This project, called “Haus Tür an Tür”, emphasises social, ecological, and economic efficiency. The building, designed by Streidl, Gilg, Wolff Architekten, uses prefabricated exterior walls in timber frame construction with Kerto LVL. Wooden elements were the key to streamline the construction process and smart designs with long-lasting materials made the project cost-efficient.
Wood was chosen as the main material for its ecological and technical properties. The construction project emphasises resource efficiency and healthy living environments with a high proportion of timber. The building’s foundation consists of load-bearing and non-load-bearing exterior walls in timber frame construction, with a massive core providing structural support. Kerto LVL was used in load-bearing wall structures and a total of 500m3 of wood was used in the project.
“The client desired an ecological construction method, excluding concrete and steel,” said Manfred Gilg from Streidl, Gilg, Wolff Architekten. “By choosing wood, we selected a renewable resource that stores CO2 throughout its entire lifespan.”
Kerto LVL supports cost- and material-efficient construction, which is becoming more important in the building industry. Kerto LVL’s high strength and stability make it ideal for prefabrication, and in addition, wall elements built with LVL are lighter and slimmer compared to massive timber elements because less wood is needed to manufacture the elements.
“The precision of Kerto LVL is especially valuable during prefabrication,” said Wolfgang Krettenauer, project manager from Gumpp & Maier GmbH. “Minimal deviations help us streamline our processes and allow us to create high-quality components without mistakes. These prefabricated wall elements, including windows and facade cladding, are quickly assembled on-site, reducing total construction time.”
