Since 1991, our innovative, sustainable, and creative approach has resulted in award-winning work throughout Northern California and beyond. We have extensive experience with San Francisco’s rigorous building review process, as well as numerous approval agencies in Sonoma County, the East Bay, and on the Peninsula. Additionally, we have completed out-of-state work in New York, Wyoming, and Oregon. Whether we are working with new or repeat clients, we are passionate about architectural design that fulfills their hopes and exceeds their expectations.

Our firm’s design philosophy is rooted in context – site specific, classic forms, with strong interior/exterior connections. The play of natural light is of paramount importance in our work, as are the unique challenges of urban infill, historic buildings, and green building strategies. Whether we begin with bare land or existing structures, our projects develop their character through careful interpretation and sensitivity to each client’s program, site orientation, context, and climate. MDa’s design process for both renovation and new construction is comprehensive, nuanced and collaborative. Our goal with every project is to bring warmth to modern design.

“MDA blends clean simple lines with an overall warmth. Too often, modern seems to equal cold, but Malcolm manages to make modern warm without compromising the aesthetic in any way.“

Malcolm Davis is a Bay Area native with an intimate understanding of regional building styles and climates.

Pat moved to San Francisco two weeks after completing his Bachelor of Architecture at the University of Southern California in 2009. Since, he has obtained his license and settled in the foggy Outer Sunset District with his wife. His attention to detail, appreciation of building materials and natural light compliment his ability to coordinate and collaborate with clients, contractors, consultants and Malcolm.

Julia is originally from islands outside Seattle, Washington. Since moving to San Francisco, she has been admiring the daily rhythm of the fog, the predictability of the plan, and the surprise of the section. She is interested in how architecture can layer the natural and the constructed to materialize the forces of its environment and remind us of the larger systems in which we are embedded. She appreciates the challenge of bringing light into the slim spaces of the San Francisco block and aims to engage with the specific circumstances of each project to make it distinct.

Raised in West Virginia, his rust belt roots inspired a love for duality; industry and nature, modern and traditional, form and function.

In his free time, you can find him wherever there is music, catching shows across the city or practicing his guitar.
