What is Wood and Timber Construction?
Wood and timber construction uses processed lumber and engineered wood products as the primary structural material for buildings. It is one of humanity's oldest building methods, valued today for its renewability, workability and warmth.
Timber construction is a building method that uses wood — solid lumber, glulam, or engineered panels like CLT — as the main structural and finish material, framed as posts, beams, trusses or panels.
- •Small dimensional lumber (2x4, 2x6)
- •Studs, joists and rafters
- •Low-rise residential use
- •Fast, low-cost assembly
- •Large engineered panels and beams
- •Cross-laminated or glue-laminated wood
- •Mid-to-high-rise commercial use
- •Prefabricated, fire-resistant by char layer
Step-by-step worked examples
A builder frames a house wall with 2x6 studs spaced 16 inches (400mm) on center. Why this spacing?
Standard stud spacing balances structural strength and material cost 16 in (406mm) o.c. matches standard 4x8 ft sheathing panel dimensions Wider spacing (24 in) is used only with engineered sheathing for lighter loads
A glulam beam spans 8 meters over a community hall roof. What property allows this span beyond solid lumber?
Solid lumber is limited by tree size, roughly 6m max span Glulam laminates multiple boards, removing natural defects Engineered glulam beams can span over 30m in large halls
The Mjøstårnet tower in Norway rises 85.4 m using mass timber. What construction system enabled this height?
Cross-laminated timber (CLT) panels form floors and walls Glulam columns and beams carry vertical loads Layered wood grain directions cancel shrinkage, giving strength comparable to concrete at a fraction of the weight

Common mistakes
All wood construction is small, low-rise housing. — Correct: Mass timber (CLT/glulam) now builds mid- and high-rise buildings up to 18+ storeys.
Wood always burns unpredictably and fails fast in fire. — Correct: Large timber sections char on the surface, which insulates the inner wood and can outperform unprotected steel.
Plywood and CLT are the same thing. — Correct: Plywood uses thin veneers; CLT uses thicker solid-sawn lumber boards layered and glued at 90°.
Timber construction wastes forests. — Correct: Certified sustainable forestry replants trees, and wood stores carbon absorbed while growing.
FAQ
What is timber construction?
Timber construction is building with wood-based structural materials — solid lumber, glulam beams, or CLT panels — framed into walls, floors and roofs.
What are examples of timber construction?
Examples range from 2x6 stud-framed houses to glulam-beamed sports halls and CLT high-rises like Norway's 85m Mjøstårnet tower.
How is timber construction different from wood framing?
Wood framing is one type of timber construction (light dimensional lumber); mass timber (CLT, glulam) is a heavier engineered form used in larger buildings.
Is timber construction sustainable?
Yes — certified wood is renewable, stores carbon, and needs far less embodied energy to produce than steel or concrete.
