Facing Bricks Buying Guide: Colours, Textures & Choosing the Right Brick

Facing Bricks Buying Guide for UK Homes and Building Projects

Facing bricks are the visible outer skin of many UK homes, extensions, garden walls and commercial buildings. Unlike engineering bricks, which are selected primarily for technical performance, facing bricks are chosen for a combination of appearance, durability and suitability for the exposed masonry. Colour, texture, manufacturing method, size, mortar and bond all influence the finished result.

With hundreds of combinations available, choosing the right brick can feel more complicated than it needs to be. This guide explains the main types of facing brick, popular colours, UK brick sizes, textures, matching existing brickwork, mortar choices, pack quantities and the practical checks to make before ordering from our facing bricks collection.

What Are Facing Bricks?

Facing bricks are made for visible masonry. Their colour and surface finish are intended to contribute to the building's appearance, while the product also needs appropriate durability and strength for its intended use. They are used on external walls, extensions, porches, garages, garden walls and other exposed brickwork.

Facing bricks should not be confused with common bricks or engineering bricks. Engineering units may have higher specific performance but can have less emphasis on visual consistency. If your project calls for a high-performance engineering unit, compare our engineering bricks separately rather than choosing only by appearance.

Popular Facing Brick Colours

The colour of the brick sets the overall character of a façade. Red facing bricks remain one of the most common choices for traditional UK homes and extensions. Buff and yellow bricks can suit London-style and lighter elevations, while brown and multi-tonal bricks create a warmer, more varied appearance. Grey bricks are popular in contemporary designs and can pair well with anthracite windows, dark roof finishes and modern cladding.

Do not judge colour from a single isolated brick. The final wall is influenced by the full colour blend, mortar, joint profile, bond, daylight and weathering. Where appearance is critical, view a sample panel or completed project in addition to product photography.

Red Facing Bricks

Red bricks range from clean uniform reds to red multis, weathered reds, orange-reds and deep smoked tones. A product such as the Forterra Atherstone Red facing brick provides one live example from the JJ Building Materials range.

When matching an existing red wall, look beyond the basic colour name. Compare undertones, texture, edge profile, size and how much variation appears across a full panel. Two bricks both described as red can look very different once laid.

Grey, Buff and Multi Facing Bricks

Grey facing bricks can create a crisp contemporary façade, while buff and yellow shades are useful for lighter traditional or regional styles. Multi bricks blend several tones in one range and can make new work feel less flat or uniform. They are also useful when an existing wall contains natural colour variation.

If you are matching a building, identify the dominant tone and secondary colours rather than looking for one exact shade. Our brick matching guide for extensions explains a practical process.

Facing Brick Textures

Texture changes how colour is perceived. Smooth bricks reflect light differently from rustic, creased, sanded or weathered finishes. A heavily textured red brick can appear darker and more varied than a smooth brick of a similar clay colour. Texture also affects the character of shadows around mortar joints.

Use product descriptions and close-up images to shortlist, but inspect physical samples where possible. Matching texture is often just as important as matching colour on an extension or repair.

Wirecut Bricks

Wirecut bricks, also called extruded bricks, are formed by extruding clay and cutting it to size with wires. Perforations are common, and the process can produce defined edges and consistent dimensions. Wirecut ranges include smooth, dragfaced, rusticated and other surface treatments, so the manufacturing method does not dictate one appearance.

They are widely used across new-build housing and extensions because there is a huge selection of colours and textures. For a detailed comparison with other types, read our wirecut vs stock vs handmade vs waterstruck guide.

Stock, Handmade and Waterstruck Bricks

Stock bricks and soft-mud products often have softer edges and more traditional character. Handmade-style bricks can show deliberate variation that suits heritage-inspired façades. Waterstruck bricks use water as part of the release process and can have a distinctive smooth yet natural surface character.

None of these types is automatically better. The best choice depends on the architectural style, required technical performance, budget and whether you are matching existing brickwork.

UK Facing Brick Sizes

A very common UK brick size is approximately 215 x 102.5 x 65mm. Other formats exist, including 73mm-high bricks and manufacturer-specific dimensions. Always confirm the exact product because brick height affects coursing and quantity per square metre.

