Designing a building for disassembly means deciding early how its parts can be accessed, separated and reused or recovered at the end of their service life. The CircularBuild 2026 programme described a practical workshop using product samples and live design scenarios to trace steel from production through disassembly and reuse. Its central lesson applies well beyond steel: circularity has to be built into design, specification and documentation—not left until demolition.
What does design for disassembly mean?
Design for disassembly (DfD) is the practice of anticipating how a building and its components might be taken apart in the future. The aim is to make removal orderly and, where possible, non-destructive. If a component can be removed intact, it may be suitable for reuse as a component; if not, selective dismantling may still allow its materials to be recovered.
This is one part of circular building design. Circularity can also involve extending the useful life of parts, adapting buildings to new needs, recovering materials, reducing reliance on virgin resources and considering harmful substances across the building life cycle. These are intended outcomes, not guarantees: actual reuse depends on condition, documentation, demand, logistics and other project circumstances.
The 2024 chapter by Stella Tsoka and Katerina Tsikaloudaki describes a Scopus-based bibliometric analysis that found more than 3,000 publications on circular economy and buildings since 2008. A narrower search for circular design and buildings returned 36 relevant papers. Those figures report the chapter’s search results, not a current census of the field.

Which design choices make a building easier to take apart?
Choose connections that can be reached and reversed
Accessible mechanical joints are generally easier to undo than glued or welded connections. That does not make mechanical connections right for every application: structural engineering, fire, moisture, acoustic and other performance requirements still govern the choice. Specify connections that meet those requirements while making future inspection and separation practicable where possible.
Keep components independent
When one element can be removed without damaging several others, it is more likely to remain useful. Prefabricated elements, a basic open configuration and separation between building layers can support this independence. Limit finishes or bonded layers that could compromise reuse or recycling, while meeting the building’s performance needs.
Design for access, handling and removal order
A reversible joint is not enough if it is buried, blocked or impossible to handle safely. Plan space for workers and equipment, identify what must be removed first, and consider how components will be moved out. A disassembly plan should show the steps and sequence, machinery and handling space, and intended destination of each component or material.
Document what is there
Future teams need to know what a component is, where it is, how it is connected and what materials or substances it contains. Keep component information and construction details with the project record. Building information modelling (BIM) and material passports are among the digital tools discussed in the 2024 chapter as enablers for circular design; their value depends on maintaining useful, accurate information through the building’s life.
How should disassembly decisions fit into project stages?
The decisions become harder to recover if they are postponed until construction. Tsoka and Tsikaloudaki describe circular choices across three design phases:
| Project phase | Decisions to make |
|---|---|
| Conceptual design | Identify project needs and set circularity objectives, including whether adaptability, future separation or material recovery is a priority. |
| Design development | Develop modularity, prefabrication and disassembly strategies; coordinate components and their connections. |
| Detailed design and documentation | Record the construction details needed for assembly and future disassembly, including connections, access, sequence and component information. |
Specifications and drawings should make the intent actionable: describe the connection, how it can be accessed, what must be removed first and how recovered components are to be identified. Coordination matters too; a detail that is reversible in isolation may be obstructed by another trade’s work or by later finishes.
A practical disassembly checklist for a project team
Use these questions while reviewing a design, specification or construction detail. They synthesize practical guidance; they are not presented as a verbatim CircularBuild workshop handout.
- Access: Can the connection be reached for inspection and removal?
- Separation: Can parts be separated without damaging valuable components?
- Sequence: What has to be removed first, and can the steps be carried out safely?
- Handling: Is there enough space and suitable equipment to move the parts?
- Identification: Are components, connections and relevant material information documented?
- Destination: Who is responsible for recovered materials, and where will they go?
- Performance: Do the proposed joints and details still meet the building’s structural and other performance requirements?
What can disassembly planning achieve—and what can get in the way?
When conditions support it, disassembly planning can help preserve whole components for reuse, recover materials, extend the service life of building parts and reduce reliance on virgin raw materials. The Circular Buildings guidance also identifies lower landfill costs as a potential benefit. None of these results follows automatically from specifying a reversible connection.

Implementation can take more time and coordination than conventional end-of-life planning. It may require space, equipment and trained workers; chemical joints can demand damaging solvent or mechanical operations; and some steel structures can cost more to disassemble than to demolish conventionally. Costs and outcomes depend on the design, site, recovered materials and available routes for reuse or recycling.
For the CircularBuild session, the indexed 2026 programme description framed the workshop around retrofit and new-build scenarios, product samples and the path of steel from production to disassembly and reuse. It said participants would work toward a specification checklist and a project action. The session page now redirects to the 2027 event site, so those details describe the indexed 2026 programme rather than a currently available session page.
