Hang Nga Guesthouse, Crazy House, Đà Lạt, Vietnam

The five-story-high guesthouse has generated a great deal of attention and controversy since its inception, with reactions ranging from criticism and derision to open admiration. The house was dubbed the "Crazy House" by early visitors, a name which Dang soon adopted for the house herself.
Visitors have generally responded positively to the house, describing it as "brave", "brilliant", "quintessentially cosmic", and lauding Nga for her vision and dedication to her work. One French tourist commented as follows:
“Thanks for showing me the meaning of life. The fairy tale house took me back to my childhood, to when things were pure and natural.”
Local authorities, including the People’s Committee of the city of Da Lat, opposed Nga's work on the house for many years, rejecting her proposals while citing concerns about its ad-hoc character, its lack of formal aesthetic, and its structural integrity. With perseverance—and private funding from friends and family—Dang was nevertheless able to further develop and refine the house, and was eventually able to convince the national government in Hanoi to endorse her work, allowing her to continue building without restrictions.
