Qingdao Laoshan Grand Mansion is located at the foot of Laoshan Mountain, adjacent to the egret habitat of Zhangcun River. Based on the design inspiration of "the journey of the egrets returning to the nest", the project strives to achieve the integration of natural aesthetics and human care and create an urban residence by the mountain and sea that coexists in harmony with the environment. It seamlessly connects the underground multipurpose space with the landscape above ground, creating a new living experience.
