Bundwerk barn

Kreil (Tann), Germany

Traditional Bundwerk barn in bavaria

The constructed Bundwerk barn is based on the traditional construction style of agricultural buildings from the 19th century in Upper and Lower Bavaria. The aim of the project was to authentically implement historic carpentry constructions while simultaneously using modern manufacturing technologies to ensure an economically viable realization. LIGNOLOC® wooden nails by BECK can be driven in with pneumatic nailers and enable durable wood-to-wood connections without the use of metallic fasteners.

Tradition and innovation go hand in hand.

The structure was designed using CAD, while most of the timber fabrication was carried out using a modern joinery system. Due to the natural twisting of the structural timber, the dovetail lap joints were traditionally crafted by hand to ensure the precise execution of these historic timber connections. The traditional board-and-batten cladding was fastened using LIGNOLOC® wooden nails by BECK.

TRADITIONAL TIMBER CONSTRUCTION

Only solid structural timber was used: spruce for the columns and purlins, pine for the Bundwerk and knee braces, and larch for the sill beams. To enable spans of around six metres, the roof structure was designed with a ridge beam and a secondary ridge beam below it. Cross braces were arranged between these elements and structurally connected using dovetail joints and wooden nails.

Innovative fastening with Lignoloc® WOODEN NAILS

The use of LIGNOLOC® wooden nails by BECK creates durable wood-to-wood connections that integrate seamlessly into traditional timber construction. The fastening elements are made entirely of wood, enabling monomaterial structures without metallic fasteners. This eliminates corrosion risks while simultaneously reducing thermal bridges. In addition, the construction remains fully recyclable and supports building in accordance with the principles of the circular economy.
