It is time that the building industry embraced change. Good for the planet and good for their profits. And good for government building targets. Currently we are building about 150,000 houses a year. The new Government plan to raise that to 300,000 houses a year to help house the 3 million odd immigrants let into the country over the last few years by the previous government. Not to mention of course all the future ones they are planning to let in. Incidentally that equates, at an average housing density of ten an acre, to 30,000 acres of mostly agricultural land going under tarmac and concrete every year.  So, if Labour did meet its house building targets some 150,000 acres of land will be built on over the next five years.  An area slightly larger than the New Forest National Park which is 140,000 acres.    It is though easy to ‘talk the talk’ but can the government ‘walk the walk.’
