Cedar Ridge Estate — completed residential project, Sonoma, CA 2023

The Challenge

The program included a wine cave requiring excavation into a basalt ridge. Structural engineering for the cave required custom shotcrete specifications to accommodate the irregular basalt face. Separately, the county's wildland-urban interface (WUI) requirements mandated Class A roofing, non-combustible exterior cladding, and ember-resistant vents on all five structures — constraints that clashed with the design's preference for natural cedar siding.

Our Approach

For the cave, we partnered with a specialist tunneling subcontractor and designed a hybrid: the entry portal in gunite-formed concrete, the interior gallery in board-formed concrete with integrated LED uplighting. For the WUI compliance, we spec'd a thermally modified cedar (Accoya® grade) that meets Class A ignition resistance while maintaining the visual character of raw wood. No design compromise.

The Outcome

This illustrative outcome pattern reserves room for a verified change log, commissioned environmental readings, and properly linked editorial coverage.
