In my immediate neighbourhood, there is a house which is set way, way back from the others, on a road which is basically a one-sided, long cul-de-sac, adjacent to a main road (I know it sounds confusing). It seems bigger and grander than it's neighbours.
I've never seen anyone come or go from there when I've gone past, but lights are on sometimes. I sometimes wonder why the house was built there, and who lives there. I like to imagine an eccentric old aristocrat living reclusively. Is there a house or building in your area that you are curious about?
