Principles for Responsible Timber Construction Implementation Framework logo

Designers shape the creative and technical possibilities of timber buildings.

The Framework helps you apply circular design principles, optimise low-carbon performance, and showcase the material’s aesthetic and structural potential. It offers strategies and tools to balance safety, beauty, and sustainability – empowering design teams to lead the transition toward regenerative architecture and influence client ambition at every stage.

Harness timber’s full potential. The Framework equips designers to deliver circular and regenerative buildings that redefine sustainable architecture and inspire industry change.

Actions for Designers

Phase 1 Strategy 1.1 Designers

Embed carbon benchmarks into conceptual design tools and cost models

Sub-action

Use early-stage carbon assessments and benchmarked carbon data to inform material choices, structural systems, and building geometry for optimum embodied emissions performance.

Principles included in this strategy
  • Accounting for Whole Life Cycle

  • Accounting for Whole Life Cycle

Phase 1 Strategy 1.1 Designers

Integrate embodied carbon calculations into early project briefs, feasibility studies and cost modelling tools

Principles included in this strategy
  • Accounting for Whole Life Cycle

Phase 2 Strategy 2.1 Designers

Commit to a timber option or timber-hybrid systems in concept design, considering key early decisions (construction type, fire resistance ratings, spans and grid, acoustic performance and MEP integration). Avoid later “timber swaps” that may compromise efficiency

Principles included in this strategy
  • Extending the life of existing buildings
  • Accounting for Whole Life Cycle

Phase 2 Strategy 2.2 Designers

Develop reuse-first design alternatives; create parallel adaptative and reuse concept schemes that integrate mass timber for extensions and retrofits alongside new-build options in initial design studies

Tools and Guidance
Principles included in this strategy
  • Extending the life of existing buildings
  • Maximising the carbon storage potential of wood

Phase 2 Strategy 2.2 Designers

Show flexibility around timber sizing and species to adapt to available stock in reclamation outlets

Principles included in this strategy
  • Extending the life of existing buildings
  • Maximising the carbon storage potential of wood

Phase 2 Strategy 2.2 Designers

Show modular, flexible – to create the “cascade”

Sub-action

Design around modular grid systems and dry connections to allow safe disassembly, upgrading, or expansion.

Principles included in this strategy
  • Extending the life of existing buildings
  • Maximising the carbon storage potential of wood

Phase 2 Strategy 2.2 Designers

Specify durable, reusable details that extend building lifespan and maximise circular value

Principles included in this strategy
  • Extending the life of existing buildings
  • Maximising the carbon storage potential of wood

Phase 2 Strategy 2.2 Designers

Use reversible or dry connection details (bolts, screws, clamps) instead of adhesives or glues for component accessibility and replacement

Tools and Guidance
Principles included in this strategy
  • Extending the life of existing buildings
  • Maximising the carbon storage potential of wood

Phase 2 Strategy 2.3 Designers

Select species and systems based on carbon intensity and durability

Tools and Guidance
Principles included in this strategy
  • Accounting for Whole Life Cycle
  • Ensuring sustainable forest management

Phase 2 Strategy 2.3 Designers

Smart specs and sourcing certifications

Sub-action

Specify traceable, sustainably managed timber with recognised Environmental Product Declarations (EPDs) and sustainable forest management (SFM) certifications in all spec packages.

Principles included in this strategy
  • Accounting for Whole Life Cycle
  • Ensuring sustainable forest management

Phase 2 Strategy 2.5 Designers

Incorporate moisture control, protective detailing, and replaceable layers to safeguard durability

Principles included in this strategy
  • Accounting for Whole Life Cycle
  • Maximising the carbon storage potential of wood
  • Promoting a timber building bioeconomy

Phase 4 Strategy 4.2 Designers

Use prefabrication and other deisgn methods for structural timber components to reduce waste and improve quality control

Principles included in this strategy
  • Accounting for Whole Life Cycle

Phase 4 Strategy 4.2 Designers

Ensure all design tolerances and detailing protect timber from moisture and damage during assembly

Principles included in this strategy
  • Accounting for Whole Life Cycle

Phase 5 Strategy 5.3 Designers

Participate in industry-wide benchmarking or open-source databases for timber performance

Principles included in this strategy
  • Promoting a timber building bioeconomy

Phase 5 Strategy 5.3 Designers

Participate in industry-wide benchmarking or open-source databases for timber performance. Share lessons learned with industry networks and peers to advance collective understanding of responsible timber delivery
