This ADU is the first ICCF, or Insulated Composite Concrete Form, structure in San Diego. ICCF Building Material from The Perfect Block are lightweight forms made from 100% recycled styrofoam, stacked and filled with Portland Cement to create a structurally sturdy, fire-resistant, and highly-insulative building. The fire resistance played a very important role as the property is adjacent to one of San Diego’s many canyons and an additional fire risk comes with this terrain. Aside from the ICCF construction, the property features rainwater capture, a high kW solar system, and low flow plumbing fixtures. And goats!
