Architectural practice has become considerably more complex in the last twenty years, not to mention since the days of Wright. Many more professions are involved in realising a building, and the construction industry has become professionalised in areas such as health and safety, management training and continuing professional development. Procurement methods for buildings are proliferating and roles for all involved changing, especially for the architect. Shorter timescales are common and there is a general consensus that, in the UK at least, there is a serious skills shortage in the industry and a decline in the quality of the building trades. The industry has become both more litigious and more international.
