Eco Buildings Group Albania Completes Independent EN, ISO and BS Standard Testing for Its GFRG Structural Wall System, Establishing Platform for UK Expansion

Eco Buildings Group plc, a UK-listed modular construction company, is pleased to announce that its Albanian subsidiary, Eco Buildings Group Albania, has successfully completed a comprehensive and independent programme of testing in accordance with European (EN) and International (ISO) standards, each is equivalent to British Standards (BS). The results as set out in the table below confirm the strong performance of the Company's proprietary Glass Fibre Reinforced Gypsum (GFRG) wall system, the structural core of Eco Buildings' low-carbon, high-speed modular housing technology.

Independently Conducted and Verified

The testing was conducted independently by Altea Geostudio, an accredited European laboratory certified to international quality standards (including TÜV Austria accreditation). The laboratory performed all assessments under EN and ISO methodologies recognised as equivalent to British Standards (BS) within current UK and EU construction-product frameworks.

The testing by Altea awarded compliance with the following standards:

This independent laboratory testing demonstrates that Eco Buildings' GFRG walls meet or exceed the thresholds required for structural integrity, safety, durability and environmental efficiency, fully aligned with British Standards equivalence.

Raising the Bar in Modular Construction

The Directors believe that few companies in the modular-construction sector have undertaken such a broad, independently verified testing programme across all EN, ISO and BS-equivalent categories. This depth of validation places Eco Buildings among the most technically proven and transparent producers of modular systems in Europe, reinforcing credibility with regulators, partners and institutional investors; and uniquely utilizing GFRG core material.

Because EN and BS frameworks are harmonised, Eco Buildings can present a single recognised dataset across both EU and UK jurisdictions, reducing approval timelines and ensuring compliance with EU CPR and UKCA regimes. This provides a competitive advantage as governments and developers increasingly prioritise pre-validated, sustainable construction solutions.

Strategic Importance and UK Market Readiness

Completion of this independent testing provides a robust technical foundation for Eco Buildings' international expansion and directly supports its entry into the UK modular-housing market. With performance verified to EN and ISO standards equivalent to BS, Eco Buildings can now engage with UK developers, housing associations and local authorities confident that its system satisfies domestic compliance and performance benchmarks.

The Company is advancing plans for its first UK modular production facility, delivering sustainable, factory-built homes consistent with national Net-Zero and affordable housing objectives.

Executive Comment

Dr Etrur Albani, Executive Vice-Chairman of Eco Buildings Group plc, commented:

"Completion of this independent EN and ISO testing, equivalent to British Standards, represents a major technical milestone for Eco Buildings. These standards are the universal measure of quality, safety and sustainability in construction, and a limited number of companies in our sector have been tested to this level. It confirms that our GFRG system consistently delivers excellence in strength, fire safety, thermal and acoustic performance. With this foundation, Eco Buildings is ideally positioned to scale across Europe and to bring our proven modular-housing technology to the UK market."
