Boeing 727-200 House
Bruce Campbell purchased this high altitude home in Hillsboro, Oregon, in 1999. Campbell, an aviation enthusiast, spent $100,000 on the decommissioned military aircraft, not including the $220,000 he shelled out to renovate the interior. Campbell made note that the structure is “highly fire resistant and provides superior security.”
