Born and raised in Colombia, Santiago moved to Providence, Rhode Island, to pursue his passion for design, graduating from the Rhode Island School of Design in 1999 with degrees in Architecture and Fine Arts. After relocating to Los Angeles, he honed his craft at small architecture firms specializing in high-end custom residences and boutique commercial spaces before founding his own practice in 2006.

Custom improvements can make a home more functional, cohesive, and personally expressive. Rather than applying generic updates, the design responds to the property, household routines, architectural character, and long-term goals. A coordinated approach can also connect renovations, interiors, cabinetry, furniture, and built-ins so the finished environment feels intentional and enduring.
