Post & Beam, or heavy timber system, is a construction technique that allows design flexibility, offering large extensions for very open façades, thus preserving free and spacious volumes.

Characterized by a sturdy wooden skeleton, usually visible from the outside and inside, the posts and beams of the structure participate in the aesthetics of the project, offering a constructive rhythm which inscribes the house volumes.

Post & Beam is a constructive system that concentrates the efforts on its primary structure, beams and posts, whose composition and design are optimized using solid or laminated glued wood, according to the design requirements.


Post & Beam Beam is usually built on a cement slab, however, by its structure, the foundation can be limited to baseboards or point supports, pillars or stakes allowing a lifting of the structure of 20cm above ground level.


Structure: consisting of a structural skeleton, the Post & Beam, as its name suggests, is formed by a set of posts and beams of large sections, organized in a frame spaced at regular intervals of 2.5 to 5 m.

Bracing: Post & Beam, with its interwoven structure, offers great rigidity. In some cases, the main structure can be finished punctually by ‘crosses of Saint Andrew’, rods (…) to brace the set. Normally, the filling between posts by Timber Frame or “structural” glazing contributes to the reinforcement of the primary structure.

Filling: integrated into the structure, the filling of the primary frame allows to enliven any empty or filled façade with a wide variety of materials and styles. Without being structural, but being able to aid the stability of the construction, this filler essentially functions as an envelope, from the glass wall, to the Timber Frame, the Laminated Logs, NATURLAM® panel or even more traditional materials.

Sealing: as for the Timber Frame, the Post & Beam includes 3 types of compactness. The waterproofness on the outside and the resistance to air and water vapor in the inner part.

Depending on the choice of filler, the combination of the different waterproofing resolutions of the construction will vary.

Insulation: depending on the type of primary structure filler, different thermal insulation assemblies are possible.

The filling of the structure can also be provided with large windows, brick walls, adobe or straw …
