In this episode of Not A 'Licensed' Architect, Stefani Thatcher sits down with David Holtzclaw, principal of Transduction Technologies and a mechanical engineer specializing in building science and high-performance homes.

With a background in aerospace and biomedical engineering, David brings a unique, science-driven perspective to residential design—challenging common assumptions about comfort, energy efficiency, and how homes actually perform.

Together, they unpack why many homes that look great don’t always feel great to live in, and how designers can bridge that gap. From window placement and insulation strategies to HVAC systems and moisture control, this conversation breaks down building science in a way that’s practical, approachable, and directly applicable to your projects.

If you want to design homes that are not only beautiful—but comfortable, efficient, and built to perform—this episode will change how you think about your plans.

What You’ll Learn

• Why comfort—not energy efficiency—should be your starting point• How the building “shell” drives 60–80% of heating and cooling performance
• The biggest mistakes that lead to mold, drafts, and uncomfortable homes
• How window placement and orientation impact both comfort and efficiency
• Why tighter homes require controlled ventilation—not “breathing”
• When systems like heat pumps and radiant heating make sense• How to balance aesthetics, budget, and performance in real-world design

Every beautiful home is built twice — first on paper, then on-site. But what happens in between those stages is where most projects fall apart.

In this episode, I’m joined by Kimberly Parker, founder of Kimberly Parker Design and creator of Four Stripes, a new app helping design teams stay aligned from concept to construction. With 15+ years of experience in luxury residential projects, Kimberly shares how strong systems, clear documentation, and professional respect between trades can make or break a build.

Her approach flips the script on traditional design. It’s not just about creativity — it’s about communication, precision, and advocacy. Because when your design packet runs 50 pages deep, you’re not just handing off drawings… you’re leading a process.

What does it actually take to design and build your forever home — without losing your patience (or your mind)?

In this episode, I’m joined by a former client, Mandy Wilkinson, a homeowner who spent 2.5 years turning her Pinterest-perfect colonial dream into a real, living home. From navigating COVID delays and truss troubles to rethinking design decisions mid-build, Mandy shares the truth about the emotional, financial, and creative journey behind a forever home.

So why does her story matter? Because behind every “dream home” is a thousand micro-decisions — and knowing how to make them (and when to ask for help) is what separates a beautiful build from a stressful one.

🏠 Designing for Longevity:Why thinking ahead — wider hallways, single-level layouts, and smart storage, can make your home functional for decades.

🏠 When to Call in the Pros:

What happens when builders and designers stop working in silos, and start building together?

In this episode, I’m joined by Garrett Greenhalgh, owner of GPD Builders in Cache Valley, Utah, whose approach to custom homebuilding flips the traditional “us vs. them” dynamic on its head.

From growing up on job sites with his dad to leading a respected custom home company today, Garrett’s story is a masterclass in collaboration. He shares how clear communication, trust, and mutual respect between builders and designers don’t just make construction smoother, they make homes better, clients happier, and teams stronger.

So why does this matter? Because too many projects fall apart not from lack of talent, but from lack of alignment. Garrett reveals what it looks like when everyone’s on the same page — and how that level of teamwork becomes your biggest competitive advantage.

What really defines a beautiful, functional home?

When most people think about building their dream home, they obsess over finishes — countertops, flooring, paint colors, lighting fixtures. But here’s the truth: finishes are the last 5%.

In this episode, I’m joined by Liz Powell, owner of Liz Powell Design, whose work proves that true design success starts long before you’re picking tile and paint colors. With decades of experience balancing function, flow, and timeless aesthetics, Liz shares why a strong architectural foundation is the key to every stunning finish that follows.

So why does this matter? Because too many homeowners get caught up in surface-level design choices, only to realize later that their home doesn’t work the way they imagined. Liz’s perspective reframes the conversation — reminding us that great homes aren’t styled, they’re designed.

💡 What You Can’t Miss:

🏠 Beyond the Pretty PictureWhy a home that functions beautifully is always more valuable than one that just looks beautiful.

🏠 Trust Over TrendWhy building trust with your designer matters more than chasing Pinterest-perfect ideas.

🏠 Avoiding Costly MistakesThe real risks of focusing on finishes before getting the architecture right.

If you’re dreaming, designing, or already building, this conversation will shift how you see your home — and why architecture is always the true starting line.

🎧 Hit play to rethink what “good design” really means and how to get it right from the ground up.

What does it really mean to be a design advocate in residential architecture? 🏡

In this episode, I’m joined by Jeff Fry, founder of Fry Design Company, who has spent decades raising the bar on what custom home design should look like. From pioneering CAD and BIM in the ’90s to running his own firm today, Jeff shares why clear, comprehensive plans matter — and how being an advocate for clients sets great designers apart from the rest.

So why does this matter? Because in today’s industry, too many homes are built from incomplete, 5-page plan sets that leave clients with confusion, delays, and costly mistakes. Jeff’s mission is to change that — one well-designed home at a time.

💡What You Can’t Miss:

🏠 The Industry’s Identity CrisisWhy the lack of clear distinctions between architects, designers, and draftsmen is hurting clients — and ideas on how to fix it.

🏠 Minimal Plans = Maximum ProblemsDiscover why builders often resist detailed plans (and why that’s a huge red flag for homeowners).

If you’re building, designing, or simply curious about what makes a home project actually work, this episode will open your eyes to the real value of comprehensive design and advocacy.

What can 31 years in the plumbing trade teach us about building homes that actually work? 🚰

In this episode, I’m joined by Clay Wengreen, a Navy veteran turned plumbing expert, whose career has spanned service work, large-scale construction, and running his own business. Clay’s story begins with learning steam propulsion systems in the Navy — and comes full circle to helping homeowners design kitchens, bathrooms, and whole-house systems that truly fit their lives.

So why does this matter? Because too often, plumbing is treated as an afterthought in design — leading to awkward layouts, code conflicts, and costly mistakes. Clay’s perspective shows us why details matter, and how good communication between homeowners, builders, and designers can make or break a project.

💡 What You Can’t Miss:

🏠 From Navy to New HomesHow military training on complex systems shaped Clay’s career in plumbing.

🏠Designing for Function FirstWhy kitchens and bathrooms need more thoughtful planning than just fixtures and finishes.

🏠 The Hidden Cost of Poor CoordinationHow missed communication between architects, plumbers, and framers leads to stacked bathrooms, tight plumbing walls, and venting challenges.

🏠 The Comfort of Radiant HeatWhy hot water radiant heating provides a different level of home comfort compared to forced air.

If you’re a homeowner, builder, or designer, this episode will change how you think about plumbing — not just as pipes behind walls, but as a critical part of creating a comfortable, functional home.

🎧 Hit play to hear Clay’s 31-year journey and discover why great plumbing design is more than a trade skill — it’s a craft that shapes how we live.
