Hill Country Pool Builder
Design Around the Land First, Then the Features
Hill Country lots are the reason many people move here: long views, live oaks, limestone, elevation. They’re also why a pool here takes more than a good drawing. Slopes, rock, drainage, and soil all shape what you can build and what it costs.
Worthey Aquatics designs and builds custom gunite pools for sloped and view lots across Boerne, Fair Oaks Ranch, The Dominion, Kerrville, Fredericksburg, Comfort, Johnson City, and the greater Hill Country. Our approach is simple: design around the land first, then the features.

Sloped Lots
Can You Build a Pool on a Sloped Lot?
Usually, yes. The real questions are how and at what cost. On a sloped site, the pool structure has to account for:
Grade Change
The downhill side of the pool may sit well above natural grade, so that wall becomes a structural, exposed element.
Retaining & Backfill
Uphill cuts and downhill fills may need retaining walls and engineered backfill.
Rock & Caliche
Limestone can slow excavation and may need specialized equipment.
Drainage
Water moving downhill has to be routed around the pool, deck, and home, during construction and permanently.
Access: narrow or steep access affects which equipment can reach the site. A site visit tells us what your lot requires.
Negative-Edge (Infinity) Pools
When a Negative Edge Works, and When It Doesn’t
A negative edge lets water spill over one or more sides into a lower catch basin, so the pool appears to meet the horizon. Done right, it’s the defining feature of a Hill Country property. Done on the wrong lot, it’s an expensive detail nobody notices.
A negative edge tends to make sense when:
- There’s a real view from the main living areas and patio
- The lot has enough grade change to hide the catch basin below the sightline
- You’re comfortable with the added equipment and maintenance
What it adds technically:
- A catch basin (trough) sized to hold the water in motion
- A dedicated pump and plumbing for the edge
- Precise elevation and level work on the weir edge
- Often, more exposed finished wall on the downhill side (tile, stone, or plaster)
Alternatives that can deliver the effect for less: perimeter overflow on one side, a raised spa spillover toward the view, or sheer descents on a raised wall.

How We Approach a Hill Country Pool
Five steps, from the first walk-through to start-up. Many of our Hill Country pools are designed so the land, not just the drawing, drives every decision.
1. Site visit and walk-through. We look at slope, view lines, rock, trees, drainage, access, and where the equipment pad can live.
2. 3D design. You see the pool in your actual setting before construction.
3. Engineering and permitting. Engineered plans and site drawings, HOA/ARC submittals, and city/county permits.
4. Construction. Layout, excavation, steel, plumbing, gunite, tile and coping, decking, interior finish and start-up: about 8 to 16 weeks of construction depending on complexity.
5. Start-up and care. Water chemistry, equipment orientation, and optional weekly service from the same company.

New Custom Homes
Building With a New Custom Home?
Many of our Hill Country pools are part of new custom-home builds. When the pool builder joins during design:
- Pool and deck elevations are coordinated with finished floor and grading
- Drainage is designed once, for the whole site
- Utilities are routed before flatwork
- Excavation is sequenced to protect the home and landscape
Builders, architects, and landscape designers: send us a site plan and we’ll give you a feasibility read on the pool scope. Call 210-760-7236.

Areas We Serve in the Hill Country
We build for view lots, rolling terrain and rocky limestone sites across seven Hill Country areas.
Schedule a Site Evaluation
Boerne: view lots, limestone and shallow rock, and gated-community architectural review. Boerne pools
Fair Oaks Ranch: larger lots and rolling terrain where grade change can shape the pool. Fair Oaks Ranch pools
The Dominion: luxury estates on the northwest side of San Antonio, with HOA review to plan for.
Kerrville: ranch properties and long-view sites, often sloped or rocky limestone, with a longer drive and more planning. Kerrville pools
Fredericksburg: ranch and hillside properties with long views and rocky limestone; the distance means we plan site visits and logistics ahead.
Comfort: rural Hill Country lots where slope, rock and a longer drive all factor into design and scheduling.
Johnson City: Hill Country ranch and view properties with limestone soils and grade change; as with our other outlying areas, we plan site visits and logistics ahead.

Frequently Asked Questions
Common Questions About Hill Country Pools
Can you build a pool on a steep Hill Country lot?
In most cases, yes. Sloped lots usually need structural design for the downhill wall, retaining or backfill, and a drainage plan. A site visit tells us what your lot requires.
Do negative-edge pools cost more?
Yes. A negative edge adds a catch basin, a dedicated pump and plumbing, precise elevation work, and often more finished wall area on the downhill side.
Is my lot right for an infinity edge?
It works best when there’s a real view from your main living spaces and enough grade change to hide the catch basin. If not, a raised spa spillover or perimeter overflow may deliver the look for less.
Does rock make a pool more expensive?
Limestone and caliche can slow excavation and may need specialized equipment, which adds cost. We assess this during the site visit.
Do you work with my home builder and architect?
Yes. We coordinate with builders, architects, and landscape designers so pool, deck, grading, drainage, and utilities are planned together.
Which areas do you serve?
Boerne, Fair Oaks Ranch, The Dominion, Kerrville, Fredericksburg, Comfort, Johnson City, San Antonio, and surrounding Hill Country communities. Kerrville, Fredericksburg, Comfort and Johnson City are a longer drive from our San Antonio office, so we plan site visits and logistics ahead.
