productive demographic and also because the road lies over a culverted stream giving it a low-lying position between the two commons of Wandsworth and Clapham.
