Storage in an awkward space.

[CatAmongThePigeons]

My sons wardrobe is in a really awkward space, under the attic staircase and I'm finding it increasingly difficult to use the storage that's in there already but I'm in need of inspiration to make good.

To make it more complicated, it's fronted by floor to ceiling sliding doors so there's a part of the wardrobe that's practically impossible to reach unless you climb in.

My word, that is really badly worded. Sorry!

What are you asking? Not sure what "make good" involves.

I'm finding it difficult to picture what you mean, but could you do without the doors and shelve the awkward area instead? Or make it into two spaces so that one part had a door and the other was shelved?
