Your home should support how you feel.
Most homes contain materials that quietly work against your health. We help you find out what’s in yours, and what to do about it.

Why it matters
We spend 90% of our lives indoors.
The materials around us shape the air we breathe, our sleep quality, and our long-term health. Yet most of us have never assessed what’s actually in our home.
VOCs off-gas for years
Synthetic paints, laminate flooring, and MDF furniture release volatile organic compounds long after installation. There are often no visible signs, no smell after the first weeks, and no warning on the label.
Labels are unregulated
“Natural”, “eco-friendly”, and “low-VOC” have no legal definition in the EU. A product can carry all three claims and still contain chemicals of concern. Without independent certification, the words mean very little.
Natural materials work differently
Clay, lime, solid wood, and linen regulate humidity, absorb VOCs, and support healthy indoor air. These are measurable properties backed by decades of building biology research, not marketing claims.
How it works
Three steps to a healthier home
No chemistry degree. No specialist equipment. Clear answers and an honest roadmap.
Assess your rooms
Answer guided questions about materials, ventilation, humidity, and habits room by room. A quick check takes two minutes; a full room deep-dive runs 15–20 minutes.
Get your health score
Each room receives a 0–100 score across three pillars: physical environment, chemical exposure, and biological factors. Science-backed, plain language, no alarm.
Act with confidence
Receive a prioritised renovation roadmap ranked by impact and cost. Every recommendation links to vetted natural materials and the research behind the choice.

Research foundation
Built on peer-reviewed science
Every score, recommendation, and risk flag in our assessments is grounded in published research. The Baubiologie framework was developed in Germany in the 1970s and integrates findings from environmental medicine, toxicology, and building physics. Our tools translate that knowledge into a structured format anyone can use.
Indoor VOC levels are 2–5 times higher than outdoors
VOCs and air quality
Modern building materials — synthetic paints, adhesives, PVC flooring, MDF — are the dominant source of indoor VOC exposure. Concentrations exceed outdoor levels year-round, even in rural areas.
Poor ventilation measurably affects sleep architecture
Sleep and ventilation
Elevated CO₂ from poor bedroom ventilation and synthetic off-gassing reduce REM sleep duration and increase morning fatigue — independent of noise and light.
Clay and lime regulate humidity within the healthy 40–60% range
Humidity and mould
Unlike synthetic plasters and vinyl wallpaper, clay and lime are hygroscopic. They absorb excess moisture and release it when the air dries, reducing mould risk without mechanical ventilation.
Our full evidence library covers 60+ peer-reviewed sources across VOCs, humidity, acoustics, and biophilic design.
