Practice Ideology

SAOTA, a leading firm of architects is driven by the dynamic combination of Stefan Antoni, Philip Olmesdahl, Greg Truen, Phillippe Fouché and Mark Bullivant who share a potent vision easily distinguished in their design. This, paired with both an innovative and dedicated approach to the design, documentation and execution of projects globally, has seen SAOTA become an internationally sought-after brand. SAOTA has a global footprint with projects on six continents. We have a clear understanding of the place of design in the world and how to deliver architectural projects in diverse markets. This success is driven by a design philosophy that connects function and form, and the pursuit of true architectural design to create appropriate solutions. The focus on achieving maximum value has also led to global invitations to design, build and create highly prestigious projects. The philosophy of practice is embodied in the spirit of enquiry that flourishes amongst its staff. This spirit not only guides the firm, but enables it to maintain its position as definitive designers in a highly competitive and fast-changing industry. Increased exposure to the global marketplace has seen SAOTA flourish as cities and contexts allow for infinite inspiration which can be seen radiating from the approach to design. SAOTA is also focused on using the most current computer technology in its design process, both to understand the design and to communicate the design to our clients. To this end we are world leaders in the use of Revit and have also developed virtual reality tools for use in our process.
