A wood-framed building, similar to many other World War II period “H-plan” buildings, it served as guest quarters to a number of dignitaries during the top-secret Manhattan Project, including Enrico Fermi, Robert Oppenheimer and General Leslie Groves.

On December 18, 2009, the Oak Ridge Revitalization Effort, a local nonprofit organization, announced that it had purchased the historic property.

The Oak Ridge Heritage and Preservation Association (ORHPA), a group concerned with protecting the city's history, them began working with ORRE to develop a new non-profit organization that would focus entirely on restoring the Inn.

In November 2015 the building re-opened as a senior living center, after an $8 million renovation via Dover Development.

Shortly after the book was published, this pool, which did exist prior to the building's conversion into an assisted living center, was drained and filled in with dirt.
