The Probem was that the new cabinet should provide as much stowage as possible, but it also needed to fit under a sloping ceiling.
So after a lot of thought and research I went to Ikea, bought myself a childrens closet called Sundvik.
I then made & added two more shelves and some boxes, which was both cheap and easy.
making the new shelves. I wish I had a workroom ;)
adding brackets to fix the new shelves
Finished ;)
