Design for Disassembly (DfD) 

Here’s a deep dive into Design for Disassembly (DfD) in timber construction—an approach that’s revolutionizing sustainability and circularity in architecture:

🪵 What Is Design for Disassembly (DfD)?

DfD is a design philosophy that ensures buildings can be easily dismantled, allowing components and materials to be reused, recycled, or repurposed at the end of their life cycle. In timber construction, this means:

• Using mechanical fasteners (like bolts or connectors) instead of adhesives

• Designing modular elements that can be separated without damage

• Documenting materials and connections for future recovery

• Reducing waste and preserving the carbon stored in wood

🔩 Timber-Specific Innovations in DfD

1. RING Connectors – Italian National Research Council (CNR)

Developed by Andrea Polastri at the Institute of BioEconomy:

• RING90C: A single-bolt connector for timber-to-timber, timber-to-concrete, and timber-to-steel joints

• Enables quick and clean disassembly

• Designed for CLT structures with high mechanical performance

• Supports prefabrication and circular construction

2. Disassembled Timber Structures – SENER Group

• Timber’s natural modularity makes it ideal for DfD

• Dismantling preserves structural value and stored carbon

• Promotes reuse in new buildings, reducing landfill waste

• Calls for standardized connections and low-exposure designs to prevent degradation
