This publication is a comprehensive, practical, step-by-step guide and is the ideal reference tool for anyone involved in house building. The easy-to-read format follows through all the key steps involved in house construction right from setting out the site to lining out.

This guide contains practical guidelines for good timber-framed house building, with hundreds of diagrams, easy to follow tables for quick reference and bullet points for easy reading. Informative illustrations show how all the elements fit together.

Note that since the publication of this book a number of Building Code Acceptable Solutions have been amended and new Acceptable Solutions developed.

For most of us, the word 'home' means a place of comfort, a refuge, a place where we can be ourselves and relax. For people with disabilities or those growing older, home has a special importance because they are likely to spend more time there. But when physical barriers and poor design make that home difficult to live in, health, safety and happiness can be compromised.

Designing and adapting houses in a way that enables people to really live in their own home for longer makes sound economic as well as emotional sense. It will lessen dependency, lower the risk of accidents, reduce the cost to society and possibly even increase the resale value.

This guide is about houses that are not disabling. It was developed in conjunction with many people working in the health and disability fields. It is packed with diagrams and advice for building designers, builders, health professionals, homeowners and anyone involved in the design or alteration of houses for those with disabilities or the elderly.

Clay and concrete tiles have long been popular choices of roofing material, particularly in severe coastal or thermal environments. As a general rule, clay and concrete tile roofs can be expected to last 50 or 60 years before needing replacement.

Regular checks and proper maintenance are critical to keep the roof in sound condition and to keep the water out. This Good Repair Guide focuses on the repair options for isolated areas of concern. 

Approximately 10% of New Zealand households rely on rainwater collected from roofs for their water supply. Typically, these are rural residential properties but may include country schools, camping grounds, marae and other community buildings. A number of fairly simple and relatively inexpensive measures can be introduced to existing systems to improve water quality

This Good Repair Guide looks at upgrading options and maintenance requirements for existing rainwater storage systems to ensure a quality potable roof water collection and storage system is maintained. 

General wear and tear in a house often results in damage to interior wall linings. Damage can range from repairable (a picture hook pulled out or a door handle through the wall) to the catastrophic (a major leak or structural failure). 

This Good Repair Guide outlines some options for repairing existing wall linings and guidelines for when to replace a sheet or larger area of lining.

Prefinished linings (such as melamine-faced boards) are not included in this guide.
