About Us
How It Started
In 8th grade, the assignment was simple: build a structure out of paper. While classmates made houses, Dulcie was already pushing boundaries—sculpting imaginative, unconventional forms. Even then, architecture wasn’t just about buildings; it was about vision, artistry, and storytelling.
That instinct for crafting spaces that evoke emotion never faded.
After earning her stripes at one of San Francisco’s premier firms, Holt Hinshaw Architects—where she quickly rose to lead the residential division within two years—Dulcie founded Horwitz A+D in 2001. By 2003, she was designing for exclusive clients in Southern California, bringing bold, sculptural spaces to life.
“Sculpting poetic space can happen anywhere”
How It’s Going
Today, Horwitz A+D is known for creating emotionally charged landscapes—spaces that shape mood, spark imagination, and refuse to be ordinary. Whether it’s a home, a restaurant, or a retail space, every project is an opportunity to sculpt something poetic, immersive, and unforgettable.
We specialize in high-end residential and commercial architecture, with 60–70% of our work focused on bespoke homes, while the rest transforms retail and dining environments into spatial experiences that captivate.
Our clients don’t just appreciate our designs—they feel them. They tell us they love our creative energy, passion, and ability to translate vision into built form. They trust us to push boundaries while remaining deeply responsive to their needs.
After all, sculpting space isn’t just what we do—it’s who we are.
Our Team
Breeanna Karlin
Senior Designer
Breeanna first joined Horwitz A+D in 2009, beginning a path that led from the design studios of Woodbury University to the urban landscapes of Oahu. Her design talent gained early recognition, including the 2016 LABC Julius Shulman Emerging Talent Award and an honorable mention in the international Tiny House Architecture Competition.
She later expanded her expertise as a Show Set Designer with THG Creative, where she developed immersive environments across a range of creative disciplines. In 2022, Breeanna returned to Horwitz A+D—not as a newcomer, but as a design leader shaping the next chapter of our work. Her creative vision and thoughtful approach continue to elevate our projects and inspire our team.
We’re proud to have her back—and excited for all that lies ahead.

Ramon Ricafort III
Associate
Ramon Ricafort III joined Horwitz A+D in September 2024, bringing with him a uniquely diverse background that spans residential architecture, textile design, and even managing an auto body shop. A graduate of Woodbury University’s B.Arch program, Ramon thrives at the intersection of technical precision and expressive creativity. He’s particularly drawn to the graphic process of architecture—how sketches, diagrams, and drawings convey layers of story and intent.
Currently pursuing his architectural license, Ramon is deepening his focus on residential and mixed-use design solutions. His goal: to explore how thoughtful, context-driven architecture can better serve the evolving needs of Southern California communities.
