Here is a really interesting idea, a pot house. Its a gigantic vase that has been configured to have a table and bench, that can convert to a bed.
Here is what Shedworking says about it:
The genuinely unique African Pot House from Dingley Dell (featured earlier today on the BBC’s Working Lunch) is a shedworking atmosphere with a difference: it measure 3.5m x 2.5m and is made from light but sturdy Fibrostone. Though designed to seat half a dozen people for dinner or cocktails, it would make a fine garden office – I can see Shedworking’s own Garden Show Editor Emma Townshend for example using it as a writing studio.
The table can be recessed into the bench, while the basic model has a tented ceiling, rustic matching cushions and curtains and a suspended candelabra. Window positions can be altered to suit the buyer’s tastes. The Deluxe model comes with full electrics including warm up under floor heating built into the walls, thermostat control, and light fitting in the roof.
