Recycled bricks: The secret to architectural beauty and a lower carbon footprint

An often overlooked and underestimated sustainable building material is recycled bricks. 

“Every recycled brick has a history and unique character,” shares The Brick Pit’s Ohad Fleiderman. “A secondhand brick, compared to one that imitates the look of a recycled brick, is much more authentic and beautiful. Using reclaimed bricks can cost less, and it’s so much better for the environment in terms of lowering embodied carbon and associated carbon emissions.”

Each day, The Brick Pit recovers thousands of bricks from demolition sites across Sydney and beyond, carefully cleaning and sorting every piece by colour and condition. It’s a process that would often be unachievable for professionals working on individual projects, but The Brick Pit takes care of the hard work – delivering ready-to-use, curated bricks directly to site.

Where choosing sustainably often comes with a premium, recycled bricks are a rare exception: they’re more affordable, better for the environment, and provide an aesthetic that can’t be truly replicated. 

“Bricks don’t need to be bought new. Why not reuse what’s already available?” says Clinton Cole, Managing Director of CplusC Architects + Builders. “The future building blocks of our built environment are already here, and they’re ready for another few centuries of life. Plus, fancy new bricks can be about 100 per cent more expensive.”

The Brick Pit’s Feature Blends are hand-curated groupings of recycled bricks, carefully selected to deliver the right balance of tones and textures for specific projects. Rather than leaving the final look to chance, the team collaborates with architects and clients to create custom formulas, ensuring the right balance.

“Most customers don’t want just one colour – they want a blend that looks random, but it’s not random. They choose the percentage of each colour, and we make sure every layer of every pallet matches that formula. Even for a 20,000-brick project, every pallet is consistent,” says Ohad.  

“This way, the bricklayer just picks from the pallet and the wall looks beautifully random, but it’s exactly what the customer asked for. We don’t include colours they don’t want, or too much of one tone. It’s a system that gives customers confidence – they know exactly what they’re getting.”

Combo Bricks can also provide huge cost savings: if there is no colour preference, or the bricks will be used in a part of the build where they won’t be seen, more cost-effective bricks can be specified.

Beyond sustainability and design versatility, recycled bricks offer proven performance. Many have been used for decades – sometimes even centuries – in Australia's harshest conditions. 

“Some of the dry-pressed bricks we use might have been on the edge of a cliff facing the Pacific, with wind and moisture. They’re 100 years old and they still look new. They’ve stood the test of time and are much stronger than today’s bricks made with holes inside,” says Ohad. 

Specifying recycled bricks certainly isn’t a compromise or an option to be seen as costly and complicated. With The Brick Pit’s carefully curated Feature Blends, architects can achieve unique designs with confidence, knowing that each brick contributes to reducing embodied carbon and supporting the circular economy. 

Designing with circularity in mind has become a responsibility for architects across Australia, and recycled bricks prove that sustainability, performance and architectural beauty can coexist – that building responsibly doesn’t need to be met with limitations.
