Finding his lodging in the heart of the city uncomfortable, he removed to the rooms of Jacob Graff. Graff was a well-known bricklayer who had built his house on the outskirts of town but a year before Jefferson arrived. It's probable that Jefferson had to pay a little extra for the rooms as they came furnished. The Graffs lived in the house while Jefferson undertook his task. Situated on the outskirts of town, surrounded by fields and a stable across the street, the house provided Jefferson with the space and distance from the city he needed for his task.
Working from the Virginia Constitution as well as an extensive knowledge of political theory Jefferson wrote the document in under three weeks. An author at heart, Jefferson squirmed in resentment as the document was redacted during the final week of June 1776 by his fellow delegates to the Second Continental Congress.
The Declaration house exhibit includes a recreation of the two rooms Jefferson rented on the second floor. In it, one sees Jefferson's bedchamber including a tiny bed that makes it hard to imagine how the gangly Jefferson slept at night. One of the only original items in the exhibition is a key to the front door. Jefferson entertained other members of the Congress in the sitting room.
The original structure was torn down in 1883. Photographs of the site enabled the National Park Service to build a rather faithful recreation of the original building.
