The Vietnam Book of Records, VietKings, has recognised an ecological house in the shape of a conical hat with a roof made from 2.4 million pieces of coconut.

The house, 12.03m high with a diameter of 27.1m, is located in Vinahouse Space in central Quang Nam Province's Dien Ban District, about 7km from the ancient town of Hoi An.

It took about 250 workers 55 days to build the house.-VNA
