Founded in 1906, ours is one of the oldest and most established architectural firms in California. 19six Architecture, formerly known as PMSM Architecture, first entered the architecture industry over a century ago when A.B. Higginson, an architect and designer in his own right, saw major flaws in the design and structure of local buildings and wanted to improve their quality. What began as a family business in Santa Barbara has since grown into an architecture firm known across California for their award-winning design excellence and commitment to community impact.
