Almost all buildings erected or altered in England and Wales must satisfy the requirements of the building regulations. This essential reference has been revised in line with new legislation up to January 2004, including important revisions to Parts B, E, H, J, L1, L2, and M and an outline of the proposed Part P. Each chapter explains in clear terms the appropriate regulation and any other legislation, before explaining the approved document. The Appeals and Determinations have been repositioned at the end of each chapter. Publications lists and relevant sources of information are also included, together with annexes devoted to legislation relevant to the construction industry, determinations made by the Secretary of State, and sample check lists. This highly illustrated and practical approach to the subject makes this the indispensable, one-stop reference guide for professionals and students.
