This is the house that Nate Saint built, right across the street from the airfield.
"The house as originally built at the MAF base soon proved to be too small for the numbers of people who came to Shell Mera on the way into or out of the jungle"
"The brown-stained hosue had to be expanded until it became a sizable building that provided sleeping quarters for twenty or more."
"Marj and Nate took great pride in the rambling home that looked much like a Swiss chalet, with wide eaves that protected against the constant jungle rainfall and gutters that caught the water for household use."
From "Jungle Pilot" by Russell Hitt, a biography of Nate Saint.
