Ours is in quaint Emmaus PA, and is a rambling place, which has suffered more than it's fair share of add-ons and improvements.
The "original" house was built sometime in the 1700s, and is stone. 14" walls, and was originally one room, as far as we can tell, one floor, with a walk-in basement. It looks like there was a porch off the back that had a summer-kitchen in it, based on some of the stubs left in the walls and smoke marks on the stone.
Around 1860 (when it was deeded), they put on a second floor, and built a room off the back running the full width of the house, by 18 feet deep, all in brick. (Which makes it _really_ interesting running anything from the second floor down to the first!).
Then, in the 1960's, they added _another_ addition, stick built, off that, that is a single story, with a small room, huge kitchen, first floor bath, and first floor laundry.
Just to add to the fun, the entire place burned out and was redone in the 1920's, so it's all thick solid hardwood, and mission/stickley trim.
One of the stone rooms still has the original plaster on the walls, and the rest of them have been exposed, with a granite chair rail/plate rail installed, and beadboard wainscotting from there down to the floor.
It's a very "castle" feeling, but quite chilly in the winter.
I'll post pics when I get some good ones. I have photographed everything _but_ the house.
