Brick is one of the most enduring building materials in the world, it is celebrated for its durability, charm, and versatility. For centuries, brick has been the material that architects and builders have turned to. In the world of modern architecture, even a traditional material like brick can evolve, and that’s exactly what’s happening with long format bricks, sometimes called ‘linear’ bricks.
The practical performance and durability of brick is undeniable. Architects continue to choose to work with brick not just because of it’s versatility and durability but they also choose it for the beautiful aesthetic that can be achieved with this building product.
At Creative Brick Solutions, we’re passionate about innovation in brickwork. Brick is evolving, and in recent years we’ve noticed more and more architects choose long format bricks for their projects. When architects are working on innovative designs, introducing creative texture, contemporary elegance, and eye-catching visual features, they often specify linear bricks.
In this blog our team explores how brick is changing and why long format bricks are quickly becoming a popular choice with architects. We’ll cover what linear bricks are, how they’re made, what makes them special, and how they can be used to elevate your next building project.
What Are Long Format or Linear Bricks?
Long format bricks differ from standard bricks primarily in their dimensions. While a traditional UK brick might measure 215mm long by 102.5mm wide and 65mm high, linear bricks extend far beyond that in length, sometimes up to 500mm or more.
They typically maintain a thinner profile, often 38mm to 65mm in height, resulting in an elongated, elegant appearance. These unique proportions often result in bricks that create a striking effect, whether used internally or externally.
Sizes vary widely, with some of the most common including:
· Danish Standard: 468mm long × 38mm high
· UK Long Format: 440mm long × 65mm high
· French format: 40mm x 450mm long
· Custom Options: Manufacturers around Europe and beyond offer a wide array of formats between these two ends of the spectrum. This range of choice allows designers and specifiers to play with proportion, scale, rhythm, and texture in ways that they’re simply not able to do with standard brick sizes.
How Are Long Format Bricks Made?
Just like standard bricks, long format bricks can be manufactured using different techniques, each offering distinct finishes and characteristics:
· Stock bricks: are made using traditional moulds. This method often produces softer edges and a slightly irregular surface, adding charm and authenticity. Many long format bricks in this category are hand-made, which adds a sense of individuality and uniqueness to the finished product.
· Wirecut bricks: or extruded bricks are produced by pushing clay through a die and cutting it to length with wires. This process results in crisp edges and a more uniform appearance, this is ideal for modern designs where precision is paramount.
· Waterstruck bricks: use water in the moulding process to produce a smooth, almost silky finish. With the combination of the elongated shape and subtle surface, these bricks create an elegant and sophisticated aesthetic.
Because many long format bricks are hand-made or produced in smaller batches, manufacturers can offer extensive flexibility with textures, colours, and custom shapes. This opens the door to specials, corner pieces, and even curved or radial bricks that can truly transform a project.
The Design Possibilities
One of the most exciting aspects of long format bricks is the vast choice they open up to architects. These bricks can completely change the feel of a facade or interior wall. From creating subtle elegance to bold modernity, they make innovative designs available without compromising on quality materials.
1. Refined Texture and Elegance A long, waterstruck stock brick, such as the 468mm × 38mm Danish format, brings a delicate, refined feel to a wall. The soft finish draws the eye, and the scale offers a sense of elegance and flow. These bricks are particularly well-suited for internal features like staircases, entrance halls, and display walls, where tactile and visual interaction is needed.
2. Bold and Contemporary On the other hand, a 65mm × 440mm extruded brick can create strong, bold lines and dramatic blocks of colour. These bricks can emphasise horizontality or verticality in an impactful way. Often popular in commercial and civic architecture where presence and impact matter.
3. Laying Patterns and Orientation Traditional brick bonds such as stretcher bond or flemish bond can be reimagined when working with linear bricks. Their length naturally exaggerates horizontal lines when laid flat, reminiscent of natural strata or stone formations. This makes them ideal for modern minimalist designs that create long, clean lines.
More experimental applications include vertical stacking, which creates a dramatic, tower-like rhythm, especially when used alongside horizontal bonds. This technique can emphasise the height of columns, really effective in stairwells and atriums. Some projects even mix orientations within the same elevation to create contrast and movement.
Off-Site Fabrication and Cladding Applications
As architectural detailing becomes more complex and sustainability demands grow, off-site fabrication and cladding systems become increasingly valuable. Linear bricks are well-suited to these methods:
· Brick Cladding Systems: Linear bricks can be adhered or mechanically fixed with a selected few systems, which are then installed on site. This reduces installation time and ensures consistent jointing and alignment.
· GRC and Precast Concrete: Linear bricks can be embedded into precast concrete or Glass Reinforced Concrete (GRC) units. This approach allows for innovative soffit and lintel details, sharp corners, and even entire brick-faced panels to be lifted into place with precision.
The hand-made or mould-cast nature of many long bricks means that producing specials such as curved bricks or corner details is not just possible but actively encouraged. Designers can explore truly bespoke geometries and textures that would be prohibitively complex with standard-size units.
Long Format Bricks: Key Considerations
While long format bricks offer a wealth of opportunity, there are a few essential things to keep in mind:
1. Dimensional Tolerance and Consistency Some handmade long bricks, particularly the longest formats, may exhibit slight variations in shape or size. This is not a defect, but is a feature of artisanal production. Extruded options may be preferable for projects where tight tolerances are required. Alternatively, using a random or staggered layout can turn this variation into a design strength.
2. Structural and Laying Challenges Due to their extended length, linear bricks may require additional consideration for structural support and movement joints. The chance of cracking increases if movement isn’t properly accounted for. That’s why it is essential to work closely with structural engineers and experienced bricklayers who are familiar with this material.
3. Cost and Availability There’s no denying it, linear bricks are a premium product. They aren’t mass-market, and their production costs reflect the quality and craftsmanship involved. But they’re also not out of reach. Many bricks that are considered “non-standard” in the UK are widely available in mainland Europe as stock items.
Our team of brick experts can help you source long format bricks that strike the right balance between budget and design intent. For instance, keeping the thinner height while slightly reducing the overall length can preserve a linear aesthetic without stretching the budget.
Sustainability and Beauty
Bricks are among today’s most sustainable building materials, long-lasting, low-maintenance, and recyclable. When you use long format bricks to create a durable but also beautiful and meaningful building, you’re making an even greater environmental contribution. When people love a building, when buildings become a landmark, that inspires pride in the community, it is far more likely to be retained, maintained, and reused in the future. In this way, aesthetics become a form of sustainability.
