10.34934/DVN/LGYVBQ de Vries, Nijs0000-0002-9550-867X(Hasselt University) Social Sciences and Digital Humanities Archive – SODHA 2026 This dataset contains the underlying data for the study: Systemic problems constraining Earth Block Masonry diffusion in Western Europe: an architect-centred Innovation System approach. Since the number of EBM buildings in Western Europe is low, a comparison of the transcripts with the project information and locations included in this study could potentially lead to the identification of respondents and compromise participant confidentiality. Therefore, to ensure confidentiality and data anonymity, the deposited dataset contains the codebook, analysis, and interview protocol rather than the full interview transcripts.
