When the government talks about infrastructure contributing to the economy   the focus is usually on roads, railways, broadband and energy. Housing is seldom   mentioned.Why is that? To some extent the housing sector must shoulder the blame. We   have not been good at communicating the real value that housing can contribute   to economic growth. Then there is the scale of the typical housing project. It   is hard to shove for attention among multibillion-pound infrastructure project,   so it is inevitable that the attention is focused elsewhere. But perhaps the   most significant reason is that the issue has always been so politically   charged.
Nevertheless, the affordable housing situation is desperate. Waiting lists   increase all the time and we are simply not building enough new homes.
The comprehensive spending review offers an opportunity for the government   to help rectify this. It needs to put historical prejudices to one side and take   some steps to address our urgent housing need.

Evidence   shows that 60,000 extra new homes could be built over the next five years if the   cap were lifted, increasing GDP by 0.6%.
 Ministers should also look at creating greater certainty in the rental   environment, which would have a significant impact on the ability of registered   providers to fund new developments from revenues.

The Labour party has recently announced   that it will retain a large part of the coalition’s spending plans if returns to   power. The housing sector needs to accept that we are very unlikely to ever   return to era of large-scale public grants. We need to adjust to this changing   climate.
