Mark Koester AIA

Associate Principal / Senior Architect


Mark Koester has over 25 years of experience leading the design of housing and hospitality projects located throughout California, the U.S., Asia and Latin America representing over 70 projects with a real estate value in excess of $5B and including more than 15,000 residences in mostly mid-rise and high-rise structures. He has received numerous design awards for these projects, several of which have been published. Mark’s focus is on sustainable, technologically advanced, amenity and service-rich housing with hospitality-like characteristics.

Prior to joining Page, Mark served as Chief Strategic & Creative Officer of a sustainable housing company based in San Francisco. Before that, he was a principal of BAR Architects in San Francisco for 13 years. Mark also has held positions at other firms in San Francisco, CA; Atlanta, GA and Portland, OR. During his career, he has held responsibility for all aspects of design, project and construction management.

Mark is fascinated by what the future holds for urban populations. He foresees that AI-enabled technologies will displace hundreds of millions of skilled workers globally over the next decade - dramatically changing how the current generation of homebuyers will earn a living and the type of housing they will need.
