What architectural styles do you admire?

The architectural style that I admire the most is sustainable houses. I mean it's made of natural materials and energy in a way that can go on without harming the environment. For example, we can re-use existing assets, design for minimum waste, minimum energy uses by using energy from renewable sources such as solar or wind power. So we can protect our planet and decrease the money we have to pay for energy's uses. Second, I always think highly of traditional styles, especially the traditional houses of Viet people. In the long history of the Viet people, we have developed an architecture that is friendly with nature. It consists of one main house, wing houses, a garden, a fish pond, a poultry and cattle breeding ground, a drying yard, fence, gate, etc...Therefore, we make the house and arrange our life activities in a harmony with nature to facilitate a balance to remain a stable and healthy environment.
