Building an 8-Star Energy Efficient Home
A Practical Guide to Sustainable Living in Australia
$49 [BUY NOW — INSTANT ACCESS]
Most homes in Australia are built to the minimum.
Minimum insulation. Minimum glazing. Minimum thought about how the sun moves across your block or how the rooms will feel in July or February.
And then people move in and wonder why they’re running the aircon constantly, why certain rooms are always freezing, why the energy bills keep climbing, and why the house just never quite feels comfortable.
It’s not bad luck. It’s a design problem. And it’s almost always preventable.
I built an 8-star energy-rated home in Wagga Wagga.
Not because I had an unlimited budget. Not because I’m an engineer or a building scientist. But because I wanted a home that actually worked, one that stayed comfortable year-round, cost less to run, and was built with real thought about how my family would live in it every day.
Getting there meant learning things I wish someone had told me at the start. Things about airtightness, orientation, insulation layers, glazing types, vapour membranes, slab systems, and how to work with trades who’d never built to this standard before.
This ebook is everything I learned, written in plain language, with no jargon and no fluff. It’s the guide I wish I’d had when I started.
What’s inside
9 chapters and a bonus resources section covering the entire journey from first decisions to living in the finished home.
Introduction — Why I built to 8 stars, what the learning curve looked like, and who this guide is for.
Chapter 1 — What an 8-star rating actually means, how NatHERS works, and the real difference between a 6, 7, and 8-star home.
Chapter 2 — How to design for energy efficiency from day one, including orientation, zoning, cross-ventilation, and the decisions that cost nothing but make everything work better.
Chapter 3 — The construction choices that make or break performance, insulation systems, airtightness, Pro Clima wraps, and double glazing.
Chapter 4 — Sustainable fixtures and fittings, from heat pump hot water and all-electric appliances to solar planning and LED lighting.
Chapter 5 — Material and finish selections that support sustainability, air quality, and long-term durability, including what we chose and why.
Chapter 6 — Heating, cooling, and ventilation in an all-electric home, and how our house actually performs in Wagga’s extreme climate.
Chapter 7 — Real budget figures, where to invest and where to compromise, how to find trades who get it, and the mistakes I’d avoid next time.
Chapter 8 — What it actually feels like to live in an 8-star home every day. The calm, the bills, the silence, the seasons.
Chapter 9 — Practical tips for anyone starting out, questions to ask your builder, tools and rebates, and the top 10 things I’d tell my past self.
Bonus — Floor plan ideas and a simple sustainable building checklist.
Throughout every chapter, clickable links take you deeper into specific topics via real build documentation and blog posts from my own project.
This guide is for you if:
You’re planning a new build and want it to perform, not just look good.
You keep hearing terms like passive design, thermal mass, or NatHERS and want someone to explain them simply and honestly.
You live in a regional area where the climate is extreme and the standard build advice just doesn’t cut it.
You want to make confident decisions before you spend money on documentation, trades, or materials.
You’re tired of conflicting advice and want to hear from someone who has actually done it.
This is not:
A dry technical manual full of building codes and compliance requirements.
A glossy coffee table book with no practical application.
Generic sustainability advice that could apply anywhere to anyone.
This is a real account of a real build, with real decisions, real costs, and real outcomes, written by an interior designer who has spent years working in and around the building industry.
About Katrina
I’m an interior designer based in Wagga Wagga, working full-time for a prefabricated modular building company specialising in net-zero and sustainable design. I’ve spent years helping people make better decisions about their homes, and this build was my chance to put everything I believe into practice.
The 8-star home I built in Wagga is now my family’s home. I live in it every day. Everything in this guide comes from that real experience, not theory.

Frequently asked questions
Is this relevant outside of NSW? Yes. While some regulatory details reference NSW’s BASIX requirements, the design principles, construction choices, material selections, and lived experience apply across all Australian climates and states.
Do I need to be building right now to benefit from this? Not at all. If you’re in the planning stage, in the middle of a build, or just thinking about what you’d do differently next time, this guide will give you something useful.
Is this suitable for renovators as well as new builds? Yes. While the build journey focuses on a new home, most of the chapters on insulation, airtightness, glazing, materials, and energy systems apply directly to renovation projects too.
What format is the ebook? It’s a web page you access after purchase with your personal login. Everything is readable on desktop, tablet, or mobile.
Can I share access with my partner or builder? Your login is personal to you. If your partner wants access, they’re welcome to purchase their own copy. For builders, the guide is a great resource to share key chapters as conversation starters.
Still not sure?
Think about the last time you made a decision on your home without enough information. The tile you wish you’d chosen differently. The layout that doesn’t quite flow. The room that’s always too hot.
For $49, this guide gives you the thinking behind a home that avoids all of that.
