There have to be controls on where we build or the developers would tear up all the countryside and we would never get it back. Not that it is all natural as unbuilt land is likely to be mostly farms (with a few golf courses). We should develop old industrial sites and accept that not everyone will be able to have a house. Some will make do with flats, but those need to be decently built.

I just looked it up and population growth is speeding up a little. We also need to replace a lot of old housing and make it much more efficient.

I can't imaging this sort of thing will change quickly as it all gets planned many years ahead and you can't magically find thousands of extra builders. Of course we could allow in lots of foreigners to do it! I do wonder about how their countries of origin do for key workers if we keep pinching them.
