5 bedroom, two story home of 5600 sq feet but was designed to also be an inconspicuous fort with firing positions, cleared fields of fire, and a 1200+ sq ft bomb shelter under it all.
The walls have a brick facade covering a double row of cinder blocks filled with rebar and sand/gravel. The bomb shelter had 2, possibly 3 entrances.
It provides an interesting walk around.
i is just what i've always dreamed of doing for my own home, right down tot he brick facade(though i wanted reinforced solid concrete underneath instead of cinder blocks).
