Hi, I’m Tanna. So glad you’re here! ✨
I’m the founder, owner + principal designer of TANNA BY DESIGN®, a full-service residential interior design studio in Tri-Cities, Washington. 🌿
For nearly 16 years, I’ve been helping homeowners create homes that are elevated, personal and most importantly … easy to live in.
Today, I’m especially passionate about new construction home design and the power of a truly connected design-build team.
I collaborate exclusively with a custom home builder, bringing interior design into the conversation from the very beginning. We work together on the details that matter …from layouts, architecture and materials to lighting, finishes and all those little moments that make a house feel like your home.
Because here’s what I believe:
The best homes don’t happen by accident. They happen when the right people are at the table from day one.
That means fewer costly mistakes. Smarter decisions. Better flow. More personality. And a home that feels beautifully resolved from the outside in.
Around here, you’ll find new construction inspiration, design tips, behind-the-scenes peeks, pretty things, practical things, a little bit of green 🌿 and plenty of “wait… THAT detail!” moments.
Whether you’re building a new home, dreaming about one, or simply love beautiful spaces…
Welcome. You’re in the right place.
This is TANNA BY DESIGN®.
Design the way you live. LIVE EASY.
