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
Use benchmarked carbon data to inform material strategies
Tools and Guidance
Principles included in this strategy
- Accounting for Whole Life Cycle
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.
Tools and Guidance
Principles included in this strategy
- Accounting for Whole Life Cycle
Integrate embodied carbon calculations into early cost modelling tools
Sub-action
Commission pre-application carbon feasibility assessments for planning.
Tools and Guidance
Principles included in this strategy
- Accounting for Whole Life Cycle
Integrate embodied carbon calculations into early project briefs, feasibility studies and cost modelling tools
Tools and Guidance
Principles included in this strategy
- Accounting for Whole Life Cycle
Recommend hybrid retrofit approaches using mass timber and biobased materials for vertical/horizontal extensions
Tools and Guidance
Principles included in this strategy
- Extending the life of existing buildings
- Maximising the carbon storage potential of wood
Create early-stage material maps showing local responsibly sourced materials, reuse potential and carbon impacts, including low transport emissions
Tools and Guidance
Principles included in this strategy
- Ensuring sustainable forest management
- Promoting a timber building bioeconomy
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
Tools and Guidance
Principles included in this strategy
- Extending the life of existing buildings
- Accounting for Whole Life Cycle
Incorporate materials from previously deconstructed timber projects where viable, privileging best practice in wood cascading to maximise quality exploitation over time.
Tools and Guidance
Principles included in this strategy
- Extending the life of existing buildings
- Maximising the carbon storage potential of wood
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
Show flexibility around timber sizing and species to adapt to available stock in reclamation outlets
Tools and Guidance
Principles included in this strategy
- Extending the life of existing buildings
- Maximising the carbon storage potential of wood
Show modular, flexible – to create the “cascade”
Sub-action
Design around modular grid systems and dry connections to allow safe disassembly, upgrading, or expansion.
Tools and Guidance
Principles included in this strategy
- Extending the life of existing buildings
- Maximising the carbon storage potential of wood
Specify durable, reusable details that extend building lifespan and maximise circular value
Tools and Guidance
Principles included in this strategy
- Extending the life of existing buildings
- Maximising the carbon storage potential of wood
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
Select species and systems based on carbon intensity and durability
Tools and Guidance
