TIGHTER planning and building regulations are at the forefront of the Government's efforts to tackle global warming.
New homes must adhere to strict insulation standards and they must be packed closely together, both to economise on land and to encourage public transport use.
On some schemes, councils restrict the number of parking spaces to discourage car ownership. Moreover, a high proportion of new houses are built on brownfield sites, often reclaimed from industrial uses.
Such measures enjoy widespread support across the major political parties. Yet the negative environmental effects of these policies are substantial, and there are far more efficient ways of limiting carbon emissions. As the Government proposes to build three million homes by 2020, it is critical it looks again at its policies on how and where new houses are built.
Severe problems are caused by the locations that developers are being forced to build on. Many brownfield sites are particularly vulnerable to flooding as disastrously demonstrated in recent weeks.
Traditional industries clustered in flood plains to take advantage of flat land and easy access to canals and railways. Given the high costs, it seems unlikely that such locations would have been redeveloped without generous government grants and restrictions on building on more suitable greenfield sites.
Planning policies must therefore take part of the blame for the scale of the flood damage.
And there are other risks facing property owners. One new development near Leeds is squeezed in between a busy dual-carriageway and a railway line. It also sits underneath a run of electricity pylons. Unfortunately, such substandard sites are all too common thanks to current planning policies.
High density housing also has negative consequences. Small gaps between homes mean that nuisance from neighbours is more likely. Everyday annoyances such as screaming children, loud music and unpleasant cooking smells are far more intense when households live cheek by jowl.
While housing in other developed countries has been gradually improving over the last few decades, this has hardly been the case in the UK. Regulations mean that Britain's new homes are now the smallest in Western Europe. They are probably smaller now than they were in the 1930s when the country was only a quarter as rich.
It is also notable that the planners have severely limited the size of gardens in new developments. This doesn't seem sensible in the light of government exhortations that children should play more sport. In many new developments there simply isn't room for the games of footbal
