José Mendoza, MSc Architect & founder of Brizna SL, specializes in light timber framing, bio-construction & prefabrication since 2012, using natural materials like merino wool insulation aligned with circular economy principles.

My organisation

We are an architecture, urbanism and habitat construction firm committed to a healthy lifestyle in harmony with our environment. We design and build using our own Prefabricated Bio-Construction systems, integrating architecture, construction and R&D under one roof. We serve our clients across all scales — from domestic to territorial — whether public or private, and our products are available to any company in the sector. At the core of our approach lies the application of Circular Economy principles, both in the construction industry and in the textile sector. We firmly believe that local and residual materials hold untapped potential to generate innovative, high-value products that benefit multiple industries simultaneously. A key example of this is our use of merino wool — a material traditionally linked to the textile industry — as a high-performance natural insulation system in our prefabricated construction solutions. By doing so, we create a direct bridge between the textile and construction sectors: wool that might otherwise be considered a low-value or residual by-product of livestock farming is transformed into a premium building material, improving thermal and acoustic performance while reducing dependence on synthetic, fossil-fuel-derived insulation products. Similarly, we work with timber offcuts and wood residues generated during prefabrication and industrial processes. Rather than treating these as waste, we integrate them back into our construction systems as structural or finishing components, extending the life cycle of the material and significantly reducing construction waste. This dual approach — rooted in the use of local, natural and residual materials — positions BIOCONSTRUCCIONES PREFABRICADAS BRIZNA S.L. at the intersection of sustainable construction and industrial symbiosis, contributing to a more regenerative, resilient and circular built environment.

About me

Master Architect, has been working with light timber framing systems since 2012. His experience in this field has been key to the development and application of innovative techniques in bio-construction. In 2023, he founded the company with the aim of responding to the growing demand for sustainable and distinctive construction solutions. His vision has been instrumental in introducing materials such as merino wool as insulation, an element that significantly improves the thermal efficiency of construction systems.

His knowledge of prefabrication techniques has been further enriched through his collaboration with the CESEFOR Foundation and specialised companies such as EGOIN, which has helped to improve processes and efficiency in modular prefabricated construction.

José Mendoza Milara has led various innovative projects, as described in section "2.2. Knowledge of the state of the art and current technology", in the field of sustainable architecture and bio-construction, integrating construction solutions based on respect for the environment and energy efficiency. Some of the most notable projects he has worked on include:

  • Sustainable modular housing with merino wool – Development of a prefabricated construction system that optimises structure, thermal and acoustic insulation, and fire resistance using natural materials, in Barrado.

  • Light timber framing structures in rural environments – Design and execution of resilient, energy-efficient buildings in low-density population areas, including a hostel in Carmona.

  • Collaboration with CESEFOR on wood industrialisation projects – Implementation of optimisation processes in modular construction using renewable resources.

  • Development of passive housing prototypes – Application of energy efficiency strategies to minimise energy consumption in buildings, in collaboration with the University of Seville research group "Transhumancias: Habitat, Health, Heritage, Technology and Art".

  • Integration of traditional construction techniques with prefabrication – Combination of historical construction methods with technological innovations to improve sustainability and speed of housing execution. Restoration of shelters such as the mato en el Risco, in the La Siberia Biosphere Reserve.

His work has been featured in specialised bio-construction publications, where his advances in the application of prefabricated systems and his contribution to the development of architectural models aligned with circular economy principles have been highlighted. His experience with local materials and his focus on optimising construction processes have been key to the growth of BIOCONSTRUCCIONES PREFABRICADAS BRIZNA S.L., establishing it as a benchmark company in the bio-construction sector.
