The double wing expansion house adopts a relatively novel design concept. Through the double wing folding structure, the house presents a complete living space when it is unfolded, and becomes a compact and easy to move device when it is folded. Its design principles stem from the efficient use of space and respect for the environment. It can not only meet people’s pursuit of comfortable living environment, but also meet the requirements of sustainable development of the environment.
