Free-Form Lagoon Pools

Resort Luxury at Home

Imagine stepping into your backyard and feeling like you’ve arrived at a luxury resort. Organic shapes, multiple depth zones, beach entry, natural stone features, and water features that cascade and flow. That’s what a freeform lagoon pool delivers.

While infinity pools make architectural statements, freeform pools create experiential retreats. They’re about how the pool feels to use and how it integrates with nature rather than how it photographs as a design object.

Mossman Brothers Pools has designed dozens of freeform lagoons, and they’ve become increasingly popular with our luxury Scottsdale clientele. A freeform pool says: “This property is my private resort. This is where I escape.” 

What Makes a Pool "Freeform"

🌊 Curved, flowing edges

Natural-looking curves rather than straight lines or precise angles

✨ Irregular perimeters

The pool outline looks like it could occur in nature—think natural water features like ponds or lagoons

🏊 Multiple depth zones

Rather than consistent depth, the pool transitions from shallow to deep, often with beach entry areas

💎 Natural landscape integration

The pool merges with the landscape rather than sitting as a separate geometric feature
Within this freeform concept, there’s enormous design variation. Some freeform pools are kidney-shaped. Some have coves and inlets. Some feature island features within the pool. Some include separate spa areas. The design possibilities are nearly limitless because you’re not constrained by geometric precision.

Design Elements of Freeform Pools

Jeff Mossman designs each freeform pool specifically for its property, but most feature several common elements:

Beach Entry

A sloped entry area (like a natural beach) rather than a ladder or step entry. Water depth transitions from 0 inches at the entry to 3-5 feet gradually. Beach entries are comfortable for young children, accessible, and feel natural.

Multiple Depth Zones

Beyond the beach entry, the pool typically features shallow areas (2-3 feet) for wading or lounging, medium depths (4-5 feet) for swimming, and deeper areas (6-8 feet) for diving or exercise. These zones create multiple functionality areas.

Curved Edges

Rather than straight edges, the pool outline curves naturally. Curves can be gentle (subtle) or dramatic (pronounced coves and peninsulas). The curvature should look intentional but natural.

Natural Stone Integration

Rocks, boulders, and stone features integrate with the pool rather than being purely functional. They might form a spillway for a waterfall, create a shallows area, or frame the beach entry. Stone colors and textures complement Arizona’s natural landscape.

Water Features

Many freeform pools include sheer descent waterfalls, natural spillways, bubblers, or fountains. Water features add visual interest, sound, and a sense of nature.

Spa Integration

A freeform pool often includes an attached spa area with its own jets and heating. The spa is designed as an integrated element rather than a separate feature, maybe connected by a beach entry or a walk-through shallow zone.

Lighting

Underwater and landscape lighting creates ambiance at night. LED lighting allows color changes and creates different moods depending on season or occasion.

Freeform Pools in Scottsdale's Desert Landscape

Freeform pools integrate beautifully with Arizona’s natural environment:

Native Plant Integration

Desert shrubs, saguaro cacti, and native trees surround the pool naturally. Rather than fighting the desert landscape, freeform design embraces it. The pool becomes another natural water feature in a desert ecosystem context.

Architectural Compatibility

While freeform pools work with any architectural style, they're particularly compatible with:
• Mediterranean and Tuscan homes
• Southwestern-style properties
• Rustic luxury estates
• Contemporary homes with natural materials (earth tones, stone, wood)

Topography Advantage

Properties with slopes and varied terrain work beautifully for freeform design. The pool can follow the natural contours of the land rather than requiring extensive grading to create a flat surface.

Large-Lot Properties

Scottsdale's luxury properties often feature multiple acres. Freeform pools take advantage of this space, curving through the landscape and creating multiple experience zones.

Freeform Pool Costs

Freeform lagoon pools in Scottsdale typically range from $100,000 to $300,000+, depending on:

Size

Larger pools cost more (more excavation, concrete, materials)

Complexity

Simple curved shapes cost less; complex multi-cove designs with islands cost more

Natural stone features

Rocks and boulders add cost but enhance natural appearance

Water features

Waterfalls, spillways, and bubblers add functionality and cost

Spa integration

An attached spa adds $20,000-$50,000

Landscape integration

Extensive planting and hardscape design add to total investment
A mid-range freeform pool (3,000-4,000 sq ft, natural stone features, waterfall, beach entry) typically costs $120,000-$200,000. Premium lagoons with extensive stone work and multiple features can exceed $300,000.

Freeform Pool Maintenance

Freeform pools have similar maintenance needs to traditional pools but with some considerations:

Beach Entry Maintenance

The beach entry slopes gradually, so debris can settle in shallow areas. Regular brushing prevents algae on shallow floors.

Multiple Zones

Circulation should reach all zones equally. Proper pump placement and return line positioning ensure even water movement throughout the pool.

Stone Features

Natural stone features require monitoring for any mineral deposits or algae growth. Regular brushing keeps stone surfaces clean.

Plant Integration

Landscape plants surrounding the pool need maintenance. Falling leaves require skimming. Some plants may need trimming to prevent overhanging the pool.

Spa Maintenance

If your freeform pool includes an attached spa, the spa requires separate attention—jets need cleaning, filters need maintenance, chemicals need balancing.
Professional maintenance is valuable for freeform pools because of the additional complexity. Monthly professional visits help ensure all zones are circulating properly, stone features are clean, and systems are optimized.

Freeform Pool Experience

What makes freeform pools special isn’t just their appearance—it’s how they feel to use:

Resort Escape

Stepping into a freeform lagoon feels like a vacation. The organic shapes, water features, and landscape integration create a sense of escape from daily life.

Multiple Use Zones

You can swim laps in deeper areas, wade in shallows, relax on submerged benches, enjoy the spa, or just sit on the deck and watch the water. Different zones support different activities and moods.

Family Functionality

Young children can safely enjoy the beach entry without needing supervision in deep water. Adults have deeper zones for exercise. Everyone finds their comfort zone.

Landscape Connection

Rather than feeling like a disruption to your landscape, a well-designed freeform pool feels like a natural addition. The water, plants, stone, and hardscape all feel intentional together.

Entertaining Backdrop

The organic beauty of freeform pools creates a stunning backdrop for entertaining. The visual interest and multiple zones make the pool a focal point without feeling sterile.

Is a Freeform Pool Right for Your Property?

Freeform pools work best when:
  • Your property has adequate space for organic shapes (minimum 3,000 sq ft for a functional freeform pool)
  • You want a resort-like retreat rather than an architectural statement
  • Your landscape is naturally varied (slope, trees, views to frame)
  • Your architectural style complements natural materials and organic design
  • You're committed to proper maintenance of additional landscape and stone features
  • Your budget allows for the investment (typically $100,000+)
During your design consultation, Jeff will evaluate whether a freeform lagoon is the right approach for your property or if another style might work better.

The Freeform Philosophy

Freeform pools reflect a different design philosophy than geometric or infinity pools. Rather than precision and architectural statement, they’re about integration and creating an experience. Rather than being the most visible feature from above, they’re about how they feel to use and how they integrate with your landscape.

If that philosophy resonates with you—if you want your backyard to feel like a natural retreat rather than an architectural showcase—a freeform lagoon pool is worth exploring.
