It is considered the contribution that Solihull is making to the Housing Market Area needs is very modest. At 2000 dwellings this contribution to needs (which is almost exclusively generated by a shortfall in Birmingham, represents some 5.4% of the total shortfall. For Birmingham based households unable to secure housing within the City the natural choice of search will embrace Solihull, and unless provision is increased to accommodate a more realistic proportion, will result in a distortion to the housing market and a degrading of the preferred sustainable pattern of development as Birmingham migrants will occupy dwellings as close as to their work and social connections and exacerbating a ripple effect. The latter will be detrimental to a sustainable pattern of development. Within this context a share of the unmet need should be proportionate to the actual working of the housing market. A figure of 20% of the unmet need (say 7500) should be accommodated in Solihull, with the remainder being accommodated in the other 4 non Black Country authorities adjoining. This points to an increase in housing provision of some 5500 above that set out in Policy P5.
