Infinity Horizon in Catalonia
When the pool water disappears into the Mediterranean.
Perched on a hillside just north of Barcelona, this infinity pool was designed not to stand out — but to dissolve. Into the view. Into the silence. Into the sunlight shimmering over the Mediterranean.
From the first sketches, we knew this project would be all about alignment. The house, with its sharp contemporary lines, dictated a restrained geometry. The sea, always visible from the plot, demanded openness. No distractions. No noise.
We drew a single horizontal line, running uninterrupted from the spa to the far edge. That became the water level. Everything else revolved around it.

Not just a pool — A line.
Overflow runs along the full length of the pool, cascading in silence down a dark surface. The edge doesn’t call attention to itself — it simply lets the water go. And from the terrace, it’s impossible to tell where the pool ends and the sea begins.
There’s no visual break. Not even at the far edge. We designed the overflow profile so the top of the wall disappears entirely from view. You never see the structure — just water flowing over what seems to be… nothing. That’s what makes it unsettling. And beautiful.
The integrated spa extends the waterline without the slightest elevation. It’s part of the pool — and yet, separate. Calmer. Warmer. Private.
What you don’t see is everything
The local plant room is hidden beneath the house, fully underground and below water level. No bulky machinery. No intrusive noise. Just clean lines and quiet engineering.
Inside, a smart hydraulic layout runs the system with surgical precision. The in-floor cleaning system operates like a discreet choreographer — jets rise, sweep, disappear. No hoses. No vacuum. Just a spotless floor every morning.
Water flows from the bottom upward, filtered, balanced, replenished. The overflow catches it. The surge tank regulates it. And the mirror stays flat.
Precision planning, remote execution
This project was built by a local team. Our role: to make sure they had everything they needed. We produced detailed, scale-accurate plans — structural, hydraulic, architectural. Every level, every corner, every pipe run was defined in advance.
The construction process followed a flexible but structured rhythm. Site visits for key phases — height checks, overflow testing, edge alignment. And in between, remote support. Email, video calls, photo analysis. When the coping stones were laid, we adjusted them centimetre by centimetre — from a distance.
The laser levels told us everything. No margin for error. A 1 mm misalignment would have ruined the mirror effect.
Materials chosen to disappear
The pool finish — neither too dark, nor too reflective — was selected to play with light without distorting it. On some days, it reflects the sky. On others, it turns transparent. At sunset, it melts into amber.
The coping is soft underfoot, matt-textured, barely warmer than the surrounding terrace. And the spa? It’s there, of course — you can hear the gentle bubbling — but it doesn’t break the line.
What you don’t see matters most
The overflow works in silence. The hydraulic balance — flow rate, tank volume, return inlets — was fine-tuned for stability. No turbulence. No splashing. Just water sliding over the edge like glass.
From inside the pool, you can’t see the gutter. From outside, you can’t see the technical room. Everything is hidden, so the view stays clear. Guests still stop mid-sentence when they see it for the first time. Especially at dusk. There’s a moment of hesitation — as if unsure whether to approach or just watch.
Because designing an infinity pool isn’t about drawing a rectangle. It’s about timing, light, angles, expectations. In Catalonia, we had to deal with coastal winds, uneven terrain, high salinity in the air. We adapted. A bit more anchoring here, a different pump specification there.
This isn’t a perfect project. No project ever is. There were questions we hadn’t anticipated. Delays. Heatwaves. A few deliveries arrived late. But the idea held. And it still holds. The pool is there, quietly doing what it was designed to do. Catch the sky. Let it go. Repeat.
This project reflects what we care most about: letting water, light and architecture speak the same language — without ever disturbing the balance.
