So, I bought my first house, which is awesome. I have a simple question about adding a door to an existing frame. I have a Rec room in the basement which has a shitty plastic accordion sliding door. I'd like to replace this with a proper closing door, and am wondering what I have to do? I'm a total noob at home renos so I have no idea if I have to replace the whole frame or if I can just add something to this one to allow it to adapt a door. (Hinges, latch, etc...?)
*I may even be interested in doing a double door on either side of the frame as I'll be playing music in this room so the better noise blocking the better.
*Pics attached, advice welcomed.
