Here are some photos of real-life lagoons in various locations.
A lagoon powered by Crystal Lagoons® technology changes the game: it doesn’t operate as an “add-on,” but as the project’s commercial centerpiece, capable of turning a development into a destination, increasing value per square meter, accelerating sales, and opening new revenue streams.
In real estate, ROI isn’t something you “feel”: it’s measured. And when we talk about amenities, the critical question for any developer isn’t whether something looks spectacular, but how much it increases value, how much it accelerates sales velocity, and how sustainable (and defensible) those results are over time.
That’s where a lagoon powered by Crystal Lagoons® technology changes the game: it doesn’t operate as an “add-on,” but as the project’s commercial centerpiece, capable of turning a development into a destination.
The Direct Impact on Price per Square Meter
Integrating a crystalline lagoon transforms a project’s economic geography. By bringing idyllic beach life to any location—whether it’s inland, in the heart of a city, or in the middle of the desert—it creates immediate value.
What does “increasing value” really mean in a real estate project?
In practice, “value uplift” is expressed through four variables that directly impact returns:
- Price premium per square meter (pricing power)
- Faster sales velocity (absorption)
- Greater asset appreciation (resale/capital appreciation)
- New revenue streams (in public-access models), where the lagoon can operate with paid entry and create additional income streams.
The data-driven answer: how much value can increase with a crystalline lagoon
There isn’t a single percentage that applies to every market, but real-world cases show consistent impacts on pricing and commercial performance.
Case 1: Epperson (Florida, USA) — pre-sale premium and accelerated sales velocity
At Epperson, once the addition of a crystalline lagoon was announced, sale prices increased by 21% in the pre-construction phase, while competitors rose only 1% to 5%.
In addition, between January and June 2021, sales increased by +174% (compared to 2020), reaching 342 units sold.
The result: the “lagoon effect” doesn’t just allow you to charge more but also reduces the time it takes to convert interest into signed contracts.
Case 2: Baía Kristal (Cartagena, Colombia) — appreciation and accelerated sell-out
At Baía Kristal, the sale value per m² doubled (100%) in 2.3 years, while comparable projects grew only 5% to 15% over the same period.
The project sold 1,560 apartments in 2.3 years, averaging 56 units per month, when it was originally projected to take 7 years to sell out.
The result: when an amenity becomes “iconic,” appreciation can be accompanied by an equally—or even more—powerful advantage: sales velocity.
Why a crystalline lagoon truly moves ROI (and isn’t comparable to a pool)
The key difference is that a crystalline lagoon doesn’t compete in the “amenity” category: it competes in the “lifestyle” category. And that changes willingness to pay.
1) True differentiation (not a commodity)
A traditional pool is replicable. A crystalline lagoon creates an immediate “wow factor” and a sellable narrative (“beach lifestyle”) that multiplies appeal and memorability.
2) Sustainability and efficiency that support the model
The value proposition isn’t just aesthetic: it’s also operational efficiency. Crystal Lagoons® sustainable technology can operate using up to 100 times fewer chemicals and only 2% of the energy used by conventional swimming pool filtration systems.
In addition, it enables low water consumption: up to 33 times less water than a golf course and 40% less water than a park of the same size, and it can use fresh, salt, or brackish water.
What this means for ROI: an amenity that drives pricing and sales, while also helping meet sustainability/ESG criteria, tends to be more defensible over time.
4. The PAL® Model: Monetization Beyond Real Estate Sales
A unique innovation maximizing ROI for investors are Public Access Lagoons® projects, also known as PAL® developments. This business model allows the lagoonto operate as a public tourist attraction through ticket sales.
This turns the amenity into an independent business unit that generates perpetual revenue through:
· Daily ticket sales (ticket revenue).
· Corporate events and weddings.
· Retail, food & beverage, and watersports around the lagoon, plus concerts, outdoor cinema, and hundreds of other activities.
How to estimate “how much” ROI increases in a project
If you’re evaluating integrating a crystalline lagoon, a simple, but solid, model typically includes:
- Projected premium by unit type and view (lagoon-front vs. interior)
- Absorption effect: expected monthly sales with and without the lagoon
- Impact on CAC / commercial efficiency: more organic leads, better conversion, less reliance on discounts
- Land value / early-phase uplift: pre-sales and construction stage (where much of the upside is captured)
- Comparative OPEX: energy, chemicals, maintenance (and the impact on NOI, especially in hospitality)
- Complementary revenues (if applicable): ticketing + events + F&B + commercial lease income
When an amenity is measured in sales, it speaks for itself.
So, how much does a property’s value increase with a crystalline lagoon?
The cases demonstrate that the impact can show up as a price premium (e.g., +21% in pre-sales at Epperson), faster sales velocity (+174%), and appreciation that far outperforms the market (e.g., +100% in 2.3 years at Baía Kristal).
In a market where differentiation is no longer optional, a crystalline lagoon isn’t a “nice-to-have” expense: it’s a business tool to sell faster, sell better, and sustain value with a sustainable value proposition.
