To clarify the practical requirements of the Building Regs and help you meet their requirements first go, all the information contained in the building regulations 2010 and approved documents is presented here in an easy-to-understand format, clear, concise and fully illustrated.
Guidance is given for domestic buildings of up to three storeys in England and Wales, including extensions, loft conversions, new dwellings, conversions (garages, basements and barns), and upgrading of existing buildings - including the use of natural lime mortars, plasters renders and paints. There are clear explanations of how the technical design and construction requirements of the Building Regs can be met with sufficient information to draw up an effective specification and design to be developed.
Guide to Building Control illustrates the design and construction of the various building elements and explains the principles and processes of the building regulations and approved documents - including structure, fire safety, contaminates, sound insulation, ventilation, water efficiency, drainage systems, combustion appliances, stairs and guarding, energy conservation/green building issues, disabled access, safety glazing, electrical safety, materials and workmanship.
The Guide contains up-to-date examples of everyday practices and procedures gained by the author - a practicing building control surveyor - from years of responding to requests from property professionals, builders, property owners and students for clarification of the practical requirements of the building regulations.
Accompanied by detailed diagrams, tables and text offering an enlightened understanding of the complexities of building regulations the Guide is both an authoritative reference for use at planning stage and a practical handbook on site. Students and professionals will find it an essential, easy-to-use resource for building control surveyors, building designers, building contractors, self-build, and others working in the construction industry.

Anthony Gwynne, MRICS, MIFireE, is a Chartered Surveyor and Fire Engineer and has 35 years' experience in the construction industry. He co-manages a building control section and has been in building control for over 19 years. He has been responsible for overseeing the building control function of major developments, including commercial, industrial, healthcare, residential, housing developments, bespoke dwellings, extensions, conversions and works to heritage buildings. From 1976 to 1977 he worked in Canada on construction projects and from 1977 to 1986 he was apprenticed as a banker mason and was responsible for conservation projects with CADW (Welsh historic monuments and buildings). Following further academic study, he was later with English Heritage as a professional and technical officer, responsible for historic monuments in the south of England. From 1986 to 1993 he was a Building Surveyor with a local authority, dealing with the repair and planned maintenance of buildings including contract procurement and contract administration.
