Mass Timber Construction
with the Thoma Holz100 System
Mass Timber Construction
Mass Timber Construction -
Naturally Built. Healthy. Durable.
Natura Domicil builds with the Thoma Holz100 system, the world’s first and only glue-, metal-, and chemical-free mass timber building system from Austria. Developed by engineer Dr. Erwin Thoma, it combines the strengths of traditional timber construction with innovative construction technology. With a Holz100 mass timber home, you enjoy maximum living quality, longevity, and sustainability.
The Thoma Holz100 approach to building the healthiest and most durable houses worldwide has proven itself in over 3,500 projects across more than 30 countries, including residences, hotels, schools, hospitals, and office complexes.
Natura Domicil is the exclusive partner of Thoma Holz GmbH on the Balearic Islands.
Key Benefits
How the Thoma Holz100
System Stands Out?
The Thoma Holz100 system uses the natural properties of moon-phase wood and is built entirely without toxins. As a result, the mass timber walls do more than structural work: they regulate temperature and humidity at the highest standard, shield against noise, fire, and EMF exposure — all without extra insulation or chemical additives.
The Healthiest Home Today
Das zu 100 % pure wood radiates a warm, inviting atmosphere; it calms the mind, fosters relaxation and well-being, dampens noise, and provides healthy indoor air quality. Wood as a material is demonstrably the healthiest building material.
50-Year
Mold-Resistance
Thoma Holz100 guarantees 50 years of mold resistance, as moon-phase wood’s natural humidity-regulating properties significantly reduce the risk of mold growth.
Energy Independence (Made Possible)
The excellent insulation properties of untreated wood significantly reduce energy consumption and enable independence from external energy sources, potentially enabling off-grid living.
Durability and Value Retention
The Thoma Holz100 construction delivers a robust, long-lasting structure for decades. Low maintenance reduces life-cycle costs, and the high quality of the home helps it retain value (potentially increasing over time).
Moon-Phase Wood
Why Moon-Phase Wood for
Building a House?
Moon-phase wood is harvested at a specific time according to traditional forestry practices and dried for 1–2 years. This yields a particularly durable material with low shrinkage and high density. As a result, the wood is unusually stable and resistant to pests, giving it an exceptional lifespan.
- 100 % natural: No glue, no metals, no toxins
- High thermal mass: thanks to its unique heat storage capacity
- Safety: high load-bearing capacity in severe weather events
- Excellent sound insulation and protection against electromagnetic pollution (EMF)
- Transparent sustainability and a circular economy
Wall Construction
Wall Construction — More Than Just Structural Support
Holz100 walls do more than carry loads: they regulate temperature and humidity, store energy, dampen sound, and offer natural fire protection — for a truly pollutant-free, healthy indoor climate.
Three Core Criteria Set Wall Thickness:
1. Energy Efficiency — Best-in-Class Savings
From a wall thickness of 17 cm, wood begins to act as a natural thermal mass. At 36.4 cm, no additional insulation is required — delivering extreme, sustainable savings on heating and cooling costs across all climates. Thermal insulation and heat storage are unmatched.
2. Long-Term Durability
While many conventional building materials must be replaced within a few decades, a Holz100 mass timber building remains stable across generations. Its average service life is considerably higher than that of conventional systems.
3. Cost-Effectiveness
Faire Baukosten, minimale Betriebskosten und keine teuren Ersatzteile. Holz100 ist eine Investition in Beständigkeit – inspiriert von jahrhundertealten Bauwerken aus Mondholz.
