LEJARRAGA STUDIO is an Oakland-based architecture and installation firm founded in 2009 on the belief that a diversity of collaborators creates serendipity. Led by principal Ines Lejarraga, Lejarraga Studio is a nimble, boutique firm that assembles the best team for your project, drawing from a pool of collaborators that have a multitude of specialties including food service and retail, high end residential, office, and multi-family housing. Our collaborative approach allows us to offer a wide range of services with the in-depth knowledge of a much larger firm, providing the greatest value for your home or business.



Lejarraga Studio blends art with architecture through material exploration to create beauty.

Our work in installation art, furniture design, and lighting design serve as design studies that influence the larger work. Working closely with contractors, fabricators and artisans allows us to push the design forward by better understanding material possibilities and the talents of each craftsperson.
