A boutique design studio serving San Francisco & beyond

At Kate DeWitt Design we believe your home should tell the story of who you are and the beautiful life you’ve lived!

Our aim is to create spaces that make you smile the moment you walk through the door. Whimsical yet elegant, playful yet refined. Every room should feel like a little bit of magic.

KDD works with clients to craft homes that feel like an authentic representation of them. Your space should reflect your unique journey, your treasures, your dreams made tangible.

Working from my seaside studio in Sausalito, California means coastal magic flows into every design. The light, the colors, the textures of this place inspire all the interiors I touch.

I collaborate with clients throughout Marin, San Francisco, the Bay Area, and beyond.

Every project begins with understanding your story, then we weave that narrative into walls, textures, and light. The result is a home that whispers “this is exactly where I belong.”

client love notes

  • Working with Kate was a joy! I thought I knew what I wanted but she expanded my perspective and introduced me to new concepts, while still focusing on my personal style. She was not only a good listener assessing my style and hopes for the project, but she was also responsive, communicative, and accommodating. Kate's level of detail, creativity, and concierge style of coordinating the entire design process exceeded my expectations.

    Annie | Design Client

  • Working with Kate is a fun, creative collaboration. When I hired Kate, I'd moved into a very nice place that I wasn't really relating to. Now, thanks to Kate's placement suggestions and the things we worked together to buy, I open my door and feel happily at home. She brings a fresh, refined and insightful sense of taste and style - while being mindful of the client's budget. Best of all, she is a delight to be with so, what can be a stressful experience, is fun.

    Linda | Design Client

  • We’ve absolutely loved partnering with Kate on various product launches and campaigns. Not only is she such a delight to work with, but truly understands our brand and brings our products to light in a creative yet meaningful way.
