Designed for lighter outdoor spaces
A broad, contemporary deck with a soft coastal finish
Create a striking outdoor entertaining space with Wilderness Black Composite Decking, designed for homeowners wanting a bold architectural appearance without sacrificing the warmth and texture of natural timber. Rather than a flat black finish, Wilderness Black features carefully blended charcoal tones and subtle timber variation, producing a premium contemporary look that feels refined and inviting.
The signature 210mm wide profile creates fewer joins than traditional decking boards, enhancing the spacious feel of your deck while showcasing the realistic timber grain. This oversized board profile has become increasingly popular among architects and designers for luxury residential projects due to its clean, minimalist appearance.
Built using advanced composite technology, Wilderness Black offers all the visual appeal of premium hardwood without the constant maintenance. Unlike traditional timber, it won't require regular sanding, staining or oiling and is resistant to moisture, termites, rot and everyday outdoor exposure.
Its darker colour creates a dramatic contrast against landscaping, greenery and light coloured homes while pairing beautifully with outdoor kitchens, glass balustrades, stone paving and modern architectural features.
