Timber Framing

Also known as: timber frame, post-and-beam, heavy timber construction

A traditional wood building technique in which heavy structural timbers (typically 6×6 inches or larger) are joined with carved wood-on-wood joints (mortise-and-tenon, dovetail, scarf, brace, knee-brace) and pinned with wooden pegs rather than nails or metal fasteners. Walls between the structural frame are infilled with various materials (wattle-and-daub, brick, stone, modern stress-skin panels, straw-bale, hempcrete, light-clay-straw). A vernacular tradition in Northern European, Japanese, Korean, and Chinese architecture for over a thousand years; preserved continuously into the present and revived through the contemporary craft-and-natural-building movement.

Practical

A timber frame consists of:

  • Posts — vertical members carrying load to foundation.
  • Beams (girts and plates) — horizontal members tying posts together and supporting upper floors and roof.
  • Knee braces — diagonal members at post-beam connections, providing lateral stability.
  • Rafters and tie beams — roof structure.
  • Connectors — joints carved into the wood, secured with wooden pegs (trunnels), often without metal at all.

Joint forms:

  • Mortise-and-tenon — the canonical wood joint; a tenon (projecting tongue) on one piece fits into a mortise (slot) cut in another. Typical shoulder dimensions, peg holes, and proportions are governed by traditional rule-of-thumb engineering refined over centuries.
  • Dovetail — angled-pin-and-tail joint resisting tension.
  • Scarf — long lapped joint joining two timbers end-to-end.
  • Brace — diagonal mortise-and-tenon at post-beam corners.
  • Half-lap, lap, dado — additional joints for specific situations.

Construction sequence:

  1. Frame design — engineering, layout, joint sizing.
  2. Timber selection — species selection (oak, Douglas fir, [[kahikatea|white pine]], cedar), grade selection, and sourcing. Many timber framers specify standing-dead or slow-grown timbers for stability.
  3. Joinery — joints cut at the framing yard or on-site; precision essential.
  4. Test fit — assembly without pegs to verify joint accuracy.
  5. Raising — frame assembled on the deck, then raised by crane, gin pole, or hand-crew to vertical. Traditional barn-raising bees were collective social events.
  6. Pegging — joints driven home with wooden pegs.
  7. Decking and roofing — floor decking, roof structure, and infill walls completed.

Scientific

Why timber framing has survived: the system is extraordinarily durable. Properly framed and roofed timber buildings last centuries — the oldest standing wooden buildings in the world (Hōryū-ji in Japan, ~1,300 years old) are timber frames. [[the-joint|The joint]] geometry distributes loads more graciously than fastener-based wood construction; structures absorb seismic and wind loads through frame elasticity rather than through fastener strength.

Energy-and-environmental: timber framing uses less wood per square foot than stick framing (the modern 2×4 system) because the heavy members each do more work; the wall cavities can be filled with very-high-insulation natural materials (straw-bale, hempcrete, light-clay-straw, dense-pack cellulose). Timber frame buildings are a working example of long-life, low-embodied-energy construction.

Cultural

The Northern European medieval-and-early-modern timber-framing tradition produced thousands of buildings still standing across England, Germany, France, Switzerland, and Scandinavia. The Japanese tradition (with subtle joinery differences and emphasis on visible-frame aesthetic) is comparably ancient. The [[poconos|Pennsylvania]]-Amish-Mennonite tradition continues European-derived timber-framing as living craft.

The 20th-century U.S. revival traces from Tedd Benson’s Bensonwood Homes (NH, 1970s onward), the Timber Framers Guild (founded 1985), Rocky Mountain Workshops, the Heartwood School, and a network of working timber framers across North America. Many natural-building practitioners — straw-bale, hempcrete, cob — pair their wall systems with timber frames because the structural-frame-and-natural-infill combination is engineered, code-permittable, and aesthetically integrated.
