GB IV Designs · Bee Cave, Texas

Custom pool design and construction in Austin.

GB IV Designs is an Austin custom pool builder and aquatic design, engineering and construction firm. We design pools, spas, water, fire, structures and landscape as one composition — then build it in gunite with the same team that drew it.

Founded by George “Bo” Barnett IV, a pioneer of large‑format porcelain in aquatic environments and a Coverings and Watershape University educator, the firm designs for architects across the country and works as a custom pool builder exclusively in Austin and the Texas Hill Country.

Design

Award-winning aquatic and outdoor architecture, modelled in 3D before it is built.

02

Engineering

Hydraulics, elevations, structural complexity and difficult Hill Country sites resolved on paper first.

03

Material Innovation

Large-format porcelain, glass, specialty finishes and the installation systems that make them permanent in water.

04

Craft

Gunite, waterproofing, tile, stone and plaster executed by specialists and inspected by the designers.

05

Complete Environments

Pool, spa, landscape, structures, fire, kitchen and lighting designed as one composition.

06

Industry Leadership

Teaching, speaking, awards and trade-organisation service that keep the firm at the front of the field.

How we work

Our pool building process.

From a site walk and an honest conversation about investment to commissioning, training and a written warranty.

  1. Step 1

    Consultation & Site Study

    Listen, walk the site, align on budget

    We meet at the property, walk the site with you and document grade, soil, access, utilities, trees, views and how you actually want to live outdoors. We discuss investment range honestly before anyone draws a line.

    TimingScheduled within 1–2 weeks.
  2. Step 2

    Concept Design & 3D Model

    See it before it exists

    Bo and the design team develop the concept — geometry, elevations, water and fire, structures, materials — and build a 3D model you can walk through. We revise until the design is right, not until the hours run out.

    Timing3–6 weeks.
  3. Step 3

    Engineering, Proposal & Permitting

    Resolve the hard parts on paper

    Structural, hydraulic and equipment engineering are completed, the proposal is itemised line by line, and we prepare and manage permit, HOA and municipal submissions.

    Timing3–8+ weeks, permit-dependent.
  4. Step 4

    Construction

    The design team builds the design

    Excavation, steel, gunite, plumbing and electrical, waterproofing, tile and stone, decking, structures, equipment and landscape — sequenced and inspected by the people who drew the plans. You receive a schedule and regular site reports.

    Timing14–28 weeks, scope-dependent.
  5. Step 5

    Commissioning & Handover

    Start-up, training, warranty

    We balance the water, programme the automation, verify every system and walk you through operating the pool. Warranty documents and a maintenance plan are handed over in writing.

    Timing1–2 weeks.

Why GB IV

Why Austin homeowners choose GB IV.

What sets GB IV apart from other Austin pool builders.

01

One accountable team

The people who design your pool are the people who build it. Your project is not handed to a stranger once the drawings are signed.

02

Gunite, not shortcuts

We build in gunite — shaped to your yard rather than dropped into it — and engineer every shell for Austin's limestone and clay.

03

Proof, not adjectives

Coverings CID recognition in 2025 and 2026, a Southwest Pool & Spa Show Gold for technical and engineering achievement, and 23 SWPSS category awards in two years.

04

Built to be published

Our projects are photographed, awarded and written about because they are designed to a standard most pool contractors do not attempt.

Before you call

Austin pool FAQs.

All FAQs

Our projects typically begin around $250,000 and most fall between $300,000 and $600,000; estate environments with perimeter overflows, structures and complete landscapes exceed $750,000. Exact pricing follows the site study and design, and our proposals are itemised line by line.

Most GB IV projects run six to nine months from the first consultation to handover: three to six weeks of design, three to eight weeks of engineering and permitting, and fourteen to twenty-eight weeks of construction depending on scope. Estate-scale environments with structures, vanishing edges and extensive hardscape take longer, and we tell you so at the proposal stage.

The designers. GB IV is a true design-build firm: the people who draw the plans manage and inspect construction, and Bo Barnett remains involved in every project from concept to handover. You are never handed to a stranger after the contract is signed.

GB IV builds custom pools in Austin, Bee Cave, West Lake Hills, Rollingwood, Barton Creek, Lakeway, Spanish Oaks, Lake Travis, Steiner Ranch, Dripping Springs, Driftwood and Tarrytown, across Travis, Hays and Williamson counties. Our office is on Highway 71 in Bee Cave. Construction is limited to Central Texas so the designers can be on site; design engagements for architects and estate owners are accepted nationwide.
