Wellbeing
Maximizing Woods Nature
Built entirely from pine wood harvested using a traditional winter method during the waning moon phase. At this time, trees are in sap rest, with moisture bound within the cell structure rather than freely present in pores and cavities. This results in lower sugar content, making the wood naturally more stable, resilient, and resistant to fungi, insects, pests, and long-term deterioration, without the need for chemical preservatives or contaminating treatments.
Toxin Free Environment
The construction of untreated natural materials releases no harmful VOCs or toxic emissions. It regulates humidity, prevents condensation, trapped moisture, and mold formation. The result is a pure indoor atmosphere that improve deep sleep, recovery, heart health, cognitive clarity, and long-term physiological balance.
Wellbeing Biohacking Potentials
Natural living environment may be particularly supportive of rest, sleep, and recovery for individuals who are sensitive to their surroundings, including those affected by allergies, respiratory sensitivities, or heightened environmental awareness. It also aligns well with lifestyles centered on physical performance, regeneration, self-optimization and biohacking-oriented lifestyles
Glue-Free Construction
The entire construction unites ancestral wisdom with modern precision and mastery of woodcraft. Minimalistic designed and engineering with mechanical connections including sophisticated expansion joints. Except for the sliding door and windows, no glue, adhesives or surface coatings are used, allowing the structure to expand naturally, breathe, ventilate, and dry completely.
Electromagnetic Shielding
The solid wood walls and vacuum glass contribute to a reduction of electromagnetic field (EMF) exposure, including high-frequency radiation from sources such as mobile networks. This supports a calmer indoor environment, which some individuals may perceive as more conducive to rest, sleep, and recovery. Using a broadband RF meter, measurements recorded high ambient electromagnetic radiation levels exceeding 14,000 µW/m² outside the structure. Inside the COCOON, measurements were significantly lower, registering below 50 µW/m², even with the sliding door open.
Thermal & Sound Insulation
The mass of the solid wood walls and the efficiency of the vacuum glass with a insulation performance superior to conventional triple glazing, provides effective thermal and acoustic insulation. Solid wood acts as a natural thermal buffer, storing heat and releasing it gradually, while also dampening sound through its density.
Heart Rate Reduction
German, Austrian and Swiss Institutes like TUM, JOANNEUM and ETHZ explore the science of wood, proofs that sleeping and living in untreated wood environments can lower heart rates, potentially saving up to 3,500 heartbeats per day, equivalent to an hour of cardiac “work".
Hypoallergenic Materials
Pleasant and balanced temperature regulation and comfort throughout all seasons. A pure wool blanket naturally regulates warmth, absorbs moisture, and remains fresh over time. It is inherently flame-retardant and benefits from natural self-cleaning properties. The mattress is filled with wild-grown kapok and encased in an untreated cotton cover. It is naturally breathable, hypoallergenic, and moisture-repellent.
Circadian Rhythm & Optimal Sleep
Following insights from neuroscience and sleep research, such as those shared by Andrew Huberman, exposure to early morning daylight, evening light, and the avoidance of artificial blue-light exposure at night support the body’s natural circadian rhythm. This can help regulate hormonal cycles, support immune function, and promote deeper, more restorative sleep, forming a foundation for recovery, cognitive performance, and overall wellbeing. COCOON wellbeing architecture makes it easier to build a lifestyle that encourages discipline and healthy daily habits.

COCOON on a MAN TGE Flatbed
Produced by family-run workshops in the German Alps, Since 1991 with experience dedicated to glue-free moon wood furniture and since 2018 construction of Thoma.at wood houses. This rare & privilege expertise is practiced by only a few craftsmen in Germany, with comparable traditions preserved mainly in Switzerland, Austria, and Japan.
Moon Wood
Moon Wood is a special type of harvesting timber during the cold winter months, specifically from the waning moon phase up to the new moon. During this period, trees are in sap rest, with water tightly bound within their cells rather than freely available in pores and cavities. This results in wood that dries with minimal shrinkage and swelling, reducing cracks and warping.
Additionally, moon wood contains less sugar during the waning moon phase, making it naturally more resistant to fungi, worms, and insects. This inherent protection eliminates the need for conventional, toxic wood preservatives, benefiting both the environment and human health.
