2nd May 2018: With sky-high house prices and a growing shortage of homes to buy*, Haynes has given its best-selling Home Extension Manual a comprehensive refresh to help its readers join thousands of other homeowners who have embraced the ‘improving, not moving’ mantra.

Haynes’ third edition of the Home Extension Manual offers a step-by-step guide explaining how to keep control of your building project with no nasty surprises - so you get the extension you really want completed on time and on budget. From design and planning through to snagging and completion, Haynes breaks down the complexities of building home extensions into bite-size chunks showing readers how the whole process works. 

What’s more, with renewable energy on the rise**, the updated manual includes everything there is to know about energy-efficient design as well as explaining all the options for renewables. The new manual also covers important topics such as CAD, highly glazed extensions, SIPS, timber frame and traditional oak construction, basements, underfloor heating, liquid screeds, and wood burning stoves.

Haynes’ Home Extension Manual explains how to get planning permission - and what you’re legally allowed to build without it. It also shows how to comply with the Building Regulations and avoid common mistakes. As well as showing how to successfully project manage developments, readers can see how to negotiate generous trade discounts, how to spot bad workmanship (before it gets out of hand) and how to avoid getting into disputes with rogue builders.

With home extensions being the most frequent request architects and contractors receive*** , the updated manual cuts out the middle man, boosts confidence and shows readers how to stay in control and save money.

Illustrated with hundreds of coloured photos showing real building projects as they progress, it’s a comprehensive guide to home extensions that is easy to read and accessible to everyone. 

Director of his own chartered surveying consultancy and a well-known writer and speaker at RICS events, author Ian Rock is a leading expert in the home improvement field. Talking of the book, Ian said: 

“I felt compelled to revisit this manual because times have changed. Many young adults of the ‘boomerang generation’ are coming home to live with their parents, with consequent demands on living space. For many households, home extensions have got to be the solution.  What’s more, there’s been leaps and bounds in construction when it comes to technology and sustainable energy, and we thought it crucial to update the book with these latest developments. 

 “Some readers may choose to do some of the building work themselves; others may simply find it useful to know the correct way to do things, rather than taking the builders word for it! So it’s perfect for anyone who dreads getting the builders in. The manual aims to give readers the confidence to deal directly with main contractors and trades, and should provide a solid foundation to successfully run a building project without the cost of employing a professional project manager.”
