Located in the Hayes Valley neighborhood of San Francisco, Sagan Piechota Architecture was formed in 1999 by Architect, Daniel Piechota and Designer/Developer, Loring Sagan. SPA commercial and residential projects can be found in some of Northern California’s most spectacular settings – urban, coastal and rural. By partnering with our clients and exploring new ways to think about what is beautiful and functional, we are able to create architecture that reflects an authentic sense of identity while remaining respectful to a particular environment.
