In our enthusiasm and drive to move closer to energy efficient and air tight housing, let us not forget that we also need to remove the chemical threat from our living environment. It is time to move over or rather move back to natural building materials and to look at how we decorate our homes. It is a personal challenge that any private individual can undertake. The solutions are out there, but until regulations are in place will large developers really change the products they put into their housing estates or flats?
