Homes can be prone to noise pollution, fire, radiation pollution, earthquake, flood, mould, unhealthy air quality and inefficient insulation. Instead of pollution filled chemicals and adhesives, our houses are made as a solid wood shell.

Holz100 is an example of cradle to cradle in its purest form. The wood in a Holz100 home is always clean wood – a valuable material for generations to come. It can be un-assembled, reused for other applications, or as fuel or compost at the end of its useful life, without any environmental consequences.
Thoma Holz100 is such a solid wood construction system. All wood used in a Holz100 home is harvested from sustainable forests. The trees are cut during sap rest periods in the correct lunar phase, a tradition dating back thousands of years, which preserves wood against mold and insects.
There are temples in Japan over 1600 years old constructed of wood with wooden peg connectors. These buildings have outlasted storms and earthquakes proving the effectiveness of wood to wood connections and solid wood construction.

Your benefit: The healthiest house in the world. Our aim: To build the healthiest house in the world – with the highest standards of build. Our solution: Thoma Holz100 – a solid, no glue, no chemical solid wood shell. A pure wood surround with no additional pollutants.
The powerful testimonials from thousands of happy Holz100 customers are our best advertisement. Enjoy the contents of this brochure – it explains the benefits in detail and how to progress plans to design and build a Holz100 home.
The patented Thoma Holz100 construction method wraps the home’s inhabitants in pure solid wood with no chemical pollutants. This combines both state-of-the-art thinking with enduring natural characteristics of wood at its finest.
With its non-glued solid wood shell, a Holz100 house has impressive results (and a few world records) in heat insulation, air-conditioning, energy savings, indoor air-quality, soundproofing, protection from radiowaves, fire protection and earthquake security.
For over 20 years we have had this as our vision and today can share many successful examples of our work. A new era of quality wood construction was heralded by the invention of Holz100 by Thoma.
A sense of well-being
Can a house be the fuel for health and well-being? People increasingly want their home to be an oasis of health and well-being. At Thoma, we are working towards this on their behalf. The “WOODCUBE”, developed as part of the IBA Hamburg 2013, is a prominent example of this approach. By making the switch from CLT to Holz100, WOODCUBE was able to achieve high quality building standards such as saving up to 95% energy.
Through a smart approach and the use of highly modern technology, it has been transformed into a smart material that can define inner city housing construction. Without the toxicity of CLT and low energy efficiency of log homes, Holz100 brings no compromise.
Wood has been used as a construction material for thousands of years. However, log homes bring inefficient thermal insulation due to the nature of is construction and CLT uses glues, toxins and preservatives - making Holz100 the best option for timber buildings.
Nevertheless, the DGNB nominated the “WOODCUBE” for the 2013 German Sustainability Prize, which it shared with two other buildings. Woodcube used Thoma Holz100, the best choice from its competitors: CLT and log homes.
... on the basis that it did not want the “WOODCUBE” to be placed in the same category as other buildings that had received the Gold Seal. Holz100 is in the same category as CLT, and performs much better than log homes, but is one of its kind with a waste-free life cycle and surpasses all building standards.
This would have been possible if a preliminary investigation had been carried out, as its consistent environmental focus would have met the sustainability criteria, with energy savings of up to 95 per cent. After discussions with the DGNB, DeepGreen turned down the Gold certification...
... makes an outstanding contribution to sustainable building typologies, while venturing far beyond prevailing construction standards and the current discourse surrounding sustainability in architecture. It is worth noting that the project did not receive the German Sustainable Building Council (DGNB) Gold Seal.
The restructuring within the project company also led to delays in the planning process. Ultimately, the project benefited from the difficult circumstances that it underwent on the way to its final concept, and the “WOODCUBE” ...
However, the new team put together by DeepGreen thoroughly matched the quality of that in the competition.
Since repeated attempts were made throughout the project to implement genuine innovations, the planning process often reached a point where the whole project came into question. Process Evaluation+
The stated aim of the IBA Hamburg has always been to implement the project using the team that won the competition. This did not happen in the case of the “WOODCUBE”. ... to that of a Passive House. If we look at the building’s energy requirement purely in terms of the numbers, it comes to 18 kWh/m2 per year, which is roughly equivalent to the Passive House standard.
... the positive material properties of solid wood construction in terms of energy efficiency cannot be attained through conventional methods. The actual energy consumption is likely to be similar ...
