You can get well proportioned new builds that are on nice plots, you just pay a lot more for them. Its a reasonably simple calculation I imagine. If they can fit 10 £250k houses on a plot or 5 larger houses, those larger houses will be roughly twice the cost. There is more demand for lower priced houses and they probably get some sort of kickback from the government for building them.
Unfortunately the government allows all these massive companies to build absolute crap houses and get away with it so the quality is often appalling.
