Fluted blocks and bricks are fast becoming a favourite among architects and designers, and it’s easy to see why. A great example of this is Threefold Architecture’s recent project, which has earned them a finalist spot in the Best Design Awards for Workplace Environments (up to 200sqm)

Their studio, located in Sydenham, is a masterclass in thoughtful design—transforming a former warehouse into a modern, welcoming workspace. 

The shell of this transformation is the clever use of Viblock’s fluted masonry blocks, which add texture and depth to the building’s exterior. 

These blocks, combined with cedar and corten steel, create a façade that is both contemporary and warm, perfectly reflecting the balance of industrial elements with a homely touch. This project beautifully illustrates the versatility of fluted masonry in modern architecture.

Why Fluted Masonry is Gaining Popularity 

Fluted blocks are not just about aesthetic appeal—they also offer a host of practical benefits that make them an excellent choice for a variety of projects. The textured surface of fluted blocks creates a striking visual effect, adding dimension to both interiors and exteriors. Whether used for a dramatic feature wall or a building façade, these blocks provide a distinct visual flow to any structure. 

In addition to their aesthetic appeal, Viblock’s fluted blocks are made from concrete, meaning they come with significant performance advantages. They are non-combustible, provide excellent thermal mass, and are durable enough to withstand the elements, making them ideal for both residential and commercial applications​​.

20 series blocks and why they are used

Above the 20 series in action on exterior in an Architectural build in the Bannockburn hills, being a stand alone product the structural fluted block is more typically used for landcaping, foundation or internal feature walls due to its structural properties.

The images below showcase typical uses for landscaping and feature walls, combining fluted brick and block in Timaru. Note that the landscaping walls have a different profile from the house, which can work when not combined directly on top of each other.

  • The Practical Benefits of Fluted Blocks 
  • The appeal of fluted masonry goes beyond just its good looks. These blocks provide several functional benefits that make them a sound investment for any building project. 
  • Fire Resistance: Made from concrete, fluted blocks are non-combustible, offering peace of mind in both residential and commercial settings. This makes them particularly suited for use around fireplaces or in outdoor kitchens. 
  • Thermal Mass: Concrete has a natural ability to store heat, helping to regulate indoor temperatures and potentially lowering energy costs in the process. 
  • Low Maintenance: Fluted blocks require very little upkeep, making them a practical and durable choice for both exterior and interior applications​. 
  • Getting the Best Results with Fluted Masonry 
  • For architects and designers, selecting the right finish is key to achieving the desired effect. Viblock Bricks offers a wide range of colours and finishes to help tailor the aesthetic to each project’s requirements. Whether you’re looking for a sleek, honed finish or a more textured, rugged surface, there’s a block to suit every style.  
  • In addition to their design flexibility, Viblock’s fluted blocks are locally manufactured in New Zealand, ensuring consistent quality and prompt delivery times. This local production also supports a more sustainable supply chain, another factor that is becoming increasingly important in modern architectural practices​.
