Oldest that I've owned is my current one in western NC, it's built ca. 1945.
House that I grew up in, in the outskirts of Bethlehem in upstate NY, oldest map showing it was from ca. 1769 IIRC.
The house was originally a 2 room stone house with hand hewn beams and t&g boards with a shake roof, in the early 60's my great grandfather, a carpenter for the D & H railroad, built an additon that doubled the size.
The old part was awesome, the beams were easily 16" square, the walls were field stone, 2 feet thick packed with mud and horse hair, most of the window panes in the 3 8 x 8 windows were still that old wavy, bubbly glass. Many places the mortar has cracked out and many birds nested in the walls, my bedroom was on the second floor, it used to be the hay mow, but my GGF raised the roof to make the second floor, and on summer mornings, when they started singing before sunrise it would drive me nuts.
