I have a problem. I have many books and reading materials accumulated from my courses, which easily fills up 20 empty A4 printing paper boxes. Currently, I'm using some old boxes of different sizes and colours, and so my room looks like a storeroom.I'm thinking of organising this mess and making the room look cleaner.

Given the size of my room my first thought was to get a storage bed, and shove all those boxes under my bed frame to maximize the use of the empty space beneath my bed, which probably will not be used anyway, and to reduce the number of storage cabinets or racks required. But according to feng shui, it's a taboo thing to do. So I have to keep the space unused.

A second problem is finding proper furnitures to store these 20 boxes of books/documents/papers. I already have 2 book cases from IKEA, which are overloaded and the panels bent in the centre for some. To provide storage for these 20 boxes, I would probably need at least 2 half-height (waist level) storage cabinets or 1 full height. Also, how do I design a storage system that is modular, cost effective and suitable for bedroom?
