How the AlterecO2 Process Works: Sustainable, Pre-Designed Homes Made Simple
Born from a blend of smart design ideas and frustration with the limits of current building standards, AlterecO2 offers a collection of beautiful, pre-designed homes.
AlterecO2 is a forward-thinking initiative by Altereco Design, a boutique building design studio passionate about efficiency, sustainability, and smart, practical homes.
Design-to-go Packages.
Get started with a set of Design Development drawings to test your project’s feasibility with a builder. It’s a simple, low-cost way to access an architecturally designed home and decide on next steps. From there, you can engage a draftsperson or building designer to adapt the design to your site and manage permits.
Pre-designed but personalised.
For those who want full support from start to finish. We guide you through every stage, making the process smoother and more efficient than a custom design journey — saving time and fees while still delivering a tailored, high-performance home. Available to Victorian residents only.

“We were nervous undertaking a building project for the first time, not knowing how to start and what the process would look like. From our first meeting with James and Claire, we knew we were in great hands. They gave a clear roadmap of the design process and expected fees at each stage, as well as answering any and all newbie questions we had. During the build process they were a dream to work with, although there were almost no issues to deal with because the design stage had been so thorough! We wouldn’t hesitate to work with them again in future”
