The SPARK Platform Fire Hearth is part of the Slabs By Design architectural concrete collection, designed to create a striking base for modern fireplaces.

Each hearth is handcrafted using high-performance concrete and reinforced with an internal steel support frame to ensure structural integrity and long-term durability.

The platform design provides a clean and minimal appearance while delivering the strength required to support heavy fireplace units.

Every hearth is produced to order and finished by hand, giving each piece a unique concrete character.

The Sheet – The ultimate in “less is more. ” The Sheet is a slim, architectural slab designed to sit flush or near-flush with your flooring. It provides the necessary thermal protection and floor coverage required by safety standards without interrupting the flow of your space.
The Shelf – For those who want a slight elevation, the Shelf profile raises the fire onto a solid concrete platform. This added thickness creates a subtle but deliberate boundary, defining the fireplace zone and giving the firebox a more substantial presence in the room.
The Platform – The flagship of the SPARK range. Standing 300mm high, the Platform elevates your fire to a more comfortable viewing height, making it the undeniable feature of the space. It features a refined 10mm shadow line around the base, creating a sophisticated “floating” effect that lightens the visual weight of the concrete while maintaining its solid, sculptural feel

If Required For A Timber Style Fire That Will Sit Directly On The Hearth

  • Cutout in the top of the concrete fire hearth the same size as the base of the selected fire
  • Welded steel tube construction subframe if required in the Platform range
  • Bolted into the underside cavity of the concrete hearth
  • Heat proof fibre cement panel fitted to the top of the steel frame
  • 5mm steel sheet fixed to the top of the FC Sheeting

  • Fire to be installed by a qualified tradesperson
  • Base of fire to sit evenly on the steel sheet
  • 12 month structural warranty on the concrete
  • Concrete is stain resistant – harsh chemicals when left on the concrete surface may affect the sealer coating
  • Due to expansion and contraction of the concrete as a result of heat, micro cracks may appear which are generally not structural in nature and are normal in concrete
  • All dimensions provided are approximate due to the nature of this product. Slight variations may occur in sizes, colour and finish due to the hand-made nature of the product
  • Placement of the cutout will depend on the selected fire, walls and floor materials used
