The crawlspace beneath an existing two-story residence in the Berkeley hills was excavated to become an unlikely new home studio for the artist. A new exterior stair provides access to the backyard and a private studio entrance. Tall 11' high ceilings provide necessary height in the studio. An 8' high sandblasted corner glass entrance diffuses the western sun and tall corner windows bring in controlled natural light. A long clerestory window captures the maximum northern light while providing interior space below for drawing and exterior space for the new stair. A new deck over the studio provides a walkway to connect to an existing rear deck with views to the bay.
