Infinity pools, also known as wet-edge, vanishing edge, or negative edge pools, are a design feature where one or more edges of the pool are at the same level as the water. This allows water to flow over the edge into a catch basin below, creating a seamless visual effect, particularly effective on sloped blocks or properties with expansive views. In Brisbane, where many homes are built on hilly terrain or overlook the river and city, infinity pools can significantly enhance a property's aesthetic and value. They are often chosen for their luxurious appearance and the way they integrate with the surrounding landscape.
Building an infinity pool in Brisbane involves several key stages, typically taking 12 to 20 weeks from excavation to completion, depending on complexity and weather. The process begins with detailed design and engineering to account for the unique hydraulic requirements of the vanishing edge. Excavation then prepares the site, often requiring more extensive earthworks due to the need for a lower catch basin. Concrete shell construction follows, with careful attention to waterproofing and the precise levelling of the infinity edge. Finally, plumbing, tiling, coping, and landscaping complete the project. Throughout this, council approvals are crucial, as Brisbane City Council requires building approval for all swimming pools and fences, and planning approval may be needed depending on your property's zone or if it falls within a flood or heritage overlay.
The cost of an infinity pool in Brisbane varies significantly based on several factors. The primary drivers are the size and depth of the pool, the number of vanishing edges, and the complexity of the site. Properties with difficult access, steep slopes, or challenging ground conditions (such as rock or reactive clay) will incur higher excavation and engineering costs. Material choices for tiling, coping, and the pool interior also influence the final price. Beyond the pool itself, consider costs for pool fencing, landscaping, and any retaining walls, especially if your property is on a slope or in an area with a landslide overlay. Overlooking these additional elements can lead to unexpected expenses later in the project.
Technician insight
In Brisbane, the thing that catches most people out with Infinity Pools is the site preparation, especially on sloping blocks common in areas like The Gap or Camp Hill. The engineering for the cantilevered edge and the need for a separate catch basin often mean more extensive and costly excavation and retaining wall work than anticipated, particularly if you hit rock or have reactive clay. It's crucial to have a thorough geotechnical survey done early.
Infinity Pool on a Sloping Block in Kenmore Hills
A homeowner in Kenmore Hills wanted an infinity pool overlooking the Cubberla Creek catchment. The sloping block required significant earthworks and a substantial retaining wall. We found the soil was highly reactive clay, necessitating a more robust foundation. By adjusting the pool's position slightly and using a stepped retaining wall design, we achieved the desired vanishing edge effect while managing the site's challenges and ensuring structural integrity.
Infinity Pools Services We Offer
✓Single Vanishing Edge Pool
This design features one edge where the water appears to spill into the horizon, ideal for properties with a single dominant view, often seen in hillside homes in areas like Chapel Hill or Kenmore.
✓Multi-Edge Infinity Pool
For panoramic views, a pool with two or more vanishing edges can be designed, creating a dramatic effect from multiple angles, suitable for larger, elevated blocks across Brisbane.
✓Infinity Plunge Pool
A compact infinity pool designed for smaller backyards or courtyards, offering the visual drama of a vanishing edge within a limited footprint, popular in inner-city suburbs like Paddington or Bulimba.
✓Infinity Spa Integration
Combining an infinity edge with an integrated spa, allowing for a seamless water feature that offers both swimming and relaxation, often chosen for luxury homes in areas like Ascot or Hamilton.
✓Perimeter Overflow Pool
Similar to an infinity edge but with water overflowing on all sides, creating a mirror-like surface. This design works well on flat blocks where a strong architectural statement is desired.
How it works
- 1
Initial Consultation and Site Assessment
A preliminary discussion about your vision, budget, and a thorough assessment of your Brisbane property. This includes evaluating site access, soil conditions, gradient, and potential council overlay considerations like flood or heritage zones, particularly important for areas around Enoggera Creek or Ithaca Creek.
- 2
Design and Engineering
Detailed architectural and structural plans are developed, incorporating the infinity edge hydraulics and ensuring compliance with Queensland Building and Construction Commission (QBCC) standards and Australian Standard AS 1926 for pool safety. This stage includes preparing documentation for Brisbane City Council building and planning approvals.
- 3
Council Approvals and Permits
All necessary applications are submitted to Brisbane City Council for building approval of the pool and fence. If your property has specific overlays (e.g., Flood, Landslide, Waterway corridor), planning approval may also be required, which can extend the timeline.
- 4
Construction and Installation
Once approvals are in place, excavation begins, followed by the concrete shell construction, plumbing, and precise levelling of the infinity edge. This stage also includes the installation of filtration systems, interior finishes, coping, and fencing to meet safety regulations.
- 5
Handover and Pool Safety Certificate
Upon completion, a final inspection is conducted. A Pool Safety Certificate is obtained and registered with the Queensland pool safety register, confirming the pool and fence comply with AS 1926. You will receive guidance on operating and maintaining your new infinity pool.
Pricing
Infinity pools typically start from $80,000 to $150,000 for a basic design, with larger or more complex projects ranging from $150,000 to over $300,000. Every job is priced case by case after a site inspection.
