As the London housing supply problem continues and lower income households are forced to move out of the city (city rents and cost of living becomming unaffordable), they may well encounter groups of economic immigrants entering Britain who want to live as close as possible to their prospective employers of the future i.e. at the city margins.
The pressure to house both groups is firstly an issue of the land. And secondly an issue of housing on that land. Both groups will want cheap land. And housing that can be rapidly and cheaply constructed (perhaps 3D printed or prefabricated dwellings).
Where might the cheap land come from that is relatively near the centres of thriving commerce in the UK? Typically, from land being sold at a discount, because of its drawbacks. Example include; ex-landfill land, land next to railway sidings or motorways, land next to busy airports, ex-quarries, land at flood risk and ex-industrial land. Councils, NHS Trusts and other organisations under financial pressure may also be interested in selling off surplus land, simply to help balance their books.
Since existing towns and villages won’t have the space (or the interest from existing residents in building new schools, shops, social and medical facilities for the new settlers), it’s likely that new towns and villages will need be constructed. Perhaps as high density settlements, Soweto style.
Central government would be wise to prohibit the construction of new towns and villages alongside existing airports, rail and road links. Why? Because this would prevent their future width-expansion, to cope with an increased settler commuter-traffic, to and from the main centres of employment.
Central government and the UK Environmental Agency would also be wise to prohibit the construction of new towns and villages on known floodplains, or in low lying areas next to the sea, for obvious reasons.
