Specifying the right building materials can define the success of your next project.
Linear bricks, with their unique dimensions and contemporary aesthetic, have become a cornerstone of modern architecture. But knowing how to specify linear bricks correctly requires understanding their technical properties, design applications and production characteristics.
This comprehensive guide walks you through everything you need to confidently specify linear brick options for your architectural projects.

Linear bricks, also known as long format bricks, differ significantly from traditional facing bricks in their proportions. These elongated masonry units create striking horizontal lines that bring visual interest to both exterior facades and interior feature walls.
UK Brick's linear collection showcases these distinctive proportions through carefully considered formats. The extended length creates continuity across brickwork, while the slimmer bed height generates a refined, modern look that's particularly suited to contemporary architecture.
Linear bricks feature elongated dimensions that create pronounced horizontal lines in masonry. Their unique proportions deliver a contemporary aesthetic while maintaining the durability and natural material qualities of traditional clay brickwork, making them ideal for modern architectural applications requiring both performance and visual impact.
When specifying linear bricks, several technical requirements deserve attention:
Dimensional accuracy: The production process for long format brick requires precision. Linear brick manufacturing ensures consistent dimensions across batches, critical for achieving clean, uninterrupted lines in your brickwork.
Mortar joint design: Linear formats influence joint proportions. Consider how bed joint thickness affects the overall horizontal emphasis. Thinner joints typically amplify the linear effect.
Structural performance: Despite their slender profile, properly specified linear bricks maintain excellent structural capabilities. Review load-bearing requirements and ensure your specification meets project demands.
Water absorption: Like all quality facing bricks, linear options must demonstrate appropriate water resistance. UK Brick's products undergo rigorous testing to ensure long-term durability.
Linear bricks excel across diverse architectural contexts. Their distinctive profile works beautifully in:
Contemporary residential developments where clean lines define the architectural language
Commercial projects requiring visual differentiation
Renovation work creating striking contrast with existing structures
Interior applications where texture and subtle markings add depth
The clay mixture and production method significantly influence final appearance. UK Brick's waterstruck bricks, for instance, deliver natural surface variations and subtle imperfections that bring character to contemporary facades.
Available colours range across the spectrum, allowing architects to align material specification with broader design intent. These natural materials age gracefully, developing patina while maintaining structural integrity.
Before finalising your linear brick specification, confirm:
1. Format dimensions align with design intent and modular coordination
2. Colour selection complements adjacent building materials
3. Surface finish suits the project requirements
4. Technical performance meets structural and environmental needs
5. Lead times accommodate construction programming
6. Sample panels have been reviewed in situ

Understanding how to specify linear bricks transforms them from a material choice into a design tool. The combination of unique dimensions,durable construction and contemporary aesthetics makes linear formats particularly relevant for today's architectural challenges.
