DIY DeckCell Low-profile Decking Subframe

The DIY DeckCell Subframe System by NexGEN is the world’s most accessible modular decking solution — if you can build with Lego, you can build with DeckCell. Designed for simplicity, strength, and longevity, this innovative system replaces traditional timber or steel subframes with durable, rot-proof panels that will never rust, warp, or degrade. With an ultra-low 50mm profile, it’s perfect for creating decks over concrete, pavers, tiles, compacted sand, or waterproof membranes.

DeckCell’s clever modular design makes installation fast and tool-free — no need for welders, specialist equipment, or professional trades. Simply click the panels together, feed through NexGEN Poly Joists, and you’re ready to lay your composite decking boards. Fully compatible with NexGEN’s hidden fastening system, DIY DeckCell is ideal for anyone looking to save time, money, and effort while achieving a professional-quality finish that’s built to last.
