This is a solid wood two panel interior door, the kind you commonly see on bedrooms in apartments.
You can use this door for its original purpose, a door.
Or you can use it for a wide variety of craft projects. I've seen all these over the years and many are amazing. There are so many furniture and other uses for common interior doors there are books on the subject. See screenshot.
