A Perth-born limewash paint with twenty years of history, genuine sustainability credentials, and a finish that moves with the light.
There is a version of sustainable design that is mostly about substitution. Swap the synthetic for the natural. Choose the low-VOC option. Tick the box and move on. We have been guilty of that thinking, and we are working to move past it.
As a studio, we are in the middle of a genuine shift; studying sustainability more formally, interrogating how we source, and asking harder questions about the materials we put into people’s homes. Part of that has meant returning to products we have always liked and understanding them more deeply. Bauwerk Colour is one of them.
We have specified Bauwerk on and off for client projects over the years, drawn to the finish without always being able to articulate the full reasoning. Looking at it now through a more deliberate lens, the case is clearer than we expected.
Bauwerk is a Perth-founded, Australian-owned limewash paint company that has been making natural lime paint since 2003. The base is lime putty; limestone that has been heated, cooled, and mixed with water, combined with pure mineral pigments and nothing else. No plastics, no synthetic binders, no VOCs. But what makes it genuinely interesting from a material standpoint is what happens after it goes on the wall.
The paint cures not by drying but by carbonation. It absorbs CO₂ from the air and slowly converts back into calcium carbonate; in other words, it becomes stone. Millions of micro-crystals form during that process, and they are what give the surface its characteristic depth and luminosity. A wall painted with Bauwerk at 8am is not the same wall at 3pm. That quality, a material aliveness, is increasingly something we look for when specifying finishes. Surfaces that reward attention rather than just sitting there.
From a sustainability standpoint, lime paint fits the thinking we laid out in our first journal piece: understanding the whole life of a material. Bauwerk has low embodied energy, zero VOCs, and no synthetic content that will off-gas into a home or complicate disposal later. It ages gracefully, and if a wall needs repainting in twenty years, it can accept another coat of limewash without stripping back.
For Ikigai House, we are specifying Bone, a warm, complex white that sits somewhere between chalk and cream depending on the light. It has a softness that no standard paint finish could achieve. We will share more of how it reads in context once the build is complete.
There is also something worth noting about Bauwerk’s origins. As we think more deeply about our sourcing, the question of the supply chain has become more pressing for us. Bauwerk is made in Western Australia. That is a meaningfully shorter chain than most European or American natural paint brands with comparable credentials, and it means we can specify something with genuine sustainability intent without the irony of shipping it across the world to get here. Where a local option is genuinely excellent, we want to support it.
We are not suggesting limewash paint is the right finish for every project; it requires proper surface preparation, a specific brush, and some patience with the application process. But for the projects where the material palette and the brief support it, we think Bauwerk deserves to be the considered default rather than the occasional choice.
If you are mid-brief and weighing up your wall finishes, the sample pots are absolutely worth it!
