Specifically the type of architecture Jefferson championed: classical, symmetrical, purposeful architecture.
And one of the best books that details Jeffersonian structures in and around Charlottesville, Virginia, (and in my opinion a book no design-loving Southerner should be without) is a vintage book called The Architecture of Jefferson Country. You can find copies here.
It was written by one of the most famous professors at UVA's School of Architecture, K. Edward Lay, and the entire book is fascinating but I've worn out the pages devoted to my favorite type of Jeffersonian architecture: the Tripartite house (example of the style shown below via the floor plan for Mountain Grove, a home which dates to 1803-1804).
Absolutely love it. So unbelievably efficient and beautiful.
