Mid-rise Timber Resources

The National Construction Code1 2016 Volume One (NCC), Building Code of Australia, Class 2 to Class 9 Buildings, allows the use of timber construction systems under the Deemed-to-Satisfy (DTS) Provisions for Class 2 (a building containing two or more sole-occupancy units (SOUs) each being a separate dwelling), Class 3 (residential buildings, other than buildings of Class 1 or 2, which are a common place of long-term or transient living for a number of unrelated persons, including hotels) and Class 5 (offices) buildings up to 25 metres in effective height, known as mid-rise construction - see figure below.]

The new provisions cover both traditional lightweight timber framing and new massive timber systems such as cross laminated timber (CLT) and consist of the use of appropriate layers of fire-protective grade plasterboard – termed ‘fire-protected timber’ in the NCC – and the use of compliant automatic sprinkler systems.

On this page you'll find links to more information and resources about designing and building to maximise the benefits of the new code change.
