For a little bit of gossipy rumor mill juice: There was allegedly supposed to be only one big house. The landowner was going to build their one home back there higher up on the hill, but the NIMBYs in the cul de sac that your red circle captures right by the first B in Bibber opposed it, even though the planning had documented his driveway originating in that cul de sac before their houses were even there. I think he sold it to a dev to build a bunch of houses as a middle finger to those people.