This traditional harvesting method was used in building ancient temples and mountain huts, whose durability and resilience are still evident today.
Ancient Inspiration
by Japanese temples and alpine wooden houses that have stood for centuries, a traditional wisdom preserving techniques proven through time.
Free of Glue
Allows the wood to breathe, dry, and move naturally, avoiding internal stress, cracks, contamination, and deterioration.
Master Craftsmanship
The craft demands decades of deep knowledge and hands-on training, making these skills rare and increasingly exclusive in today’s accelerated industry.
Specialized Skills
Every piece of wood is hand-selected and consciously oriented to maximize structural stability, durability, and aesthetic consistency.
Expansion joints
Engineered with adaptable tolerances and mechanical connections, free from adhesives and surface coatings, allowing the wood to adapt, breathe, expand, and dry naturally, preventing cracks and ensuring long-term stability.
Flexible structure
Solid-wood walls and floors form a glue-free, resilient core that absorbs physical torsion and climatic stress.
40+40 mm walls
The solid core of the COCOON Freelancer uses an amount of 100% solid wood equivalent to roughly 18 tables measuring about 200 × 100 × 4 cm. A similar volume of wood is also required for the exterior structure.
20 mm furniture
The interior is crafted from light and stable glue-free panels, designed to maintain consistent purity, breathability, and material integrity.
Weather resistance
The untreated exterior forms a protective gray patina over time and can be replaced if it deteriorates.
Water repellent
It is carefully detailed without screw intrusion, or end-grain exposure to prevent water absorption, accumulation, remain ventilated and dry completely.
Natural protection
The wood develops a gray patina through aging, making it weather-resistant and protecting the core from water and sun rays.
Dried calmly
The wood is dried for years and naturally until it reaches the optimal stability for long-lasting properties.
Winter harvested
Each tree is harvested only during the winter sap-rest period from the waning to new moon phase, reducing insect presence, avoiding chemical treatments, and minimizing deformation naturally.
Local source
Spruce and larch or exclusive alpine spruce are sourced from local forests cared for by the same families for generations, ensuring sustainable stewardship, exceptional wood quality, full traceability, and minimal transport impact.

Construction
Traditional Heritage
Produced by family-run workshops in the German Alps, with over 30 years of experience dedicated to glue-free wood construction. This rare & privilege expertise is practiced by only a few craftsmen in Germany, with comparable traditions preserved mainly in Switzerland, Austria, and Japan.
Building Thoma Houses
Residential building constructed entirely with the Holz100 system, worldwide, ranging from small "Tiny Houses" to multi-story office towers.
Radiation Shielding
These walls block up to 99.9% of high-frequency radiation (such as from cell towers) while allowing the Earth’s natural magnetic field to remain intact.
Safety
These walls offer high fire resistance (up to F180) and significant resilience against earthquakes and storms.
Psychological Comfort
The natural wood surfaces contribute to lower stress levels, improved sleep quality, and a general sense of vitality.
Heart Rate Reduction
Medical studies indicate that living in these solid wood environments can lower heart rates, potentially saving up to 3,500 heartbeats per day (equivalent to an hour of cardiac "work").
Rapid Installation
A typical single-family house shell can be erected and made rainproof in few days, significantly faster than traditional masonry or brick methods.
Carbon Sink
A typical family home built with this system can remove approximately 20,000 kg of carbon from the atmosphere.
Hypoallergenic
The use of "moon wood" makes the walls naturally resistant to fungi and pests, significantly reducing household dust and providing a safer environment for allergy and asthma sufferers.
Prefabrication Precision
Walls are manufactured in a computer-controlled factory setting with millimeter precision, allowing them to slot perfectly into position (using a groove and joist system) for immediate assembly.
Efficiency
Site preparation and foundation work can occur simultaneously with factory wall production, further compressing the project schedule.
World Record Insulation
Patented air pockets between wood layers provide insulation that is twice as effective as standard glued wood, enabling "passive house" standards without additional synthetic insulation.
Insulation
The thick solid wood mass (up to 36cm for exterior walls) provides high thermal storage, naturally regulating indoor temperature and humidity.
Health
They are certified to be free of VOCs and toxic off-gassing, creating a hypoallergenic living environment.
