As Principal-in-Charge of Design, Mark Hornberger is responsible for the coordination and management of Hornberger + Worstell’s planning and design effort for all major projects, focusing on mixed-use, hospitality, multi-family residential, corporate office and higher education projects. In addition, he leads the permit approval processing and public review efforts of the firm.

Over the last two decades, Mr. Hornberger and his design team have completed over forty major projects. These designs are focused on sites across North America, Latin America, and the Pacific Rim/Asia.

Mr. Hornberger’s architecture consistently employs regional materials and geographically inspired forms to provide work environments, recreational amenities, lodging, dining, and meeting/gathering spaces. His gracious projects, with their focus on the relationship of the buildings to the landscape and cityscape, provide inviting access to scenic and city resources in a variety of urban and resort locales.

He combines his expert knowledge of mixed-use requirements with the firm’s regionalist sensitivity to context and materials. The projects derive their distinct identities from the thoughtful and innovative use of building materials and skilled local labor brought together with a considered use of advanced construction techniques.

The sense of place in his projects is heightened by an ability to achieve a seamless interplay between inside and out—his trademark “livable landscape.” He pioneered the design of outdoor function spaces and water features as integrated extensions of the architecture, allowing users and visitors to enjoy fully the unique climate, light and vistas of a particular region throughout the individual properties.

The success of his projects has won Mr. Hornberger the respect of his peers in the development and hospitality communities, where he speaks on design related issues for organizations such as the Urban Land Institute, Resort Forum. He has chaired the Design Awards Committee of the AIA California Council, and, from 1992 to 1994, he was Chair of the Architecture and Design Forum of the San Francisco Museum of Modern Art. He was Chair of the AIA Capital Forum, is a past Director of both AIA San Francisco Chapter and the AIA California Council and is current Chair of the AIACC Task Force on CEQA reform.

I came to architecture in a roundabout way: I taught English in Spain and worked on the trading floor of a New York investment bank before I ended up in architecture school. But these early experiences gave me a more nuanced view of the world, and have shaped my career in the years since. I love hearing a friend or colleague say “I had no idea!” when coming across one of our projects. After spending so many years focused on the details of a project, from design through construction, to step back and see the work appreciated is a privilege.

I loved watching my grandfather, who was a carpenter, use a simple hand plane to create these smooth rich colored wood cabinet pieces. When I decided to become an architect, it was due in large part to his influence.

Location can tell you a lot--not just about where a place is, but its people, its culture. I’ve been interested in maps and cartography for most of my life, and considering our projects through the specifics of their geography has always yielded helpful insights. A major part of what I do is presenting our projects to clients, so being as informed as possible about the context of the project is essential. How does our work reflect the culture, identity, audience, and other diverse factors that are important to the client? That bigger picture is what inspires my professional work.

I've always been an advocate of applying the creative arts to problem solving. Client design briefs often contain unique challenges and untested ideas, which require creative ways of evaluating, sorting and ultimately solving problems in sophisticated ways. Good design solutions usually satisfy a physical need while provoking delight and contemplation.

Growing up in Shanghai, I saw great change take place in the built environment surrounding me. Observing how architecture shapes a city and the lives of those living there, inspired me to become an architect. I would like to contribute to the design and development of these growing global urban communities. I feel that successful projects inform the success of future projects, building upon the things we learn and advancements we make.

I grew up in an American city amid well designed buildings and spaces created six decades earlier during a brief period of enlightenment by a race of people that had moved on. My interest in architecture grew out of the conflict between those interested in preserving and rehabilitating the old buildings, and those keen to convert them into above-ground parking.

I’ve been working in the field of architecture in the Bay Area since 1979. I find success in the moments when the drawings start to really communicate, and when, on the job site, I get past being the guy wearing a tie to the guy the workers know has the answers and paths to solutions.

Born and raised in the Central Valley, our family enjoyed many trips to San Francisco. In my travels I discovered that the Bay Area was a mecca for artists, designers and craftspeople. Moving here in 1990, I had the pleasure of finding a large community of people that shared my passion for the arts. Architecture, to me, seems to be the combination of art and engineering and I enjoy learning about the various aspects of the practice while contributing to a smoothly operating office.

Ultimately, a project is successful if people use it. Seeing one of our recent university projects seemingly always packed with students made it clear that the project had fulfilled its goals. My work is about creating spaces that people can experience, interact with and enjoy. I love the feeling of being able to point out a project to someone and say that I helped to create it.

The Bay Area’s diversity is a blessing, having been born in Vietnam and raised in Manila, I grew up in diverse environments, sparking my interest in architecture. After moving to the Bay Area over 20 years ago, I found myself engaged in an important role as a construction administrator for an architectural practice. My success is obvious when my team can focus on the technical details of their projects while I administer the day-to-day minutiae. Being part of a skilled, collaborative team motivates me. I consider myself the bridge between all project stakeholders, inspiring others and contributing to project success.

I am drawn to architecture because, through it, I can express my understanding of the relationship between building, nature, and people. I can use the process as a way of better understanding how other people think. There is so much to learn, but the great thing in this profession is working with more experienced colleagues, who offer input and encouragement to help navigate big challenges.

With both my parents being architects, from a young age I’ve always had an interest in and a connection to the profession. I chose to study and work in graphic design, and I am glad to find myself in a position where the two disciplines overlap. I came to the Bay Area from New Zealand, but I feel at home here. The city’s diversity and beautiful climate are welcoming.

It's important to find opportunities to be creative in everyday tasks. There's always a new way to look at a problem. It's easy to get caught up in the work and miss an opportunity to do something interesting, but when I step back and make myself try a more novel approach, I'm very often rewarded with a more interesting result.

I caught the architecture bug very early in life, having had the privilege of growing up in an historic area in New York dating from the mid-1600s with a rich architectural heritage. Successful architecture, in my opinion, resides in the details, from large scale in the planning stage to small scale in the final detailing of how systems and materials come together. Elegant, seamless detailing is my personal measure of success.

Virtual design and construction is the future of our profession and I am an active participant in its evolving role. A fully realized virtual representation of a design concept benefits all stakeholders of a project, allowing for real-time simulations in complex environments that were unachievable before. I strive to incorporate this approach into the projects I contribute to, and to cultivate a deeper understanding of and appreciation for virtual design and construction among my peers.

When I was a child in Japan, my parents worked with an architect who was a relative when they built their house. I was amazed how the architect seemed to transform our dream into reality. I studied architecture and became a licensed architect in Japan, and moved to the U.S. in 1999. I am motivated most by the sense of achievement I feel both in incremental progress over the course of the day, and in the outcome of the project in the long term.

I recently moved to the Bay Area from China. Years ago, I noticed how architects play a role in the happiness of others: even relatively small-scale projects like individual homes make a huge difference in the lives of others. I wanted to be a part of that process, and help make the world a better place.
