Amended AS 1684 Residential timber framing in NCC 2025
NCC references amended versions of AS 1684 Parts 2, 3 and 4. It’s important for builders and designers to understand what’s changed and how it affects timber framing on site.
The updates introduce new Deemed-to-Satisfy pathways for structural timbers and engineered wood products, align wind classifications with AS/NZS 1170.2, and recognise systems such as glue-laminated timber members and nail-plated roof trusses.
This in-depth resource outlines the practical impacts across framing, bracing, fixing and tie-down. It also provides the key updates to Part 4 (simplified) which affect strip flooring, decking and roof framing provisions.
As NCC 2025 adoption dates differ across states and territories, staying across the updated standards is essential for compliance and risk management. Access clear, builder-focused guidance and ensure your timber framing practices align with the latest national requirements.
