Due to Monroe’s prolonged absences—Washington, France, England—the
development of the estate was delayed. Jefferson, and Monroe’s uncle,
Joseph Jones, Chief Justice of Virginia, had oversight of planning and
building. The exact date of the moving in is given in a letter from
Monroe.
“November 22, 1799. I was yesterday at Monticello, where Mr. Jefferson
informed me he proposed a visit to you ... I told him it would ...
immediately appear throughout the nation. He declined the trip ... in
the persuasion an interview might be had, by your making me a visit,
in my new home, to which I move tomorrow.” _Writings, Vol. III, p.
158._
