Wooden architecture refers to buildings and structures whose primary load-bearing or exterior envelope components are composed of wood. It encompasses traditional timber framing, log construction, and wooden cladding, as well as modern engineered timber products such as cross-laminated timber (CLT) and glulam used in multi-story construction.

Historically, timber has been a dominant building material in many regions due to its availability, workability, and rapid construction. Ancient wooden structures include East Asian temples and pagodas, European half-timbered houses, and Nordic stave churches. In North America, log cabins and timber-frame houses defined colonial and frontier vernaculars. Fire, rot, and insect damage shaped preservation practices and building codes.

Construction methods vary from traditional to contemporary. Timber frame and post-and-beam rely on large timber members joined by carpentry joints. Log construction stacks horizontally to form walls. Modern engineered timber uses CLT panels, glue-laminated beams (glulam), and laminated veneer lumber (LVL) to create strong, lightweight structures that can compete with concrete in many applications. Fire safety and moisture control are integral in both historical detailing and modern design, with protective finishes and appropriate detailing informing practice.

Advantages and challenges include renewability, carbon storage, light weight, and rapid assembly, along with aesthetic and acoustic qualities. Challenges involve fire performance, moisture management, decay, and supply-chain sustainability. Proper detailing, protective treatments, and maintenance are essential for longevity.

Sustainability and preservation emphasize responsible sourcing (FSC, PEFC) and lifecycle assessment to inform timber choices. Advances in durable finishes, weather protection, and preservation techniques support the longevity of both new and historic wooden structures.
