Water Garden Decking: Design, Construction, and Finishing Touches

Decking Over Water: Extending Your Living Space

Decking hides pond edges or creates landing platforms. Well-built, it's attractive and functional. Large pools: extend over water for relaxation among aquatic life.

Construction Principles

Over-water decking must be tasteful, not dominant. For most pools, narrow strip along edge (like expanded causeway) with supports in surrounding ground, not pool. Most effective just above water surface—reflection subtle, water running underneath looks better than dry land.

Hardwood is best: tough, weather-resistant, mellows to silvery brown. Narrow boards (~10cm/4in) ideal. Incorporate 1–2 neat openings for plants to grow through—links deck to landscape. Use hardy plants.

If extending into pool: proper foundations. Same as bridges. Timber uprights ≥10cm (4in) square: set in large concrete blocks or dropped into pipes in concrete (causeway method). Strong posts for landward side too. All uprights vertical, tops level. Bolt horizontal bearers, screw boards with ~1cm (3/8in) gaps for drainage and aesthetics.

Finishing for Safety and Function

Over-water decking often ends in a feature platform (circular/octagonal) for sitting. Avoid extensive rails—they ruin beauty. But young children = mandatory rails (even in shallow water). Remove when kids understand dangers.

Without children: low kick-board (unobtrusive, helps wheelchair access). Upright at landward end as handhold for less agile; doubles as mooring post if a small boat is featured.
