This car shaped house near Salzburg, Austria has got to be one of the most creatively designed homes ever! The Voglreiter Auto Residence was designed by Markus Voglreiter. He took a 70's style house and transformed it into a Beetle-esque 900 square foot, 3 story home for his family.
Years after creating his Auto Home, Markus designed a restaurant/bar with a very similar exterior! Read about the restaurant here!

It may be synthetic grass but this house is covered in it! The entire exterior of this Austrian house (designed by Reinhold Weichlbauer and Albert Josef Ortis) reminds me of something out of Wacky Wednesday by Dr. Seuss!! Staircases set where they are there only for looks, not function, extending out into open space. Windows on top of other windows but turned sideways. Pretty awesome looking though!

Have you ever seen those huge, concrete drain pipes and thought "Hey, those would make great hotel rooms!"? No? Well, Andreas Strauss did and he created a "hotel" with them. There are 2 Das Hotel locations; one in Austria and one in Germany. The rooms are incredibly minimal with just a bed, lamp and a skylight. The hotel is also unique in that the cost of a room is "what you want to pay". A different idea indeed.
