“…One group had to build furniture out of floorboards, and another a micro-house (4m2) based on a batch of cut-offs from our case study [35]. Other researchers identified a loss of up to 46% of the volume that will be recycled or recovered [44]. More recent work on the evaluation of timber purchase with the aim of up-cycling confirms these tendencies towards a range between 30 and 50% of loss in the reclamation of timber members produced before the 1950s, mostly not standardised.…”

France's current 'wood wastes' management seems inefficient in settling on a durable reclaimed timber branch that would support reuse practices in architecture. We assume that there is a set of 'values' attached to timber members that should be revealed to estimate their market value better. Through the literature, we observe that the economy of a deconstruction project used to be considered significant, while embodied carbon is nowadays of major concern. Moreover, as Circular Economy and Cascading concept emerged, the meaning of durability has decreased in favour of reversibility that could guarantee a flow of material circulation. The problem is that these ideas involve probable rebound effects due to energy engaged in transportation and the transformation of reclaimed resources. Our reflection comes from a field study experience where we participated in the reuse process of timber members deconstructed from a textile mill. We observed that the lack of economy and the lack of 'values' identification resulted in depreciating the operation's efficiency, whose initial objective was to maximise the extraction and diffusion of reusable elements as much as feasible. Our research focuses on construction materials and massive structural timber members, which still seem challenging to reintegrate into new buildings.

“…The type of connection used between building parts will determine whether or not it can be successfully deconstructed and reused. The use of reversible connectors facilitates the assembly and disassembly and increases the reusability of timber building parts (Al Shamaa and Saleh, 2021; Klinge, 2019a, Akinade et al , 2017). In the case of timber-based buildings, these connections can be realized through carpentry connections that can be assembled, disassembled and reassembled several times without impacting the characteristics and performance of the timber elements in the different layers of the building (Klinge, 2019a).…”

“…The use of reversible connectors facilitates the assembly and disassembly and increases the reusability of timber building parts (Al Shamaa and Saleh, 2021; Klinge, 2019a, Akinade et al , 2017). In the case of timber-based buildings, these connections can be realized through carpentry connections that can be assembled, disassembled and reassembled several times without impacting the characteristics and performance of the timber elements in the different layers of the building (Klinge, 2019a). Two key criteria for designing connections that can be disassembled while maintaining the integrity of all elements are as follows: avoid interpenetration of connectors with components; and adopt dry-jointing techniques in preference to chemical jointing (Morgan and Stevenson, 2005).…”

“…dismantled elements and connectors) in new buildings. As such, it could be named reversible construction, reversible building design or reversible architecture (Arisya and Suryantini, 2021; Dams et al , 2021; Fatourou-Sipsi and Symeonidou, 2021; Viscuso, 2021; Akbarieh et al , 2020; Klinge et al , 2019a). Up to this point, both deconstruction and disassembly are listed as strategies, meaning that deconstruction refers to the selective, systematic dismantling of building parts belonging to a building neither designed nor built for disassembly; while on the other hand, a disassembly activity implies the total dismantling of each building part in a building conceived and constructed for future disassembly and reuse.…”

Purpose The reuse of timber building parts, when designing new buildings, has become a topic of increasing discussion as a proposed circular solution in support of sustainable development goals. Designers face the difficulty of identifying and applying different design strategies for reuse due to multiple definitions, which are used interchangeably. The purpose of this study is to propose a taxonomy to define the relationships between various concepts and practices that comprise the relevant strategies for reuse, notably design for disassembly (DfD) and design for adaptability (DfA). Design/methodology/approach Literature reviews were conducted based on research publications over the previous 12 years and located through the Web of Science and Scopus. Findings A taxonomy for the design process grounded on two strategies for reuse is presented: DfD and DfA. Based on previous work, the taxonomy aims to build a vocabulary of definitions in DfD and DfA to support other researchers and practitioners working in the field. Research limitations/implications The research is limited to the design phase of timber-based buildings. It does not take into account the other phases of the construction process, neither other kind of construction methods. Practical implications The application of the taxonomy can facilitate communication between different actors and provide a way for building product manufacturers to demonstrate their reuse credentials, enabling them to produce and promote compliant products and thereby support design for reuse strategies. Social implications This paper could contribute to a closer collaboration of all stakeholders involved in the building process since the very early phases of the conceptual design. Originality/value This paper contributes a comprehensive taxonomy to support the deployment of circular reuse strategies and assist designers and other stakeholders from the earliest of phases in the building’s life cycle. The proposed definition framework provided by the taxonomy resolves the longstanding lack of a supporting vocabulary for reuse and can be used as a reference for researchers and practitioners working with the DfD and DfA.
