Lignacite is a UK-based construction materials company that specializes in sustainable concrete blocks. Founded in 1947 and based in Brandon, Suffolk, it operates from two modern plants, with additional production in Nazeing, Essex. From its origins making a single block with cement, sand and recycled wood shavings, the company now offers a range of recycled-content blocks used in high-profile projects and by major housebuilders. Its products have been employed on landmarks and large-scale sites such as The Gherkin, The Shard, the Olympic Stadium, Canary Wharf, and at Heathrow and Stansted airports. Lignacite maintains a focus on in-house R&D to drive sustainability, and it has recently expanded its product line with initiatives like the ECO Range, as well as industry initiatives such as the Fly Over London competition announced in 2026.
