The architect owner, George Maxwell, and Mother nature created this not-so-big house with a gigantic upstairs home office, on spectacular one acre lot in a smart neighborhood, set into the bedrock of Mt.

House looks substantial from street and has Insulated Concrete Forms with two layers of foam insulation R-50 and concrete shingles on roof! It will last for eons!!! FEMA - Unknown Restrictions: Yes
