The Build
Inside the install
Every angle of a pool built on a suspended slab, with the infinity edge running into a hidden stainless trough beneath the deck.
The Project
Engineering a pool to sit at house level, with the water disappearing toward the bay
This infinity-edge pool and spa combo with a wader, built on St Andrews Beach in Rye, is one of the most technically demanding installations we’ve completed on the Mornington Peninsula. Knowledge, design and engineering all came together on this site.
The brief
Pool at house level — not buried in a hole — so the view stays the centrepiece.
The client wanted to enjoy the view with the pool, not look down into it. That meant building a suspended slab to bring the pool up to deck height, with custom-positioned holes for the in-floor cleaning heads designed into the slab itself.
The drop edge
A custom drop-edge built into the pool shell along two sides, feeding hidden water tanks beneath the deck.
The negative edge required us to manufacture the swimming pool shell with a ‘drop edge’ custom built into the pool along two sides. The water overflows into a stainless trough that’s caught by two large tanks under the suspended slab — invisible plumbing, silent operation.
The colour
Pearl Bi-luminite — the look of a fully-tiled pool without the maintenance of one.
They loved the look of fully tiled pools but didn’t want to manage that surface. They’d owned an old concrete pool before and had struggled with the scum line — especially over a negative edge. Pearl gives the bright, light, fully-finished look without the maintenance penalty. And the suspended slab was designed for a lighter pool than concrete would have allowed.
Three water zones, one calm look
Pool, spa and wader — each with a job, none competing visually.
Three functioning water features in one zone could easily have looked busy. The client wanted minimalist clean lines and got them: lap pool for swimming, spa for relaxation, and a 3m wader for the small grandchildren — all reading as one continuous architectural gesture toward the bay.

Why Compass For Complex Coastal Builds
Four reasons St Andrews Beach worked
Suspended slabs, drop-edge shells and coastal exposure are the difference between a pool that looks the part and one that performs for 30 years.
Suspended-slab engineering
Bringing the pool to deck height demands a slab strong enough to hold the pool, the water and the people — with cleaning-head holes positioned to the millimetre during pour. Done wrong, you don’t get a second chance.
Custom drop-edge shells
For a two-sided infinity edge to work cleanly, the drop has to be built into the pool itself — not assembled on site from spillway trim. Our shells are manufactured with the edge engineered into the mould.
Pearl Bi-luminite
Mineral-rich ceramic colour that delivers the look of a fully tiled pool without the maintenance penalty of grout lines or scum-line build-up. Perfect for negative-edge installs where water clarity matters.
Multi-zone integration
Pool + spa + wader as one architectural composition. We design the three together so the visual flow stays calm even though the use cases are different: laps, lounging, kids.
