wardrobe and shoe rack

I need to instal a customised shoe rack that blends in with the walls (attached a pic of the space in the hallway), and a 3-door wardrobe (pic of old one attached; there is also a pic of the space where the wardrobe should be installed). I am looking for something sleek, with clean lines and unique. I am not looking for classical English countryside style, I like to see interesting solutions, not recycled old ones. I am open to suggestions, especially regarding the wardrobe which must be built around a boiler exhaust pipe and electrical panel and have no back panel on one side to allow for an opening in the wall to access a storage space behind the wall. The shoe rack may be simple in concept but I would like something stylish and practical, where the space is maximised, wall mounted (floating), perhaps with some space to store keys (not mandatory but a nice to have)
