Michael Ankers, chief executive, said: "Whilst overall we welcome the green paper, we are disappointed that it does not address the problems of existing housing.  Based on current building and demolition rates around 70 percent of current housing will still be in use in 2050.  This existing stock is the most energy and water inefficient, with far too many properties not of a 'decent' standard.  It is important that the government addresses the standards for existing stock alongside those for new houses. 
 
"The problems that arise from insufficient housing supply are all too evident and there is no short term fix, as was illustrated in the Barker report.  We are particularly pleased to see a sharp increase in social and affordable housing.  This is not just a problem for public sector employees but is also a concern for many private sector employers throughout the country."
