Wie man ein nachhaltiges Modulhaus baut | SWR Handwerkskunst

Wood is the building material of the future. It's not just furniture or floors that are made of wood - many people live in entire houses made of wood. Siblings Lisa and Timo Gelzhäuser build particularly sustainable wooden houses. Like many forests in Germany, their family forest in the Sauerland region has a bark beetle problem. Many spruce trees had to be felled. In order to continue using the wood in the most environmentally friendly way possible, they build modular houses. Customers put together their dream house on the computer. The individual modules are screwed together in a wood workshop. Here, Timo Gelzhäuser also lends a hand with sawing, screwing and sanding. To avoid the use of adhesives as far as possible, the timbers are wedged together with plug-in joints. All kinds of machines are used, from large cranes to small cordless screwdrivers. This is how walls, roofs and facades are created. In the end, the long, round trees become an entire house, in which you can still smell the fresh spruce.
