Chet Callahan leads an award-winning building design office in Los Angeles, offering services ranging from space planning and partial renovations to ground-up construction of residential, commercial, and institutional buildings.


Chet Callahan is a Southern California native and brings to his work a deep appreciation of the

region and its climate.  His design process begins with a careful study of each site’s unique

character in order to propose a sensitive addition to the existing-- built or natural-- landscape. The

character of the existing building, daylight, and natural ventilation are central to each building

project.  The project is further articulated through a collaborative process with the client, analyzing

each of the client’s needs to provide a unique, functional, and efficient design solution.  While

each project is developed within the parameters of client and site, the overarching principles of

open spatial configurations, indoor-outdoor living, refined detailing and craftsmanship, and passive

building systems are explored within each project.


Chet Callahan has been awarded the AIA Bronze Medal, a Spark International Design Award, the Interior Design Best of Year 2014  and Best of Year 2007 merit awards.  Chet’s work has been published in 200 Outstanding House Ideas, ARCH, Interior Design Magazine, Casa D, Architectural Record, and the Los Angeles Times.
