About Topanga Architecture & Design

Geoff Sheldon

Chief Architect

Geoff grew up back east and started architecture classes in High School at one of the only high schools in the country to offer architectural design. (School Without Walls, Rochester, NY)

He studied architecture in England and later received his architectural degree at the University of Southern California. He focused on how to design for utilization of passive solar and other natural design functions.

Sheldon went on to work for a developer of medical buildings and was involved with several high-end commercial design firms. He obtained his contractor’s license and ran a construction company for 10 years. After working for several significant architects developing single family homes in Southern California, he obtained his own state license and became LEED Accredited by the United States Green Building Council (USGBC.) He has practiced architecture independently since 2008.

Sheldon’s experience allows him to bring a focus to optimizing architecture for natural, safe and efficient building systems and integrating them into a well-designed whole. His background as a contractor gives him the ability to recognize and understand cost and construction issues to make sure a project functions well and is the best use of construction dollars.


Roxane Berger

Interiors & Lighting Designer

Roxane’s interest in her client’s preferences for day to day living, entertaining and partners with you to create interior spaces that go far beyond the ordinary.

We live in exciting times for lighting design. With new energy saving technologies we are able to design spaces to have different mood settings. Your rooms can do “double duty” – bright and conducive for working on a hobby or warm and inviting for conversations. Light is an element of art and we can employ its use to enhance color, texture and form of architecture.

Roxane received her BA and MA in painting from CSUN. She is a C.I. D. (Certified Interior Designer) who educates you through the process. She is an adjunct professor at California State University, Northridge teaching lighting and other interior design courses.

Her art background and expertise in lighting design ensures that your project will look beautiful day or night, incorporating daylight and control systems. Her clients will have the ability to have different mood and task settings in the way they wish to control the lighting design.
