There is a good writeup about the First White House of the Confederacy on Wikipedia. It includes a floor plan. On the left as you walk through the front door are the front and back parlors, then the dining room. On the right are Mr. Jefferson's bedroom, then Mrs. Jefferson. The one-story extension behind that is a library. In 1919 the White House Association of Alabama bought the house and moved it roughly nine blocks to its current location, where it was renovated. The landowner of the Bibb Street location did not want to sell the property, which is now all commercial.

Lots of Jefferson Davis homes: the one pictured here is the "First White House of the Confederacy," where he lived briefly in 1861 before the Confederate capital was moved to Richmond. It has been restored.

Also on the rebel visiting list (and pictured below):

Rosemont Plantation, Wilkinson County, Mississippi, Davis's childhood home;

Brierfield Plantation, Davis Bend, Mississippi, built by Davis in 1847 and his home before being chosen Confederate President;

Beauvoir Estate, Biloxi, Mississippi, his last home--though he was headed to Brierfield when he fell fatally ill in 1889.

In addition: the Confederate Executive Mansion in Richmond (where Lincoln sat in Davis's chair on April 4, 1865), and a prison cell in Fort Monroe, Virginia.

The house might not have been at Washington Avenue in 1906, but based on this site, that's probably an accurate depiction of the house for that year. https://encyclopediaofalabama.org/article/first-white-house-of-the-confe...