If you are tying into an existing wall, measure several bricks and several mortar courses. Older brickwork may not use modern standard dimensions. Read our UK facing brick sizes guide for calculation examples.

How Mortar Changes the Look of Facing Bricks

Mortar can account for a significant proportion of the visible wall area, so its colour and joint finish deserve as much attention as the brick. Pale mortar can brighten a dark brick and emphasise individual units. Dark grey mortar can create a more blended contemporary appearance. Buff mortar can complement warmer red, brown and yellow bricks.

Technical mortar specification must come before colour. The masonry designer should consider brick suction, exposure, wall type and required performance. Once the appropriate mortar type is established, colour can be selected within that system. See our brick colours and mortar guide.

Matching Facing Bricks for an Extension

Perfect matching is difficult because existing bricks weather and age. Start by recording brick dimensions, colour blend, texture, manufacturing appearance and mortar. Then compare several candidate bricks against the actual wall in natural daylight.

A close match is often more convincing when mortar colour and joint profile are also matched. Even an excellent brick can stand out if the new mortar is much lighter, darker or differently tooled than the original wall.

Technical Properties to Check

Appearance should never replace technical checks. Review the manufacturer's declared compressive strength, water absorption, durability designation, soluble salts classification, dimensions, configuration and any project-specific requirements. For exposed external masonry, use a brick appropriate to the environment and wall design.

Do not assume all facing bricks have identical performance because they belong to the same brand or colour family. Compare the exact product declaration.

How Many Facing Bricks Do I Need?

For a standard 215 x 102.5 x 65mm brick laid with typical 10mm joints, around 60 bricks per square metre is a common preliminary estimate for a half-brick wall face. Actual requirements depend on size, bond, joints, openings, piers and waste.

Measure the wall, subtract substantial openings, add returns and piers, then include a sensible waste allowance. Pack quantities vary significantly by product, so round the final requirement to a practical number of packs.

Choosing Bricks for a Garden Wall

A garden wall is highly visible and exposed to weather, so choose a facing brick with suitable declared durability for the location. Good coping, foundations, mortar and movement detailing matter as much as brick choice. For freestanding walls, height and wind exposure can also make structural design important.

Choosing Bricks for a New-Build or Extension

For a new façade, you have more freedom to choose colour and texture around the wider design. For an extension, compatibility with the existing building usually becomes the priority. Consider roof colour, windows, doors, render, stone details and paving so the brick does not need to work in isolation.

Brands to Compare

JJ Building Materials offers facing bricks from major manufacturers including Forterra, Ibstock and Wienerberger. Each has broad ranges covering traditional and contemporary colours, wirecut and soft-mud appearances, smooth and textured faces and different pack quantities. Compare individual products rather than assuming one brand is universally best.

Facing Brick Buying Checklist

• Confirm the architectural colour and texture required.
• Check brick dimensions and compatibility with the design.

Facing Bricks FAQs

What is the difference between facing bricks and engineering bricks?

Facing bricks are intended for visible masonry and place more emphasis on appearance. Engineering bricks are selected primarily for high strength and low water absorption.

What is the standard UK facing brick size?

Approximately 215 x 102.5 x 65mm is very common, but other sizes are sold. Check the exact product dimensions.

How many facing bricks are needed per square metre?

Around 60 standard bricks per m² is a common early estimate for one wall face with typical joints, but calculate from actual dimensions for ordering.

Which brick colour is best for an extension?

The best colour is the one that works with the existing wall, including its variation and weathering. Texture, size and mortar are equally important.

Are wirecut bricks good facing bricks?

Yes. Many popular UK facing bricks are wirecut. Suitability depends on the exact product and desired appearance.

Can I mix brick batches?

It is generally better to order enough material together and blend from several packs during laying to distribute normal shade variation.

Do facing bricks need sealing?

Clay facing brickwork is not normally treated with a generic sealer as a default. Follow manufacturer guidance and resolve moisture through proper masonry detailing.

Final Advice

Choose facing bricks as part of the whole elevation, not as an isolated product. Start with technical suitability and dimensions, then compare colour, texture, manufacturing style and mortar. A well-chosen brick and mortar combination can make an extension feel integrated and give a new building a much more considered finish.
