About Us

Building code experts backed by over 30 years of industry experience & dedicated to providing professional building consultancy services.


Integral Performance Solutions is an Australian-based building consultancy team, providing expert advice and performance solutions across residential and commercial projects.


With over 30 years of combined experience, we help builders, architects, developers, and certifiers achieve compliance with the National Construction Code (NCC) — without compromising on design or cost.

Smart Compliance

We specialise in navigating complex regulatory requirements, offering practical, compliant, and cost-effective alternatives to Deemed-to-Satisfy provisions.

How It Works

What Are Performance Solutions?


A common misconception in the building and construction industry is that the Deemed-to-Satisfy provisions are the only way to achieve compliance with the National Construction Code. However, there are alternative pathways — through a Performance Solution.

  • What is it?

    Performance Solutions provide a flexible, code-compliant approach outside the prescriptive rules of the NCC — often resulting in more innovative and cost-effective outcomes.

  • When it's Used

    These solutions are typically applied during design, certification, or approval stages — but can also resolve issues during or after construction.

  • How it Works

    We follow the NCC’s structured process to deliver tailored, practical solutions that meet the Performance Requirements of Volumes One, Two and Three.
