I am a fan of historical preservation, but even I realize there comes a time to let things gently go. The time to preserve the cabin on Fifth Street was 20 years ago. It is now both a public safety hazard and pretty much a pile of historical termite droppings.
However, there is still some hope for preservation of a sort. Not all structures can remain forever, but the legacy can live on. If there is any remaining sound wood, and that is a big if, how about we carefully dismantle those pieces and incorporate them into the new house? Just a small section visible from the sidewalk and a plaque describing the significance would do. Ron Hemby built our house years ago, and other than having the audacity to go on his honeymoon when our second floor was underway, did a wonderful job. I am certain he can include some of the logs in the facade of the new house.
In addition to the above, any remaining small pieces could be cut up and offered for sale to the community, thus helping Habitat build more houses. After all, Habitat for Humanity exists to provide housing for our community and not termites.
