A curated editorial platform for architects and designers exploring the frontier of sustainable, bio-based, and innovative building materials.
Editor's Pick
Cross-laminated timber has moved well past load-bearing walls. A new wave of designers is using CLT as a finish material — raw, expressive, and deeply connected to the forests that made it. We explore five projects redefining what wood can mean in contemporary interiors.
New material reviews, project deep-dives, and sustainability reports — every week.
Harvested without felling a single tree, cork is the quiet champion of circular materials. We review Wicanders and Granorte — two Portuguese producers redefining what cork can look like.
Made in Spain from natural lime and graphene, Graphenstone paints purify air, absorb CO₂, and last twice as long as conventional finishes. We test the full range.
Natural linoleum made from linseed oil, rosin, and limestone. Carbon-neutral, self-healing, and growing in popularity among sustainable designers across Europe.
Carbon-negative, hygroscopic, and comfortable to install without PPE — hemp insulation from Knauf NaturBoard is rewriting the rules of passive-house building envelopes.
Both Belgian and German brands promise zero-VOC, plant-based protection for timber. We compare application, durability, colour range, and sustainability credentials side by side.
From Castellón to Copenhagen, Spanish-made terracotta cladding is setting the tone for climate-resilient facades. We visit the solar-powered factory behind some of Europe's most specced tiles.
About Soul Materials
Soul Materials is an independent editorial platform dedicated to sustainable building materials for the architecture and design community. We research, test, and write about bio-based, recycled, and innovative materials — with rigour, clarity, and no greenwashing.
Based in Spain, with eyes on Europe and beyond. We believe the materials we build with are not just technical decisions — they are statements about what we value and what kind of future we are shaping.
