The Murphy Desk is a great collapsible workstation. The space-saving design hangs from the wall and opens to reveal a small storage area behind the door and a table top when folded down. When closed, the Murphy desk transforms into a chalkboard or corkboard - the choice is up to you. Create a home office when you need to and hide it after you've finished to make room for company.
An ingenious Victorian Metamorphic Combination Table, Desk and Chair (shown open and closed above) was made of oak around the 1850s, after a design by Stephen Hedges. Other similar examples are housed in museums in New York and New Orleans.
