Infinity pools are the ultimate statement of calm and refinement—but how do you build one that looks perfect and lasts?
The appeal of a seamless waterline is universal, yet the path to achieving it is filled with technical choices, design constraints, and regulatory steps.
From edge configurations to permits and positioning, this article walks you through what truly matters when planning an infinity pool—especially if you’re aiming for beauty that endures.
With over 30 years of experience in high-end pool design, we’re here to guide you from vision to precision.
Infinity Overflow Vs. Zero-Edge Overflow
Infinity pools, also known as vanishing edge or negative edge pools, are designed to prioritise both water quality and aesthetics. The water circulates through reverse hydraulics, continuously spilling over one or more edges into a balancing tank. Choosing the type of overflow system is primarily a matter of visual intent.
Deck-level or zero-edge pools offer a different effect. Water drains uniformly into a peripheral channel, keeping the surface still and highly reflective—perfect for flat terrain or enclosed courtyards where the goal is harmony and symmetry.
In some cases, a combination of both systems can create a strikingly original visual experience—blending a vanishing edge on one side with a mirrored deck finish on the others.
Choosing the right overflow configuration
Vanishing edge pools work beautifully on sloped ground. The overflow appears to disappear into the horizon, although in reality it is collected just beneath the edge in a purpose-built channel.
Deck-level or mirror pools are ideal for flat sites, where the water sits flush with the terrace, reflecting its surroundings with perfect clarity.

Finding The Right Pool Location
The positioning of your infinity pool is crucial, both aesthetically and practically. Several factors will guide this decision:
Â

Some homeowners prefer their pool close to the living space, creating seamless indoor-outdoor flow. Others seek calm and distance—a private retreat further from the main residence.
Depending on your lifestyle, your infinity pool can either be a secluded escape or an extension of your living space. Choosing the right proximity is a question of atmosphere: intimacy or integration.
TThe profile of the land plays an essential role in determining whether an in-ground or semi-inground pool is appropriate. Every bespoke pool project should be designed in harmony with its environment. On rocky or uneven terrain, an above-ground structure is often the most suitable solution.

If you live in France, understanding local building regulations is essential before starting your pool project.
Each town hall develops its own Plan Local d’Urbanisme (PLU), which determines where swimming pools may be built in relation to neighbouring properties and public roads. In smaller villages, this may be replaced by a simplified local map (carte communale).
If your property is part of a housing estate (lotissement), additional rules specific to the development may also apply. These can influence the location, size, and even the appearance of your infinity pool.
Explore the requirements before building your infinity pool
A reinforced concrete pool, a polyester shell, or a swimming pool kit facing the sun between 10:00 and 18:00 will benefit from the most favorable exposure; however, the direction of the breeze should be considered; the north wind can significantly cool the water. Trees near the swimming corridor complicate pool maintenance.
The importance of accurate drawings and plans
While some pool types (such as pre-formed or rectangular skimmer pools) can be built without detailed plans, this is not the case for infinity pools.
Neagtive edge and deck-level pools demand:
providing exact dimensions, including length, width, depth, and the position of key structural components such as the balancing tank, technical room, and access zones. It ensures spatial coordination with the house and surrounding landscape.
mapping out water circulation, return lines, overflow channels and pump placements. This ensures optimal flow, quiet operation, and long-term system efficiency.

Start planning early
Design, budget, authorisations and technical studies all require time. Planning well ahead lets you make informed decisions and avoid rushed compromises.
Work with experts
Infinity pools involve aesthetic finesse and technical precision. Surround yourself with professionals who understand both, and you’ll avoid costly errors while ensuring a lasting result.

What about permits?
Once your plans are finalised the next steps revolve around planning, regulatory checks, and selecting the right team to bring your pool to life.
In France, planning rules for pools depend on surface area, not volume.
For most private projects under 100 m², a simple prior declaration is usually sufficient. Larger pools or those with high enclosures may require a full building permit.
Always check with your local authorities—or consult a designer who can help you anticipate these steps early in the project.

Self- builder or pool builder ?
Infinity pools can be:
Custom-built by a professional contractor
Or created through self-construction, if you have the time and technical mindset
If you go through a builder, they will usually take care of the structure, waterproofing, filtration system, and finishes (reinforced membrane, mosaic, or coating). But bear in mind: even with a ten-year warranty in France, a poor design or inadequate detailing can compromise the pool’s longevity.
If building the pool yourself, choose construction methods and materials carefully. For reinforced concrete pools, shuttering blocks (polystyrene or concrete) are a popular option for experienced DIYers.
🌿 Reminder: The long-term reliability of an infinity pool depends as much on the quality of the materials as on the accuracy of the technical drawings.
Tips to Keep Your Infinity Pool Budget Under Control
Avoid costly mistakes by applying a few key principles:
👉 Compare estimates, don’t settle for the first quote.
👉 Be clear on what you expect from your infinity pool (aesthetic, maintenance, access).
👉 Source your own materials when possible: liners, covers, pumps, and water treatment systems.
👉 Monitor the construction process to spot issues early (unlevel overflow edges, poorly sealed pipework, misaligned components).

Conclusion
Infinity pools are a refined choice, offering not only aesthetic pleasure but also engineering sophistication. From choosing the right overflow system to ensuring regulatory compliance and construction excellence, each step matters.
Whether you’re building your pool yourself or working with a team, the right guidance transforms a complex process into a rewarding, beautiful result.
