That's another problem.
I live in a Lib Dem area and vote for them. The campaign locally is to actually stop building on green belts and to protect the parks countryside and walkways. Make less strain on the hospitals and roads. Some terrace houses need to be torn down to widen roads near me, they're huge bottle necks.
UK has the smallest homes in Europe already. Quality of life is important. I think people need a bit of space. There's even a affluent area near me with big old detached homes, they squeezed in 5 homes last year on this patch of land amongst these large homes built in the 1930s and 1960s. Not only do they look odd, two out of the five have already moved out. There's no privacy or space compared to the homes from the 30s or 60s. You're paying 500k for a 150k new build experience. The novelty of a newly fitted home wears off soon.
3 years ago they did the same down my road. Left the original house in place, and built *twelve* homes where the garden used to be, then sold them at nearly £500k a pop when I had just bought mine for 300. Mental.
