Looking at this house you could be forgiven for thinking the world had turned upside down.
Standing on a pointed roof and supported by steel beams in the attic, the house amazes neighbours and passers-by alike.
And inside the front door things are even weirder - everything from the bathroom to the fruit bowl on the kitchen table are hanging over head.
The 23ft-tall house has an upside-down kitchen, bathroom, living room and bedroom. It was also built on a slight incline to challenge the viewer's perspective still further.
The men spent months to perfect every little detail and even took to needle and thread to keep the bed linen in place. But Mr Splettstößer said their pains were worth it.
'It's a nice feeling, so to make something unique,' he said.
The zoo owners hope the house will give visitors a 'totally new perspective on a familiar view.'
The 'crazy house' is reminiscent of a home described in Roald Dahl's children's book The Twits. In the children's story a group of monkeys are forced to hang upside down by their owners. They have their revenge by sticking all of the couple's furniture to the ceiling and convince them to stand on their heads.
The 'crazy' house was thought up by Hamburg investor Dirk Oster. He will open it to the public on March 30.
