Costa de Leon is a provider of design  services based in San Luis Obispo, and owner of rental properties in San Luis Obispo, Pismo Beach and Grover Beach. 

With influences rooted in the styles of Frank Lloyd Wright, pre-Columbian, Mediterranean and Southwestern architecture, Costa de Leon designs have a unique, identifiable look, ranging from a traditional Spanish home in downtown San Luis Obispo, a Baja California Resort in Pismo Beach to the Mayan hacienda which serves as Alex deLeon's home and studio.

Regardless of style, the fundamentals are always there; proportion, the interplay of solids and voids, and design motifs which all contribute to the feeling of being in a unique space.

Alex deLeon holds a Bachelor of Architecture degree from Cal Poly, SLO, as well as a General Contractor’s license. Alex is semi-retired and now only takes on design projects for custom homes or unique multi-family projects in San Luis Obispo county.
