Murphy bed idea for guest room, but add second "foot" that turns into desk further down the bed. Store work items and craft items in cabinet. Also, embed lights in top "foot," to shine down on desk, just like ones that shine on bed.
For 'you-choose-everything' kind of storage, look to IKEA PAX fitted wardrobes! You choose it all, from the size to the color and the style. Add IKEA KOMPLEMENT interior fittings to the inside so every shoe, shirt and scarf has its place.
