TIMBER FRAME AGRICULTURAL SHED

Biohabita! We took part in the construction of an agricultural shed with a structure made exclusively of wood.

Douglas fir—also known as Oregon pine (Pseudotsuga menziesii)—was used, sourced from FSC-certified forests in Les Guilleries, next to the Montseny massif. For the pegs, acacia wood was used, as it offers properties better suited to the specialized function of this element.

The timber was felled in accordance with the phases of the moon. In general, felling aims for the wood to have the lowest possible moisture content, taking advantage of the fact that depending on the lunar phase the sap concentrates in the roots and therefore its presence—in liquid form—in the trunk is reduced.

The construction was carried out using a heavy solid-timber structure with traditional joints and wooden pegs, following the timber frame method.

The frame was made by working the wood with mortise-and-tenon joints, using acacia pegs for fixing. The system ensures the structure is fully locked together, and the timber members work mainly in compression.

The only metal hardware used was at the point of contact between the timber posts and the concrete slab.

The design, structural calculations, fabrication, and assembly of the structure were carried out by Fustaeco.

The project is located in the immediate surroundings of the Sant Llorenç de Munt i l’Obac Natural Park.
