Healthy buildings that don’t cost the Earth.
Net Zero Design is a Sustainable Building Design practice and -consultancy based in Brisbane, specialising in holistic sustainable-, healthy building- and modular design. We work collaboratively with likeminded clients, consultants and builders to create integrated, practical sustainability solutions that are inspiring and comfortable places to live in, cost-effective and future-proof.
Holistic
sustainability
Environmental, social and economic factors are interconnected. Our triple bottom line approach is at the core of every project to maximise value upfront and into the future.
We balance functional, aesthetic and environmental considerations from the start where the design direction and up to 90% of the costs are determined to create buildings that do more with less.
Healthy
living
Good air quality, thermal comfort and moisture control in the building as well as connection with nature greatly increase health and wellbeing. We specify natural and low to zero toxic materials and design for clients with special health requirements but believe that healthy design and construction should be the standard for every building.
Modular
design
Modular/prefab design offers a range of benefits such as a high level of flexibility, adaptability for future changes, quality- and cost control. Inspired by nature, our modular custom designs are efficient in planning and construction, embrace the unique features of each site and are easily personalised to suit your brief and budget.
Projects
To date our projects have included residential renovations/extensions, new custom homes, education- and master planning projects. We welcome collaboration and are open to any project that aligns with out values and philosophy. Explore selected examples here:
