The higher-density eight (HD8)
This page identifies the Building Code clauses that are being prioritised for change to facilitate higher-density housing.
The majority of Acceptable Solution and Verification Method compliance pathways are focused on low-density dwellings. Higher-density (i.e. medium- or high-density) building designs often sit outside the scope of these pathways.
Eight clauses of the Building Code – collectively known as the HD8 – have been identified as priority areas for change. Amending these clauses or increasing the scope of the associated Acceptable Solutions and Verification Methods will facilitate higher-density housing.
The HD8 consists of:
- B1 Structure and B2 Durability
- C Protection from fire
- E2 External moisture
- E3 Internal moisture
- G4 Ventilation
- G6 Airborne and impact sound
- G7 Natural light
- H1 Energy Efficiency
The HD8 clauses will be progressively amended over time to facilitate higher-density housing, through the annual Building Code system update.
