corner shelf with a curtain rail to create mini-wardrobe (New Marston OX3)

A triangular shelf with a curtain rail along the long side and a rail for clothes hangers perpendicular to it, also a couple of hooks on the short sides. The idea is to fit this in a corner at head height and create a mini wardrobe in an otherwise unused space. The shorter sides of the shelf are just over 60 cm long. As you can see in the photo, the wood that gets fixed to the wall is poking out of the triangle a bit, so this bit would need around 70 cm space on each wall. The top of the shelf isn't very pretty, but if you hang it high enough you'll never see that part ...
