The house is 100 years old, but there have been a few modernizations over the years. That drdop ceiling and panaling was put in around the mid 70s or so. I actualy like the drop ceiling because it gives me a place to run cables, but the upstairs bedrooms are pretty true to the victorian period, as the exterior of the house. Also, a room was added on in the mid 60s. My diningroom use to be the kitchen, then a bigger kitchen was added in the 60s, and I remodeled the kitchen about 3 years ago. Also, the bathroom use to be the pantry, because this house was originaly without indoor plumbing, and electricity. It was heated by a coal fired furnace.
So yes, it has been modernized, and as much as I love the oldness of it, the drop ceiling does afford me the convenience of being able to run my cables. But I did poke my head above those tiles once, and there is a true victorian style ceiling and walls there.
