Start by measuring the height and width of the wall before it begins to slant. That's the tallest, widest stand alone wardrobe that will fit. Once you begin shopping and checking sizes and styles, you'll see you'll able to fit wider but not taller units.

If you post dimensions of the area and photos of the other walls, posters will be able to suggest more specific ideas for you to consider.

it the main entrance, as you can see on the first picture in the left corner.

It’s a perfect spot for a Tansu cabinet.

Design with height on left for your area.

I'm assuming your landlord will allow you to hang the rods but if not, use tension rods instead which don't involve making holes in the wall.

You could duplicate the Tansu system with cubes and other cabinets from IKEA to save money and add a coat tree and short lockers for the short wall.

If you can't do a built in, but you can hang things, you might try something like this from a design of ours. Try hanging storage boxes above the coat hangers, then add a bench with storage baskets underneath. If you have room after, you might be able to add some sort of larger storage for various other items to the right or left.
