Our advantages
Controlled costs and shortened lead times, in compliance with quality standards and environmental regulations in force.



Prefabricated house: how does it go?
The construction process of a timber frame house relies on precision engineering and rigorously controlled industrial organization. Located in Chartres, in Eure-et-Loir, Ossa Bois France collaborates with a specialized engineering office and relies on a modern production plant equipped with the latest generation machinery in Kosovo. This synergy guarantees a tailor-made design and factory fabrication protected from weather conditions, ensuring a consistency of quality impossible to obtain on a traditional building site.
Our workshop prefabrication process allows performing most of the structural work (wall assembly, integrated insulation, window installation) under optimal safety and control conditions. This modern method significantly reduces overall implementation time and optimizes resource use by minimizing construction waste on site.
Once the different modules or panels are completed and certified compliant, they are transported with the greatest care to your land. The final assembly is then carried out by our certified assembler partners throughout France. In just a few days, the water-tight and wind-tight structure is erected, ready to receive interior finishes for a fast and peaceful move-in.

Questions and answers about timber frames
Find answers to the most frequently asked questions about modular home construction and compliance with standards.
Yes, timber frame construction is particularly suitable for sloping land. Thanks to the structural lightness of wood, foundations (like concrete pads or foundation screws) are less restrictive and more economical than for traditional concrete construction, adapting perfectly to the natural relief of the ground.
The quality of the design, treated materials, and factory construction of our homes allows them to last for several generations. Modern wood structures benefit from advanced treatments against moisture and insects, offering a longevity equivalent to or greater than traditional block or brick constructions.
Each house built by Ossa Bois France benefits from all builder's guarantees required by French law, including decennial insurance (which guarantees structure and weather tightness for 10 years), the guarantee of perfect completion (1 year), and the guarantee of proper functioning of equipment (2 years).
Workshop prefabrication guarantees millimeter precision thanks to our digital equipment and constant quality control protected from weather. It also cuts construction times in half and minimizes waste, while guaranteeing flawless finishes.
