What is Timber Framing?

Deconstructing the Venerable

Timber framing is an age-old method of construction that involves using heavy timbers to create the structural frame of a building. This method of construction dates back hundreds of years, and is known for its strength, durability, and visual simplicity.


The timber frame forms a visible skeleton of a building. The frame supports the walls, floors and roof. It is an integral part of the overall structure and plays a key role in determining the overall appearance and character of the building.


Timber framing should not be confused with or likened to log homes or post and beam construction. In timber framing, design and joinery work together to hold the structure together. Pegs hold the joinery together rather than bolted steel gussets.

Joinery

Hand-cut timber frame joinery is a traditional technique for constructing buildings using interlocking wooden beams, created entirely with hand tools. It's a skill that relies on the craftsperson's experience and knowledge to create strong and long-lasting structures.

Bents

A timber-framed bent is essentially the backbone of a timber frame structure. Just like the rib cage supports and shapes the body, bents provide the core framework for the walls and roof. These pre-assembled units, typically crafted from hefty beams like posts, columns, and braces, are like giant Lego sections specifically designed to interlock and create a strong skeleton for the building.


Unlike Lego bricks that snap together easily, timber-framed bents are meticulously crafted using traditional joinery techniques like mortise and tenon. This ensures a secure and enduring connection between the beams. The bents are often assembled on the ground or in a workshop, allowing for more precise cutting and fitting by the woodworker. Once complete, they are hoisted into place during construction, similar to how you might carefully position a large Lego structure you've built.

Raising a Timber Frame

Raising a timber frame is a thrilling culmination of meticulous planning and craftsmanship. It's a process steeped in tradition, often involving a community effort that brings the structure to life. Imagine a scene reminiscent of old barn raisings, where teamwork and a shared sense of purpose take center stage.


Before the big day, everything needs to be meticulously organized. The bents (pre-assembled sections of wall and roof supports) are carefully labelled and staged for easy access. A crane is often brought in for larger and heavier frames, while smaller projects might rely on a team effort with ropes and block-and-tackle systems.

Hybrid

A hybrid timber frame is a beautiful blend of classic aesthetics and modern building practices. It takes the timeless appeal of exposed beams and handcrafted joinery from traditional timber framing and combines it with the efficiency and affordability of conventional building methods.


Imagine a home with soaring vaulted ceilings accented by massive beams in the living room, creating a dramatic focal point. This is where the hybrid approach shines. The exposed timber elements bring warmth and character to the space, while the rest of the house might utilize conventional stud framing for bedrooms, bathrooms, or utility areas.

Choosing a Wood Species

Using local wood species for timber framing is a sustainable and cost-effective building option. Local wood species are those that are native to or grown in the region where the building is located. Using local wood reduces the environmental impact of transportation and also supports local forestry and milling industries.


Many different wood species can be used for timber framing, and the specific species that are available locally will depend on the region where the building is located. Some common wood species used for timber framing include white oak, Douglas fir and white pine. Each species has its own unique characteristics such as strength, weight and appearance, which should be considered when selecting the wood for a timber frame project. Further, consideration for the specific climate and environment where the building will be located needs to be carefully weighed.
