An unused patch of yard can become the best-used part of a home. A floating deck gives you that extra outdoor area without fixing a frame to the house.<\/p>\n\n\n\n

The job feels much simpler when you take it one layer at a time. This guide shows you how to build a floating deck, from the first site check to the final board.<\/p>\n\n\n\n

What Is a Floating Deck?<\/h2>\n\n\n\n

A floating deck is a low, freestanding deck that does not rely on a building for support. It usually sits near ground level on deck blocks, adjustable feet or approved footings.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The word \u201cfloating\u201d can confuse. The deck may still need anchors or concrete footings for wind, soil or local building codes. Its main feature is that it has no ledger board fixed to the house.<\/p>\n\n\n\n

A typical build has four layers:<\/p>\n\n\n\n

    \n
  1. Compacted ground and drainage.<\/li>\n\n\n\n
  2. Deck blocks, feet or designed footings.<\/li>\n\n\n\n
  3. Bearers, joists and the deck frame.<\/li>\n\n\n\n
  4. Decking boards, clips and edge trims.<\/li>\n<\/ol>\n\n\n\n

    This format works best for low, simple decks. It may not suit steep land, reactive soil or sites with poor drainage.<\/p>\n\n\n\n

    Is Your Site Suitable for a Floating Deck?<\/h2>\n\n\n\n

    Start with the ground, not the decking colour. The site must carry the deck load and shed water after rain.<\/p>\n\n\n\n

    Walk the deck area after wet weather. Look for soft soil, standing water, washout and buried irrigation. Check door clearances, vents, drains, garden beds and the edge of the deck.<\/p>\n\n\n\n

    On wet sites, treat drainage as part of the build. A moisture-resistant deck board cannot protect a frame sitting in trapped water.<\/p>\n\n\n\n

    Mark the proposed deck area with pegs and string. Place the planned furniture inside it. Allow clear paths around doors, chairs and steps.<\/p>\n\n\n\n

    A rectangle is the best starting point for most projects. It reduces cuts, waste and framing time.<\/p>\n\n\n\n

    Do You Need Approval for a Floating Deck in Australia?<\/h2>\n\n\n\n

    A floating deck is not automatically exempt from approval. Rules vary by state, council, size, height, location and site overlays.<\/p>\n\n\n\n

    Check the current National Construction Code structural provisions<\/a>. Then check your state planning portal and local council rules.<\/p>\n\n\n\n
