Sloping site pool fence design: sections, levels and retaining walls

On a slope, a plan view is not enough. Sections and levels show whether the fence will work.

Why sections matter on a slope

A plan shows where the fence runs. A section shows what happens to the ground on either side of it. On a sloping site the finished ground level changes along the fence, and the QBCC measures the minimum 1200mm fence height from finished ground level, so the drawings need to show it at the lowest point.

Retaining walls and the barrier

Retaining walls change the ground level beside the pool. Show where the wall meets the fence, and check that the fence height and the gap under the barrier are still right. The QBCC says the gap under the barrier should be 100mm or less, and notes that panels can shift or drop when the ground moves, which can reduce the legal height.

Stepped panels

Glass panels are straight, so the fence steps down the slope in sections. Draw each step in the fence line, and check the height at the downhill end of every panel. Where stairs sit beside the pool, the QBCC says to measure stair-side panels from the tread nosing, at right angles, so the fence stays at least 1200mm high.

What to check on the drawings

1. Finished levels at both ends of each fence section.
2. Sections through the fence at the steepest points.
3. The position of retaining walls, steps and planters near the barrier.
4. Any change of level at the gate.

Working with a designer on a sloping block

Choose a designer who is used to slopes. Jay Francis's building design practice, Francis Design, lists site feasibility and working drawings among its services in Sydney and the Illawarra, where approval rules differ from Queensland, so check the rules for your own state.
