Week 0Decide what the pool is for
Before a spade touches the lawn, one decision sets every other: what the pool is for. Cooling off, real swimming, or a heated soak twelve months a year? Ours is a family pool — an 8 × 4 m rounded rectangle with room to swim and a shallow end to stand in — and its outline is sprayed on the grass.

Week 1Set out and dig
The digger arrives and the lawn becomes a hole with a slope in it — deeper at one end than the other. That slope is the first design decision you can see: 1.2 m where children will stand, 1.8 m where adults will swim. If the ground is wet, a valve in the floor stops groundwater from floating the finished pool.

- ExcavationDigging the hole the pool sits in — the shell's shape plus working room around it, and the slope from the shallow end down to the deep end already in the ground.Lire la fiche complète →
- Shallow endThe standing-depth zone of the pool, typically 1.0–1.2 m — where children play, adults wade and steps arrive.Lire la fiche complète →
- Deep endThe deepest zone of the pool, typically 1.8–2.0 m in family pools — deep enough for free swimming and treading water.Lire la fiche complète →
- Hydrostatic valveA one-way valve in the pool floor that lets groundwater into the empty basin instead of letting it lift the shell out of the ground.Lire la fiche complète →
Week 2–3The shell
Steel goes in, concrete is sprayed over it, and the hole becomes a basin. Everything built into the pool is formed now, while the walls are bare: the steps, the tanning ledge, the drain at the deep point and the inlets that will push clean water back. What you decide this week is cast in concrete — literally.

- Beach entryA gently sloping, zero-depth entry that starts at deck level and descends like a natural shore — no steps at all.Lire la fiche complète →
Week 4The edge
How the pool meets the deck is the most architectural choice of the build. Ours is a skimmer pool: a ring of travertine coping caps the wall, the water will sit a hand's width below it, and two wall skimmers will sip the surface clean. A deck-level pool would instead spill over its rim into a hidden channel.
Mots que vous entendrez cette semaine
- CopingThe ring of finished stone or masonry that caps the pool wall at the waterline — the edge your hand grabs and your eye reads as the pool's outline.Lire la fiche complète →
- FreeboardThe vertical distance between the water surface and the top of the pool edge — typically ~15 cm in skimmer pools, near zero in deck-level overflow pools.Lire la fiche complète →
- SkimmerA wall-mounted unit that draws the top few centimetres of pool water into the filtration circuit, harvesting floating debris, dust and oils before they sink.Lire la fiche complète →
- Deck-level overflowAn edge system where the water stands flush with the surrounding deck and continuously spills into a hidden perimeter channel, from which it is filtered and returned.Lire la fiche complète →
- Infinity edgeA vanishing-edge wall lowered to a precise weir so water sheets over it into a catch basin below, visually merging the pool surface with the landscape behind.Lire la fiche complète →
- Overflow gutterThe perimeter channel of a deck-level pool that catches the continuously overflowing water — finished as a grate or a narrow slot.Lire la fiche complète →
- Balance tankA buffer reservoir that overflow and infinity pools need: it receives the water spilling over the edge and feeds the pump, absorbing the level swings caused by swimmers.Lire la fiche complète →
Week 5The surfaces
Now the basin gets its skin, and the colour of the water gets decided — not by the water, which is nearly clear, but by the finish under it. Ours is white plaster, which reads as bright turquoise once it is wet, with a band of porcelain tile at the waterline where scale and sunscreen collect.
Mots que vous entendrez cette semaine
- Pool plasterA seamless cementitious interior finish (marcite, quartz or polished aggregate) troweled over the shell.Lire la fiche complète →
- Porcelain pool tileFully vitrified ceramic tile with near-zero water absorption — frost-proof, colorfast and chemically inert, the most durable pool interior.Lire la fiche complète →
- Mosaic tileSmall-format tile (2–5 cm) mounted on mesh sheets — the format that wraps curves, radii and Roman steps without cutting.Lire la fiche complète →
- Pool groutThe joint filler between pool tiles — in pools always a water-resistant epoxy or high-grade cementitious grout that survives permanent immersion and chemicals.Lire la fiche complète →
- Waterline tileThe band of tile at the water's surface where scale, sunscreen and grime concentrate — tiled even in otherwise plastered pools because tile scrubs clean.Lire la fiche complète →
Week 6The deck
The pool is only half the picture; the deck is the room it lives in. Pavers go down around the coping, the lounging side gets its two metres, everything drains away from the water, and at one end a pit is formed where the cover's roller will hide.

Week 7Water in
Thirty-two hours of garden tap, and the plant room wakes up: pump, filter, heater. From now on the water lives in a loop — out through the skimmers and drain, through the filter, back through the inlets — and keeping it clear is a five-minute weekly ritual, not a chore.

Week 8Fit-out
The fittings people actually touch. Warm lights in the wall so the pool is still there at nine in the evening, a ladder at the deep end so swimmers get out without crossing the shallow zone, and — if length is short — a current to swim against.
Mots que vous entendrez cette semaine
- Pool lightsSealed LED fixtures set into the pool wall about 50 cm below the waterline, wired through conduits cast into the shell.Lire la fiche complète →

- Counter-current unitA powerful jet that produces an adjustable current to swim against — endless swimming in place, even in a 5-metre pool.Lire la fiche complète →
Week 9Cover and care
The last delivery is the one that pays for itself: a cover that goes on every night and halves the heating bill. Then the robot takes over the floor, and the pool asks for twenty minutes a week — until autumn, when it gets tucked in for winter.
