Homes designed around the way you want to live.
At Earthy Haus, every project brings together considered design, building science and a deep understanding of place and people.

What we bring to every project
Intentional Design
Beautiful homes shaped around the people who live in them, the site they occupy and the climate they belong to.
Every project is a close collaboration, resulting in a home that feels deeply personal, considered and uniquely its own.
Building science as a core element
We integrate building science from the earliest stages of design, considering thermal comfort, passive solar design, airtightness, moisture, ventilation and energy performance as an intrinsic part of creating a beautiful, healthy and resilient home.
Passivhaus expertise
Certified Passivhaus Designer expertise applied pragmatically to new homes, renovations and high-performance projects.
A considered approach to materials
Natural, durable and low-toxicity materials selected for their performance, longevity and the atmosphere they create.
Designing for the Australian landscape
Where bushfire, solar access, topography, vegetation and climate all influence how a home should perform.
From first sketch to construction
A thorough understanding of the process from early design and planning through documentation, consultants and construction.
Before Earthy Haus...
Before establishing Earthy Haus, Karina spent more than a decade working across a broad range of residential and Passivhaus projects, developing a deep understanding of design, approval processes, building science, documentation and construction. This experience complements our projects, bringing together considered design and a practical understanding of how homes are designed, detailed and built.
