French travel guide Hachette has also highlighted the “Crazy House” as a not-to-be missed hotel stay on any trip to Vietnam.

The house, occupying nearly 1,600m² on Huynh Thuc Khang Street, was completed in 1990 as a personal project by architect Dang Viet Nga. The controversial building once dismissed as “crazy” has now become a regular feature on tourist visits to the city.

The free-form undulating structure is quite unlike anything else in Dalat, let alone Vietnam. The house is constructed on a numerous levels with a naturalistic theme interpreted through concrete curves, twists and bends, giving it the appearance of an out-grown tree.

The interior is equally unorthodox, with almost every surface twisting, curving and running fluidly along the internal corridors, stairwells and rooms.

Mismatched windows give the impression of a fairytale house straight from Little Red Riding Hood, while stone tigers, bears, eagles, kangaroos and pheasants decorate the environs adding to the surreal environment.

The building has been dogged by controversy since conception with arguments centering on the structure’s insufficient architectural integrity, ad-hoc character and lack of formal aesthetic.

Nga shrugs off criticism, “Many people have criticised me, even my colleagues. I don’t blame who don’t understand me.” Instead she believes that the controversial character of the house has won her more attention.

“When they first saw the house, people would exclaim that it was a “crazy house”! So that’s how it got its name, and now, it’s one of Dalat’s leading tourist attractions,” Nga says.

Nga is more concerned with conveying history and myth through the structural and decorative styling of the house rather than conforming to strict architectural rules. The house for her is interconnected by “a cobweb, which can be conceived as a bridge linking reality and the spiritual world, linking the self and the infinite universe,” she says.

Visitors have been responded to Nga’s creation, one French visitor noted in the guest book: “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.”

The People’s Committee of Lam Dong Province has designated the house as a serious architectural work and its owner, Nga, has had the architectural plans and style of the house copyrighted, becoming the first of its kind to receive such recognition in the province. With the new certificate from the city administration, she now can expand and plans to build another house in 2010.

The nine other buildings selected by China’s People’s Daily include the Forest Spiral – Hunder Swasser Building in Germany, the Ideal Palace in France, the Basket Building, the Public Library Building and the upside down Wonderworks in the US, and the Cubic houses in the Netherlands.
