Your ideas needed

So the Armoire I was going to get is not right for my project, the doors slide back into the cabinet. and its not wide enough. I have a antique white armoire I could use but will need to find a place for the stuff in it. Our house has only two tiny closets, so the armoire it serves as a the main coat closet and catch all. I may still use it, since its deep enough and wide enough - although adding out to each side crossed my mind. so what I really need a triple cabinet if I can find one deep enough. I WILL BE cutting stairwells and doorways.
