Prefab elements

Wall elements for a prefabricated timber-frame house are made of strength-graded wood and 100% certified materials. The wall, floor and roof elements are prefabricated in factory conditions to a maximum level minimizing the necessity of on-site works. 

Prefab houses have a low carbon footprint due to environment-friendly materials that are used in a maximally efficient way.
