Documentary exploring the changing face of neighbours, illustrating both bad behaviour and some of the more objectionable properties to live next door to. Some of the less-than-neighbourly behaviour featured includes a resident who attacked his neighbour on YouTube and a homeowner who discovered their front lawn had been secretly purchased by their neighbours. The programme also illustrates some undesirable amenities to have on the doorstep, from a round-the-clock abattoir to the ghostly rumble of a night-time tube - and one homeowner who was shocked to see a block of flats being erected right at the bottom of their garden.
