House extensions and improvements have gained enormously in popularity as a way of providing more space and enhanced living conditions without the substantial cost of moving house. While there are many books that deal with the construction aspects of extending a house, there are few sources that combine the planning, construction and regulatory aspects into one easily accessible source. <i>Extending and Improving a Home</i> meets that need. By focussing on specific building elements – foundations, walls, roofs, services, finishes etc – the book neatly provides a comprehensive, accessible guide to the areas of home improvement that cause most concern for householders. <p>The main aims of <i>Extending and Improving a Home</i> are to:</p> <ul> <li>Guide the reader through the maze of legislation that affects most building alterations and extensions</li> <li>Show how to go about getting a project realised in terms of design, choice of contractor and construction, successfully and to budget</li> <li>Give sound technical solutions for all the elements of a project that also comply with Building Regulations</li> </ul> <p>Therefore it will be of use not only to householders but also to small builders, tradesmen such as bricklayers and carpenters, students on the first year of construction and architectural design courses at tertiary and higher education establishments and building professionals such as estate agents, building surveyors, architects and other designers.</p>
