SIDCO began in the months after the 2018 Camp Fire. One of our founders, a structural engineer raised in Paradise, came back to a chimney where her childhood home had stood. The engineering question that followed was disarmingly simple: why are we still building houses out of the same material that just burned?
The first prototype was tested at UC Berkeley in 2019 — a sandwich of galvanized steel skin, dense mineral-wool core, and a structural cementitious board, laminated to aircraft tolerances. By 2021 the assembly was patented. By 2023 SIDCO-ESP panels from MagMatrix were in production and our Pittsburg assembly line delivered the first permitted ESP home. In September 2025, a Class-3 wildfire pushed within three lots of that home. The neighbors lost everything. The ESP-built residence lost a single ceramic planter on the back terrace.
That single house changed the conversation. Today SIDCO licenses the ESP system to a vetted network of certified architects and builders across the Western United States. MagMatrix manufactures the panels; we certify and assemble the system. Our partners build the homes. The thesis hasn't moved: California is going to be rebuilt — and the way we build has to change with it.
