I have found it. This is the house in question, once in the middle of nowhere and now on heavily trafficked Route 9. I learned the story weeks ago over breakfast. Locals have it that it was built by a jealous sea captain. When he could not keep his wife contained in town, chastity belt non-withstanding, he moved her out into the middle of what was then nowhere and placed a chair on the roof so she would be comfortable as she awaited his return….some things never change.
