To combat the increasing cost of energy and reduce greenhouse gas emissions, increasing use is being made of timber frame building as an efficient, high quality and sustainable construction method. For example in the UK, timber frame construction is increasingly specified by housing associations seeking to develop affordable, high quality, energy efficient homes, with over 25% of all social housing projects being based on timber framed construction. Timber frame construction is increasingly seen as the modern alternative to traditional brick and concrete construction in many areas of the world.
