The Crazy House; formally called Hang Nga Villa; was built in the 90's by a Vietnamese architect Dr Dang Viet Nga. Dr Nga was born in Vietnam; graduated at the Architecture University of Moscow in the 60's, then worked at the Building Design Institute in Dalat shortly after her return to Hanoi in the 80's. Her passion and desire to pursue her dreams had turned out to be a huge controversial in the community since the Hang Nga Villa was formed in a way to break the traditional practices by free volumes with free curves and structures. Instead of following the dependent classic principles in the arrangement of masses of straight lines and square planes, Dr Nga used spaces open on the four sides of the room to create the richness of the environing visibility. The Villa has ten different theme rooms at the moment charging from US$10 up to $45. There's no fan, no phone, no TV, no internet in rooms, but you'll survive don't be scared. It's a sight seeing spot as well as a mini guesthouse that you don't see it in any other part of the world. Some people might think that Dr Nga's idea was in fact inspired by Gaudi's architecture but far from the standard and quality to be recognized. But I'd say, dreams could be costly, yet people without visions are perished. At the end; who's in the position being justified
