Here’s a paradox. In some parts of the country like Wokingham there is too much private sector investment going into new homes. The planning system decides that the homes should be built in these places, and then people from all over the UK and from abroad acquire them. Meanwhile in other parts of the country they are crying out for more investment and have very few new homes being built. These places often lose people who migrate elsewhere to set up businesses or to find better jobs and new homes. As the government wishes to level up and believes in planning it needs to change the planning system to allow places under too much development pressure to have less and places wanting more investment to have more. There is no iron law of geography or business development which says so much of the new housing and then so much of the consequential extra employment has to take place in a limited number of locations.
The imbalance in rates of development increases the cost of providing infrastructure and public services. In places with falling or slowly rising populations there is often excess capacity . Public services may need to think of closing surgeries or schools as the users reduce. The private sector may well have excess capacity in its water pipes, broadband links, electricity cables and the rest. In the fast growing areas many of these facilities need expanding and upgrading to cate for all the extra people.
