Through interviews with twelve hemp-lime households across the UK, France, and the Netherlands, this research explores how long-term occupant experiences influence the adoption of hemp-lime construction. Findings reveal consistently high comfort, minimal maintenance, and strong willingness to recommend the material.

Through an interactive stakeholder workshop at the BBCM 2026 Summit, this research evaluated how builders, consultants, researchers, policymakers, and occupants prioritize evidence for hemp-lime construction. Findings reveal shared priorities around health and thermal performance, role-specific decision patterns, and key evidence gaps that directly inform the next development of the Habitat Atlas platform.

This paper introduces Habitat Atlas, a human-in-the-loop framework that transforms long-term occupant experiences into structured, comparable evidence for biomaterial buildings. Combining phenomenological interviews with researcher-supervised AI-assisted coding, it demonstrates a scalable method for capturing lived performance and supporting evidence-based material decisions.
