This house is local to me and has been for sale for a very long time, pretty much since it was built. In fact I’m not sure if anyone does live there or if they have just staged it to look like they do.
It used to be a lovely road, full of quirky older houses, but there has been a trend recently of buying houses there for £1.5m ish, demolishing them and replacing with this sort of property, which they then try to resell for £3m plus.
It’s always been an expensive road, but is now a rat-run from the villages to the M42. There are much nicer areas locally where you can buy similarly priced properties in much more scenic and quieter locations. I have no idea why anyone would want to live along there, but properties - other than this one - do seem to sell (usually followed by a major renovation knocking the soul out of beautiful older houses).
