IKEA Hackers: Expedit play stove - use contact paper and electrical tape to turn a bookshelf into a play stove. Great for limited space! IKEA also sells doors for this, so you could easily make an oven or fridge in one of the compartments too!
ikea bookshelf with reused futon - into great window seat! I could see putting casters on this too and making a rolling bench storage. Also, building this out of pallets and a walmart clearance outdoor cushion?
