Project Spotlight: Engineering a 10,000 Sq. Ft. Modern Spanish Revival in The Dominion
When affluent buyers research The Dominion custom home builders, they are looking for more than just a contractor; they are looking for an architectural engineering firm capable of executing monumental visions. Spanning over 1,600 acres of pristine Texas Hill Country terrain, The Dominion remains San Antonio’s premier master-planned, guard-gated community.
Recently, the Bayless Custom Homes team was tasked with a monumental project in this exclusive enclave: engineering and constructing a sprawling, 10,000-square-foot Modern Spanish Revival estate. This project serves as a perfect cornerstone in our luxury home builders in San Antonio portfolio, demonstrating exactly how we overcome severe topographical challenges to deliver magazine-quality results.
Here is an exclusive, behind-the-scenes look at the engineering, logistics, and execution of this legacy estate.
The Architectural Vision: Modern Spanish Revival
The clients came to us with a distinct vision: they wanted the timeless permanence of classic Mediterranean architecture fused with the airy, uncluttered flow of contemporary design.
We executed this through the Modern Spanish Revival aesthetic. The exterior of the 10,000-square-foot estate was grounded by thick, hand-troweled stucco walls and a low-pitch red barrel tile roof to combat the Texas heat. However, instead of the small, deeply recessed windows found in historic Spanish Colonial homes, we integrated massive, steel-framed vanishing glass walls that flooded the interior with natural light. (You can explore the specific pillars of this highly sought-after style in our guide: Mastering Modern Mexican and Spanish Revival Architecture in San Antonio).
The Engineering Challenge: Severe Slopes and Structural Steel
While the architectural renderings were breathtaking, the physical reality of the lot presented a massive engineering hurdle. The property was situated on a severe Hill Country slope. Building a 10,000-square-foot, single-story footprint on a steep incline requires far more than a standard slab-on-grade foundation.
To ensure absolute structural permanence, our engineering team had to design a highly complex foundation system. This involved drilling deep concrete piers directly into the limestone bedrock and constructing massive, multi-tiered retaining walls to stabilize the massive footprint. (As we frequently warn our clients, understanding these geological realities before you purchase land is vital. Read our Definitive Guide to Choosing the Perfect Lot for Your San Antonio Custom Home).
Furthermore, achieving the “vanishing wall” aesthetic—where 30-foot spans of glass disappear seamlessly into the masonry—meant the roof could not be supported by traditional timber framing. We had to coordinate the complex logistics of craning in massive, commercial-grade structural steel beams across the sloped terrain to support the soaring vaulted ceilings and the heavy barrel tile roof without obstructing the panoramic views.
The Solution: Uncompromising Logistics and Transparency
A project of this magnitude, governed by The Dominion’s strict Architectural Control Committee (ACC), requires flawless project management.
By intentionally limiting our volume of simultaneous builds, our dedicated project managers were on-site daily, coordinating the intricate dance between heavy equipment operators, structural steel welders, and artisan stonemasons. Because the clients were managing their corporate businesses during the build, they relied heavily on our digital portal—which provided daily site logs, budget tracking, and weekly drone updates—to stay completely connected to the project.
Most importantly, we utilized our strict “No Allowance” bidding process. We finalized the pricing for the complex foundation engineering, the structural steel, and the imported artisanal zellige tile before the first shovel hit the dirt. This guaranteed the clients were insulated from the devastating mid-build price hikes common with volume builders.
The Result: A Resort-Style Legacy
The finished estate is a masterclass in seamless indoor-outdoor synergy. The vanishing glass walls open the massive great room entirely to a central, sun-drenched courtyard featuring a resort-style infinity pool that cascades down the topographical slope.
Inside, the home features a fully appointed hidden scullery (prep kitchen) for seamless entertaining, and a comprehensive master wellness sanctuary equipped with a built-in glass-front infrared sauna and circadian rhythm lighting.
“Building a 10,000-square-foot home on a steep slope felt like an overwhelming risk, but the Bayless team engineered every square inch flawlessly. Their absolute financial transparency and daily communication allowed us to actually enjoy the process. They didn’t just build our house; they protected our investment.” — The Homeowners

Frequently Asked Questions
How long does it take to build a 10,000-square-foot custom home in The Dominion?
Due to the intricate foundation engineering, extensive structural steel requirements, and the time required for ACC (Architectural Control Committee) approvals, a home of this magnitude typically requires an 18 to 24-month construction timeline from the initial design phase to the final walkthrough.
Are there strict building requirements in The Dominion?
Yes. The Dominion has one of the most rigorous Architectural Control Committees in Texas. They dictate strict guidelines regarding exterior masonry percentages, approved roofing materials (like barrel tile or slate), minimum square footages, set-back requirements, and comprehensive landscaping plans to protect the community’s exclusive aesthetic.
Can I build a custom home on a steep sloped lot?
Absolutely. Sloped lots often provide the most breathtaking, panoramic views in the Texas Hill Country. However, buyers must be financially prepared for the significant “hidden costs” of site preparation, which include extensive excavation, deep concrete piers, and structural retaining walls.
