Designing an infinity pool in Melbourne

An infinity pool is often described as a feature, but that undersells what it actually does. The infinity edge removes the visual barrier between the pool and the outlook beyond it, so the water appears to run to the edge of the view and stop at nothing. It is less about the pool drawing attention to itself and more about the pool connecting you to everything around it.

That effect is precise. It depends on engineering and millimetre-level control, which is why an infinity edge is a design decision to resolve early, not a finish to add at the end.

What an infinity edge actually does

A standard pool has a coping edge that sits above the waterline and reads as a boundary. An infinity edge works the opposite way. On one or more sides, the water is held exactly level with a wall so it spills gently over the top, which removes the visible edge and lets the surface appear to meet the horizon, a garden or the outlook beyond.

The water that flows over is caught in a hidden tank below and returned to the pool continuously. None of that mechanism is visible. What you see is a still sheet of water with no apparent boundary, which is the entire point.

Why an infinity edge needs concrete and precision

The illusion only holds if the spill edge is dead level along its full length. A few millimetres of variation and the effect breaks, with water sheeting unevenly or the edge reading as a line again. This is where concrete earns its place. Because a concrete pool is formed in place rather than delivered as a fixed shell, the wall can be engineered and finished to the exact level the effect demands, on a site that is rarely flat to begin with.

It also takes a team that controls the whole build to get there. The structure, the edge, the balance tank and the finish all have to be resolved together, which is far harder to guarantee when a job is handed between subcontractors. You can read more about how we approach this on our concrete pools page.

The Kilmore project

Our Kilmore project shows how far the idea can be taken. It is a curved concrete pool and spa with an infinity edge engineered to carry the water to the window ledge of the home, so the water appears to meet your feet from inside the house. It turns the pool into part of the architecture and the outlook into part of the living space, the kind of resort-style connection that is hard to achieve and unmistakable when it works.

The Kilmore build sits at the top of the bracket we take on, and it is the clearest example of what an infinity edge can do when the pool and the home are designed to speak to each other. You can see it on our Kilmore project page.

Using the edge to frame a view

An infinity edge is at its strongest where there is something to connect to. On our Kilsyth project, the infinity edge is used as a framing element for the surrounding landscape, strengthening the visual link between the pool and the outlook so the water sits lightly in its setting rather than dominating it. You can see it on our Kilsyth project page.

A controlled, in-house build matters most here

Of every pool type we build, an infinity edge leaves the least room for error. The level tolerances are unforgiving and the hidden mechanism has to be right the first time. That is exactly why we deliver these projects entirely in-house, one at a time. A single team carrying the project from planning through to completion is what keeps the edge true and the effect intact.

It is also why an infinity edge is worth resolving as part of the overall design rather than treating as an upgrade. The slope, the outlook, the structure and the edge all inform one another.

A considered investment in connection

An infinity edge is not for every site, and that is part of what makes it special. Where the outlook is there to be framed, it is one of the most considered things you can do with water, drawing the view into the home and the home into the landscape. If you are weighing up whether your site suits one, you are welcome to start a conversation with us.

Frequently asked questions

How does an infinity edge pool work?

On one or more sides, the water is held exactly level with a wall so it spills over the top into a hidden balance tank below, which returns it to the pool. This removes the visible edge so the water appears to meet the view beyond.

Do you need a view or a slope for an infinity edge?

It helps. An infinity edge is at its best where there is an outlook, a fall in the land or a strong view to spill toward. On a flat site with no outlook, a different design will usually serve the home better.

Why does an infinity edge need a concrete pool?

The effect relies on the spill edge being perfectly level along its full length, which a formed-in-place concrete pool can be engineered and finished to achieve. A pre-moulded shell cannot be built to those tolerances on a real site.
