2025 National Construction Code (NCC) – Volumes 1 and 2 Bundle The complete Building Code of Australia in one bundle — the 2025 NCC Volume One & Volume Two Bundle gives you the full technical framework for designing and constructing every class of building in Australia, from detached houses to high-rise commercial towers. Published by the Trade Institute of Victoria, these two volumes together form the Building Code of Australia (BCA) — the primary national standard covering safety, health, amenity, accessibility, and sustainability for all building types. Whether your projects span residential homes, apartment buildings, offices, retail centres, schools, or hospitals, this bundle ensures you always have the right volume within reach. What's Included NCC 2025 Volume One — Building Code of Australia (Class 2–9) Details of NCC 2025 Volume One The definitive technical reference for multi-residential, commercial, industrial, and public buildings. Volume One covers apartments (Class 2), hotels and boarding houses (Class 3), carparks (Class 7a), offices and retail (Class 5–6), warehouses (Class 7b–8), and public assembly and health-care buildings (Class 9). Key 2025 updates include: Mandatory on-site solar PV for Class 3 and Class 5–9 buildings — a major step toward net-zero commercial construction Tighter commercial energy efficiency across building envelope, lighting, HVAC, and services (Section J) with new quantitative energy-use and emissions targets Strengthened carpark fire safety — new sprinkler requirements for open-deck carparks and reduced fire-resistance concession scenarios Restructured water management provisions including new DTS provisions for apartment balconies, concrete external surfaces, and subsurface water Strengthened condensation management (Part F8) with expanded climate zone coverage, mandatory wall cavities, and revised vapour permeance requirements Optional all-gender sanitary facility pathway (Part F4) — new DTS option for Class 9b buildings Clarified Performance Solution assessment for structural reliability (B1P1) and fire safety — more consistent and robust pathways 36 new or updated Australian Standards incorporated, including fire, ventilation, and structural references NCC 2025 Volume Two — Building Code of Australia (Class 1 & 10) Details of NCC 2025 Volume Two The essential compliance document for houses, townhouses, duplexes, and non-habitable structures including garages, sheds, and carports. Volume Two sets the minimum Performance Requirements, Verification Methods, and Deemed-to-Satisfy pathways for all Class 1 and Class 10 building work. Key 2025 updates include: Expanded condensation management now covering all climate zones 1–8 — Brisbane, Adelaide, Perth, and Canberra included for the first time alongside the cooler southern and alpine zones Mandatory drained and vented wall cavities in climate zones 6, 7 and 8 to protect against moisture damage and mould New vapour permeance requirements for wall control layers, varying by climate zone and wall construction type New DTS pathway for EIFS cladding systems under Part H1 via AS 5346:2023 — simplified compliance for External Insulation and Finish Systems Updated structural referenced standards including AS 1170 (wind loads for housing) and AS 1684 (timber framing) Revised roof ventilation provisions split by insulation type — parallel vs non-parallel to the roof plane Residential energy efficiency stable until mid-2029 — 7-star NatHERS and whole-of-home budget requirements carried forward unchanged from NCC 2022 Amendment 2 Clarified structural reliability Performance Solution assessment methods (H1P1) Why Buy This Bundle? Together, Volume One and Volume Two form the complete Building Code of Australia — the foundation of every building project in the country. They are the two documents every building professional must be able to reference, and buying both together ensures you are never caught working from an incomplete or outdated picture. This bundle is particularly valuable for: Mixed-use and multi-residential projects — where apartments (Volume One) sit above or alongside commercial tenancies (also Volume One), all within a development that may also include townhouses or carparks governed by both volumes Firms working across project types — having both volumes means your team can move between residential and commercial work without switching between separate purchases Certifiers and surveyors — who assess building permits across all classes daily and need both volumes as a standing reference Educators and training organisations — delivering programs that cover the full scope of Australian construction compliance Both volumes must be applied consistently within a project — a project cannot mix NCC 2022 and NCC 2025 provisions — making it essential to have the current 2025 edition of both volumes before work commences. Who Needs This Bundle? This is the go-to reference set for: Architects and building designers working across residential, multi-residential, and commercial project types Builders and developers delivering houses, apartments, mixed-use, and commercial buildings Building surveyors and private certifiers assessing permits across all building classes Structural and civil engineers working with updated wind load, timber framing, and structural design standards Construction project managers coordinating compliance across trades and disciplines Energy assessors working across both residential NatHERS and commercial Section J compliance Access consultants advising on livable housing (Part H8, Volume Two) and disability access (Part D, Volume One) Building industry educators, TAFEs, and RTOs delivering construction, architecture, and building design programs Students in architecture, building design, construction management, and engineering
