A bit of a dramatic post.

Were you aware that 93% of the UK is urban, that means not built on by houses, factories roads etc.

So you should be able to find a green field, there is a lot of them about.

And at what point will enough be enough?
When will roads be too gridlocked, hospitals too full,food water and electricity in too short supply,too few jobs and the countryside too eroded?

It seems your philosophy has no limits on population growth.

We have the lowest productivity levels in Europe.
One of the reasons for poor productivity levels in the UK is the poor infrastructure. Succesive governments have welcomed immigration without any plans to deal with the everyday needs of the population. Short term planning has gone on for decades and we are now paying the price. Blaming the immigrants is only a get out. A long term plan must be made to improve housing, education,health and infrastructure which would benefit the whole population. Admittedly hard to implement but would show that our representatives are working for the good of everyone and not just the City of London

Go on, edumacate me. What percentage of the uk is geologically not suitable for building on? Geological and geographical if you could seperate it. I'd look it up myself, but apparently I'm 'thick'.
What percentage of potential building sites has no farmland or national park.

Well Einstein, the thing is that the countries infrastructure would be in meltdown decades before we ever built on all the available land.
Have you not noticed that our roads, hospitals, prisons and electricity supply are already under strain.
