Welcome to Our Studio
At the heart of our architecture is a commitment to creating meaningful connections between modern life and the natural world. We design spaces that inspire, restore, and energize—places where people feel both grounded and uplifted. ​​
Founded in 1996 in the Hollywood Hills, our studio was born from a love for the California landscape and the creative spirit of Los Angeles. Inspired by the legacy of mid-century Modernism, we embraced a collaborative, client-centered approach. In 2000, we returned to our Bay Area roots, and our Mill Valley studio now serves clients across California and the West.
​
Seamless Integration of Inside and Outside
​
Our designs are shaped by timeless principles: a seamless flow between indoor and outdoor spaces, light, simplicity, and natural materials. We focus on creating environments that balance beauty with functionality—spaces that enhance well-being, comfort, and human connection.
​
A Collaborative Adventure in Design
​
We believe every project is an adventure, an exploration of new ideas and creative solutions. Our collaborative process involves working closely with our clients and a diverse team of landscape architects, engineers, designers, and skilled builders. Together, we shape spaces that are deeply connected to our clients' aspirations and the unique spirit of each site. By embracing the inherent challenges of a project, we transform them into design opportunities, resulting in spaces that feel timeless, personal, and inspired.
​
​Sustainability and Balance
​
We are committed to designing with sustainability in mind, prioritizing a clean energy lifestyle where electrification, restoration, and regeneration are central. Our work promotes harmony with the environment and enriches the lives of those who inhabit it.
Building Meaningful Connections
Architecture has the power to strengthen relationships—whether within families, communities, or between people and their surroundings. Our designs reflect the values of our clients, creating spaces that foster meaningful connections and enrich everyday life.
We look forward to hearing from you...

ANTONINA MARKOFF, LEED BD+C
Principal
Antonina brings a unique blend of inspiration, creativity, and technical expertise to every project. She works closely with clients to craft architecture that is deeply connected to both the people it serves and the environment it inhabits. Antonina is known for her ideas and attentive, responsive approach, guiding each project from concept to completion with an agile focus on collaboration and thoughtful design. In her 36 years of professional practice Antonina has explored design across a wide range of scales, programs, and disciplines, including residential, commercial, planning, landscape, furniture, interior design, and the arts. To all she brings a dedication to detail and insight into natural materials and technology. Antonina’s design is shaped by her curiosity, her passion for teaching and learning, and her involvement in community and state level policy advocating for a healthy planet. Guided by her strong connection to the natural world, Antonina advocates for a sustainable relationship between nature and architecture. As a LEED AP BD+C, she actively addresses climate change through her leadership roles in the Climate Reality Project, within which she co-founded the California Coalition of Chapters, and in Climate Action California, where she’s as a board member as well as a founder. Her commitment to green practices is also evident in her past contributions to the Hillside Development Advisory Committee in Mill Valley, her role developing the Mill Valley Design Review Handbook and on the Mill Valley Planning Commission. Education has been a cornerstone of Antonina’s career. For over a decade, she taught architectural design, drawing, color theory, and building science at leading institutions including USC, Cal Poly Pomona, and Art Center College of Design. She co-taught with architects Pierre Koenig and Paul Murdoch, led the USC Second Year Studio and mentored the next generation of designers. Before co-founding Markoff Fullerton Architects, Antonina gained invaluable experience working with leaders in architectural theory and practice such as Peter Eisenman, Meier and Partners on the Getty Museum, and Skidmore, Owings & Merrill in Los Angeles. These experiences helped shape her rigorous and innovative architectural philosophy. A lifelong passion for architecture ignited at an early age, Antonina grew up in a family that embraced hands-on home remodeling and cultural exploration across Europe. Her education in design includes studying French at the University of Tours, painting at the Instituto Lorenzo Di Medici in Florence, and architecture at the ETH in Zurich. In her free time, Antonina can be found backpacking in the High Sierras, where she draws inspiration from the bold architecture of nature itself. Antonina holds a BA in Architecture from Yale University and a Masters in Architecture with honors from Harvard Graduate School of Design.
