Bio-based Prefabricated Construction & Circular Material Innovation

About

BIOCONSTRUCCIONES PREFABRICADAS BRIZNA S.L. is a Spanish architecture, construction and R&D firm specialising in light timber framing systems and prefabricated bio-construction since 2012. We offer expertise in the design and execution of sustainable modular buildings using natural and residual local materials — primarily merino wool as high-performance thermal and acoustic insulation, and timber offcuts integrated back into construction systems.

Our approach directly applies Circular Economy principles by bridging the textile and construction industries: transforming low-value wool by-products from livestock farming into premium building components, while minimising construction waste through the reuse of wood residues.

We collaborate with research institutions (University of Seville, CESEFOR Foundation) and specialised companies (EGOIN), and have demonstrated our systems in rural and low-density environments across Spain and possibility to work in other regions of Europe
