You can't go wrong with the price of this book. However, if you purchase directly from the Canadian Housing and Mortgage Company (the publisher), you can also receive a glossary of housing terms which proves to be quite useful when using the book. If you're and engineering student, contractor or you just want to build your own wood frame house, this reference based on the 2005 building code is a must. However, be sure to also get your hands on the 2005 building code as this book is simply a great supplement to the code with insights and tips on how to improve the quality and cost of your construction. Overall, an easy, non-technical read with great insight and included design tables.
