An extra 15,000 houses in an area that currently only has 86,000 houses seems an extraordinarily high number. The population of Solihull is around 207,000 people, compared to a national population of 64.1 million people. The Government's target is to build 1,000,000 new homes by 2020 (i.e. over its 5 year tenure). For the sake of argument, Solihull should be looking to build 0.32% of these houses based on its population, which is 3,229 houses over a 5 year period, which is only 9,687 over a 15 year period. Therefore, there is no justification to aim to build over 15,000 more houses at the expense of the quality of the surrounding area.
