Negative pressure tension membrane landscape refers to a type of landscape architecture that utilizes tensioned membranes under negative pressure. These membranes are often made of flexible materials such as ETFE (Ethylene Tetrafluoroethylene) or PTFE (Polytetrafluoroethylene). The negative pressure creates an airtight seal, which helps to maintain the shape and structure of the membrane. This design is commonly used in modern architecture for creating innovative and visually striking structures.
