Quick Summary
Selah Pools built a naturalistic freeform pool for the Quillin family in Argyle featuring 11,060 gallons, tiered spillway with six layers, three 18-inch sheer descents, round custom spa with massage jets, Buff Leuders stone coping, and Peerless Pebble Regatta Blue plaster.
Key Takeaways
- The Quillin family chose Selah to create a naturalistic retreat that responds to Argyle's rolling landscape rather than imposing upon it.
- The freeform pool features a six-tier spillway, three 18-inch sheer descents, round custom spa with massage jets, and 11,060-gallon capacity.
- Buff Leuders stone coping and NPT Ornament Peacock tile elevate the material palette while Peerless Pebble Regatta Blue plaster creates depth.
- The tiered spillway becomes a sculptural water feature with six cascading levels that animate the pool environment throughout the day.
In Argyle's rolling landscape, the Quillin residence called for something that felt less built than discovered. The design team shaped an 11,060-gallon freeform pool that follows the natural contours of the property, its organic curves suggesting a spring-fed swimming hole elevated by precise craftsmanship. The centerpiece tiered spillway creates six cascading levels, each one catching and redirecting light as water tumbles toward the main pool. Three eighteen-inch sheer descents punctuate the perimeter with ribbons of falling water, while a round custom spa anchors one end of the composition. Every line responds to the existing topography, creating an outdoor living space that feels indigenous to this North Texas terrain.

Materials & Finishes
Peerless Pebble Regatta Blue plaster lines the pool interior with a deep sapphire finish that shifts from navy to turquoise as light moves across the surface. Buff Leuders stone coping frames the irregular perimeter with straight-edge precision, its warm limestone tones harmonizing with the Texas landscape. NPT Ornament Peacock 1x2 tile creates waterline accents in rich teal, adding geometric contrast to the organic forms.

Design & Features
Two LED pool lights and one LED spa light extend usability into evening hours, while massage jets transform the custom spa into a hydrotherapy retreat. Raised beam construction allows the freeform shape to follow natural grade changes, and Nature2 mineral sanitization keeps water clear with minimal chemical intervention. Bubblers in the spa create gentle aeration, adding visual interest and therapeutic benefit.

Frequently Asked Questions
How do you design a pool that looks natural in North Texas?
A naturalistic pool design starts with reading the existing landscape and working with its natural contours rather than against them. For the Quillin project in Argyle, we shaped an organic freeform pool that follows the property's rolling terrain, using irregular curves that suggest a natural water feature. The material palette reinforces this approach—Buff Leuders stone coping connects to the native limestone geology, while the six-tier spillway creates cascading water you might discover in a Texas hill country creek. The result is a pool that feels discovered rather than constructed.
What makes a tiered spillway different from regular waterfalls?
A tiered spillway creates multiple cascading levels that break and redirect water flow, producing complex sound patterns and visual effects throughout the day. The Quillin pool's six-tier design means water tumbles through six distinct levels, each one catching light differently and creating its own acoustic signature. This approach generates more sensory interest than a single waterfall, while the multiple tiers allow the design team to control the water's energy as it moves from the raised beam level down to the main pool. It's engineering disguised as nature—precise construction serving an organic aesthetic.
Can massage jets really make a custom spa therapeutic?
Professional-grade massage jets transform a custom spa from a simple soak into genuine hydrotherapy. The Quillin spa includes targeted jets positioned to address key muscle groups, creating a therapeutic experience that elevates the outdoor living space into a wellness retreat. Combined with the round spa design that promotes natural circulation, bubblers that add gentle aeration, and LED spa lighting that extends enjoyment into evening hours, these jets provide both physical restoration and sensory richness. The Quillin custom spa demonstrates how thoughtful feature integration creates an experience far beyond heated water.
How do sheer descents change the pool experience?
Sheer descents create clean, ribbon-like waterfalls that add both visual drama and soothing white noise to the pool environment. The three 18-inch sheer descents in the Quillin pool punctuate the freeform perimeter with falling water that catches afternoon light and creates natural sound barriers for the outdoor living space. Beyond aesthetics, these features help circulate water and create subtle currents that enhance the swimming experience. They're particularly effective in naturalistic designs like the Quillin project, where the goal is to suggest natural water sources while maintaining the precision of modern pool engineering.
What's the benefit of freeform pools over geometric shapes?
Freeform pools follow natural topography and create more intimate swimming experiences with varied depths and organic curves. The Quillin pool's irregular perimeter creates multiple zones—the 3'6" shallow areas transition to 5' depths, generating spaces that feel more like natural swimming holes than engineered basins. This design flexibility allowed the team to work with existing grade changes using raised beam construction, often requiring less site disturbance than rigid geometric shapes. The result, as seen in the Quillin outdoor living space, is a pool that belongs to the Argyle landscape rather than being imposed upon it.
