The cellars of my house date back to around 1000, and gradually, the higher you get, the newer the floors are. The roof is C19. The front facade was once removed and replaced, I guess around C18. We still have the sockets and the pipes for gas light, though, of course, they've been superceded by electric wire, three times at least. It's still a pretty good place to live :-)
