    Our approach

    Made in Lithuania, from frame to panel

    Frames and panels are produced in-house rather than assembled from mixed suppliers. That keeps tolerances consistent, so parts fit on the first attempt and the structure stays square for years.

    Every batch passes factory production control before it is packed — the same process our KIWA EN 1090 certification covers.

    Materials chosen for the long term

    • Galvanized steel structure

      Hot-dip galvanized, powder-coated steel profiles form the frame — chosen for load capacity and corrosion resistance over decades of outdoor use.

    • UV-protected polycarbonate

      Thick multi-wall panels with a UV-protective layer diffuse light evenly and resist yellowing and impact.

    • Practical, modular design

      Components are produced to fixed tolerances so panels, clips and fasteners align on site — and the structure can be extended in modules.

    Certification

    Certified quality, documented.

    Our production is certified to KIWA EN 1090, the European standard for the execution of steel structures, alongside CE marking and ISO 9001 quality management. Certification is how our quality process is verified and recorded — not a label we apply ourselves.

    Packed with purpose

    A shipping crate you keep

    Every greenhouse ships in a protective wooden crate built to survive freight. Once it is unpacked, the crate can be repurposed as a raised garden bed instead of being discarded.

    Long-term ownership

    A 10-year warranty and people who grow, too

    Every structure is covered by a 10-year warranty, and our team is available seven days a week for sizing, siting and assembly questions.
