Public Sector

Our versatile range of concrete blocks supports public sector buildings across the country, from schools and hospitals to high-security facilities and landmark projects such as Salisbury Square – the new City of London Law Courts and Police Headquarters.

Supporting Public Sector Projects That Create Lasting Impact

For decades, Lignacite has partnered with the public sector to create buildings that strengthen communities and enhance public wellbeing.

From new schools and school extensions to prisons and landmark projects like the under-construction Salisbury Square in London – set to house the City of London Law Courts and Police Headquarters – our blocks form the foundation for spaces that keep people safe, healthy, educated and thriving.

Lignacite is proud to support projects that make a lasting impact on the places where we live, learn and work.

Commonly Used Products

From modern schools to high-security prisons and mixed-use, multi-storey developments in the capital, Lignacite blocks provide the strength and durability public sector projects demand.

For these buildings, developers typically choose:

Medium-dense Lignacite blocks – available as Paint Grade or Fair Face, ideal for high-quality internal walls.
Lignacrete dense blocks – engineered for strong, reliable foundations.
Lignacite ECO Range blocks – containing up to 70% recycled content and 70% less embodied carbon, perfect for lower-carbon projects with strict BREEAM targets.

Whatever the project, Lignacite has the right blocks for the job – helping public sector buildings deliver safety, quality and longevity, serving communities for generations.
