The kitchen flows naturally into the living space. Storage appears exactly where you need it. Natural light floods the primary suite without sacrificing privacy. The outdoor living area feels intentional, not tacked on. Every detail works.
This isn’t expensive custom architecture. It’s what happens when 30 years of real-world building experience gets distilled into ready-to-build home plans that cost a fraction of bespoke design fees.
Thomas Retnauer, Chief Visionary of RBA Architects and founder of RBA Home Plans, has spent three decades learning a truth most in the residential design industry overlook: when a home is designed thoughtfully, life inside becomes easier, smoother, and more enjoyable. Now, he’s making that level of design accessible to families and builders who have long been forced to choose between generic plans and unaffordable custom work.
People are frustrated with house plans that look good on paper but don’t live well day to day,” Retnauer says. “They trust us to deliver clarity, confidence, and plans that genuinely improve how they live.”
RBA Home Plans represents the residential design division of RBA Architects, a firm that has shaped residential development across Virginia, North Carolina, South Carolina, Maryland, and beyond. With more than 85 local, regional, and national awards, the firm’s reputation rests on thousands of homes that have been built, lived in, and refined through decades of field-tested insight.
The distinction matters in an industry flooded with mass-produced drawings created by designers who have never walked a job site or spoken to a homeowner five years after move-in. RBA’s plans emerge from a working architectural practice that designs multifamily developments, coastal residences, and mixed-use communities today. Every floor plan carries embedded knowledge about construction sequencing, cost control, framing logic, and marketability.
“Our designs aren’t theoretical or generic,” Retnauer says.
“They’ve been built, refined, value-engineered, and lived in across the Mid-Atlantic. We know what works, what sells, and what creates long-term value.”
RBA’s expertise was shaped by solving a major industry challenge: offering high-quality, architect-designed home plans that still meet builders’ needs for efficiency, speed, and cost control. Instead of letting design integrity and buildability compete, RBA fused them together and that fusion now defines the brand.
The result is a curated library of coastal, craftsman, modern, and farmhouse designs, each focused on how people actually live. RBA doesn’t chase trends. Their plans prioritize flow and functionality, kitchens that work, primary suites with genuine privacy, and outdoor living spaces that feel like natural extensions of the home.
For builders, this translates into fewer field issues, cleaner details, and smarter engineering. For homeowners, it means spaces designed around real life.
But Retnauer isn’t resting on three decades of proven success. He’s pushing RBA Home Plans toward something the residential design industry has never seen: an architect-led plan ecosystem powered by AI, BIM, and automated design tools.
The vision is ambitious. Elevations and roof plans that update automatically with floor plan changes. Designs, previewed in 3D within seconds. Homeowners personalizing layouts through guided AI. The 3D model and elevations updating in real time.
“The future of home design is interactive, adaptable, and digital,” Retnauer states. “And we intend to lead that shift.”
RBA has already positioned itself ahead of the curve as early adopters of BIM-based design, TestFit, and AI visualization. The firm has implemented digital twin workflows, AI-assisted rendering, and automated feasibility studies. These innovations required training, experimentation, and cultural change across the organization.
The hardest part wasn’t the technology. It was transforming hundreds of past projects into a streamlined, searchable, builder-ready digital platform. Scanning, updating, organizing, and refining decades of work demanded time, vision, and persistence. But it laid the foundation for what comes next.
Retnauer’s broader mission extends beyond technological advancement. He wants to close the gap between custom architecture and affordably priced ready-to-build plans, making high-design, lifestyle-focused homes accessible to more families without requiring full-service architectural fees.
“Great design shouldn’t be a luxury item,” he insists. “It should be the foundation of every home.”