Cradle to Cradle Gold
It is one of the only construction materials worldwide to achieve this certification, meaning the walls are 100% recyclable and produce zero hazardous waste.
Psychological Comfort
The natural wood surfaces contribute to lower stress levels, improved sleep quality, and a general sense of vitality.
Glueless Construction
Instead of toxic adhesives or nails, the layers of wood are held together by beech wood dowels.
Multi-Layered Walls
The walls consist of several layers of boards arranged vertically, horizontally, and diagonally to provide structural stability and strength.
Winter harvesting
Trees are cut in the autumn and winter months, when they are naturally hibernating.
Locally Sourced woods
Spruce, Pine, Larch, and Swiss Stone Pine (Zirbe)—sourced from the manufacturer's local regions, minimizing transport emissions.
Sap Levels
According to the "moon wood" theory (which aligns with historical records from figures like Julius Caesar and Pliny the Elder), the moon's gravitational pull influences sap levels in trees much like it does ocean tides. Felling during the waning moon ensures the sap content in the tree is at its absolute lowest point.
Free of glue
Mechanical joinery allow breathe, dry without deterioration.
Master craftsmanship
Decades of deep knowledge and hands-on training.
Expansion joints
Allow the wood to adapt, expand and move naturally preventing cracks.
Natural protection
Gray patina protecting the core from water and sun rays by aging
Dried calmly
until it reaches the optimal properties.

This rare & privilege expertise is practiced by only a few craftsmen in Germany, with comparable traditions preserved mainly in Switzerland, Austria, and Japan.
Ancient Inspiration
by Japanese temples and alpine wooden houses that have stood for centuries, a traditional wisdom preserving techniques proven through time.
Free of Glue
Allows the wood to breathe, dry, and move naturally, avoiding internal stress, cracks, contamination, and deterioration.
Master Craftsmanship
The craft demands decades of deep knowledge and hands-on training, making these skills rare and increasingly exclusive in today’s accelerated industry.
Specialized Skills
Every piece of wood is hand-selected and consciously oriented to maximize structural stability, durability, and aesthetic consistency.
Expansion joints
Engineered with adaptable tolerances and mechanical connections, free from adhesives and surface coatings, allowing the wood to adapt, breathe, expand, and dry naturally, preventing cracks and ensuring long-term stability.
Flexible structure
Solid-wood walls and floors form a glue-free, resilient core that absorbs physical torsion and climatic stress.
40+40 mm walls
The solid core of the COCOON Freelancer uses an amount of 100% solid wood equivalent to roughly 18 tables measuring about 200 × 100 × 4 cm. A similar volume of wood is also required for the exterior structure.
20 mm furniture
The interior is crafted from light and stable glue-free panels, designed to maintain consistent purity, breathability, and material integrity.
Weather resistance
The untreated exterior forms a protective gray patina over time and can be replaced if it deteriorates.
Water repellent
It is carefully detailed without screw intrusion, or end-grain exposure to prevent water absorption, accumulation, remain ventilated and dry completely.
Natural protection
The wood develops a gray patina through aging, making it weather-resistant and protecting the core from water and sun rays.
Dried calmly
The wood is dried for years and naturally until it reaches the optimal stability for long-lasting properties.
Winter harvested
Each tree is harvested only during the winter sap-rest period from the waning to new moon phase, reducing insect presence, avoiding chemical treatments, and minimizing deformation naturally.
Local source
Spruce and larch or exclusive alpine spruce are sourced from local forests cared for by the same families for generations, ensuring sustainable stewardship, exceptional wood quality, full traceability, and minimal transport impact.
Moon Wood
Moon Wood is a special type of harvesting timber during the cold winter months, specifically from the waning moon phase up to the new moon. During this period, trees are in sap rest, with water tightly bound within their cells rather than freely available in pores and cavities. This results in wood that dries with minimal shrinkage and swelling, reducing cracks and warping.
Additionally, moon wood contains less sugar during the waning moon phase, making it naturally more resistant to fungi, worms, and insects. This inherent protection eliminates the need for conventional, toxic wood preservatives, benefiting both the environment and human health.
This traditional harvesting method was used in building ancient temples and mountain huts, whose durability and resilience are still evident today.
