I have a small unit that I live in and one spare room which is an office, come junk room, come storage room, come guest room. I had previously had a sofa lounge/futon in the room but it took lots of space. After a trip to Ikea and a generous gift from my parents the room is now much more functional and funky. I spent much of the morning working on creatively reorganising space in the room and adding some splashes of red - which seems to be creeping into much of my decor these days.
The photos show what my results were.
