The most environmentally friendly places to live are surely terraces or flats where you share walls and therefore heat with your neighbours.
Forty-odd years of living in a terraced house and listening to my neighbours' radio/TV/arguments/bedsprings (and they to mine) have convinced me that detached is best! Not much shared heat, either; the exceedingly long downstairs hallway was always like Siberia because of the idiotic way the place was built. This more modern, well insulated little bungalow with its neat, square hall is much easier to keep warm.
I do agree that rural developments just plonked in the middle of nowhere with no facilities and services close by are barmy and you couldn't ever pay me enough to make me live in such a location. But how many other places are there where people thought they were future-proof with shops and doctors, dentists, schools, pubs and bus services only to find those facilities gradually closing down and being withdrawn? Many once-thriving villages are now rural prisons with non-drivers virtually trapped at home and yet the planning rules allow ever more of these soulless developments to mushroom around us. Madness!
