Materials
A material earns its place through use, origin, ageing and evidence — not through a sustainability adjective.
Origin before adjective
The House should know what a strategic material is, where it came from, who processed it and which evidence supports any claim made about it. “Premium”, “responsible” or “sustainable” is not a substitute for origin information.
2030 traceability target
By 2030, the House aims for strategic materials used in permanent products to have documented origin, supplier traceability and an appropriate sourcing standard or evidence record. The target remains a target until measured results exist.
Material approval
A material should be reviewed for intended use, ageing, repair, process impacts, restricted substances, sourcing risk, consistency and whether the House can explain why it was chosen. A certificate may support approval but does not replace judgement.
Recycled and alternative content
Recycled, bio-based or alternative content should be stated by verified percentage and by component where relevant. The House should avoid implying that a small recycled element makes an entire object “circular”.
Chemical and process risk
Wet processing, dyeing, finishing, tanning, coatings and adhesives can carry material water, chemistry and worker risks. Supplier evidence and applicable restricted-substance requirements should be defined before production, not after a claim appears on the website.
Archive and evidence
Material decisions should leave a record: supplier, batch or lot where relevant, specification, tests, certificates, claim approvals and later repair observations. Over time this archive should improve product decisions rather than exist only for reporting.
