Materials that support a healthier way of living.
Kiso homes are designed with materials that are durable, natural, low-emitting, repairable, and comfortable to live with. The goal is thoughtful progress: reducing unnecessary petrochemicals, avoiding avoidable indoor pollution, and selecting finishes that age with dignity.
A clear order of preference.
- Natural and mineral-based first
- Low-emitting and healthy to live with
- Durable and repairable
- Responsibly sourced
- Proven in this climate
A small palette, chosen carefully.
Wood
Structure, surfaces, and warmth — renewable, repairable, and better with age.
Lime
Breathable mineral plasters that moderate humidity and age gracefully.
Cork
Quiet, resilient, and naturally renewable underfoot.
Wood fibre
Vapour-open insulation that keeps assemblies warm, quiet, and moisture-safe.
Stone & ceramic
Mineral surfaces for the hardest-working parts of the home.
Natural oils & waxes
Finishes that protect wood while keeping it repairable and pleasant to touch.
Natural fibres
Textiles and soft surfaces without unnecessary synthetics.
Air quality is designed, not hoped for.
Source control
The most reliable pollutant strategy is not bringing pollutants in.
Ventilation
Continuous balanced fresh air with heat recovery.
Filtration
Fine filtration for supply air, wildfire smoke, and seasonal dust.
Humidity
Assemblies and systems that keep indoor humidity in the healthy band.
Moisture-safe construction
Details designed to dry, so mold never gets a foothold.
Designed to remain useful.
Kiso favours materials and assemblies that can be maintained, repaired, separated, and returned to useful service where practical. This means designing for access, using clear material layers, favouring mechanical and reversible connections over permanent composites when performance allows, and keeping records of what the home contains.
The ambition is for future owners and caretakers to be able to understand, adapt, recover, reuse, or responsibly renew parts of the home rather than treating them as disposable.
- Service access
- Repairable layers
- Reversible connections where practical
- Material records
- Reuse & recovery pathways
- Responsible renewal
Durability is one of the most sustainable choices.
Materials that can be repaired, refinished, maintained, and loved for decades often create less waste than materials designed for quick replacement.
