The solid wood panels are constructed off-site. When the site is ready they are delivered and assembled in as little as one day. That saves construction time and money. It’s also reassuring when our unfavourable weather makes it imperative to seal and protect the home as quickly as possible.
Holz100 Hotel Urthaler on the Seiseralm. Solid wood and state-of-the-art interior design by the famous architect Ingo Maurer. (www.seiseralm.com)
These hotels, built to Holz100 standards, have year round occupancy rates of 90% - far above the industry average. The best compliment for the sense of well-being, atmosphere and quality of sleep in our hotels is the high number of repeat customers. We know of no other construction method which can claim this.

... and a king’s residence, schools, kindergartens and fascinating wooden hotels to houses which become cozy and warm with a couple of logs on the fire when it’s minus 40C outside. This sustainable building with 100% wood has no limits.
A Holz100 home can be built in any architectural style possible inside and out, design possibilities are limited only by our imagination. From the polar circle to the Mediterranean, from Tokyo to San Francisco, passive houses and farmyards, garden houses and high end villas, stables...
Holz100 is also available as contemporary modular construction making it expandable and mobile at any point in the future.
What does a Holz100 home look like?
The solid wood shields the inside of the home from high-frequency radiation and it can demonstrate more soundproofing than man-made materials due to the mass of solid wood. The brilliant simplicity of nature delivers these benefits.
Ceilings in Holz100 homes perform better than concrete and steel against fire. The wood contains no materials which are destroyed by water. The solid block remains elastic and pliable through earthquakes.
Protection from the elements
Holz100 homes have withstood fires, flooding and earthquakes. The homes have top fire protection values as the solid blocks of wood do not burn but simply char on the outer surface.
The Filmarchiv Austria manages the largest film collection in the country at its facility in Laxenburg, near Vienna. It is the first film archive in the world made completely of wood from local, sustainable forests and featuring solar-powered climate control.
Holz100 house with log casing – here old log home frailties like subsidence and draughts are no longer an issue. High-tech wood in a traditional appearance.
Solid wood processed without glue uses a fraction of the production energy during manufacture compared with chemically processed wood (including OSB, CLT, plywood etc) clay bricks, cement and reinforced concrete.
It’s like having air-conditioning and heating systems with zero energy consumption. In the summer the home stays cool and in the winter it stays warm. The Holz100 factory and head office in Austria produce more energy than they consume.
...compared to a traditional framed home with the same R value. There are homes built by Holz100 that have no heating system at all. Rather they are passive solar, the heat emanating from the people in the home, the appliances in the home and the thermal mass of the wood.
The ‘passive’ house standard stick-frame wall home took 41 hours. The home with brick wall and insulation took 259 hours and the Holz100 home took 777 hours. The conclusion is that an average Holz100 home needs 1/3 of the heating system...
Recent tests of 3 wall systems with the same R-value showed the supremacy of Holz100. With the inside temperature set to 21C and the outside at -10C the heat was turned off inside the building and the researchers waited to see how long it took for the inside to fall to 0C.
The Holz100 solid wood home has the world record for heat insulation in structural materials and therefore minimal operating costs. Energy price increases are less of a worry to Holz100 homeowners.
The Technical Data
In addition to the many health and well-being benefits from Holz100, we can demonstrate hard facts relating to insulation and energy efficiency.
Letters of gratitude from people whose health has improved in our homes fill entire folders at Thoma. Holz100 hotels are consistently booked. A real sense of well-being is derived when surrounded by pure unpolluted wood with no glues or chemicals.
