In biophilic design, which connects people with nature in built environments, the durability of natural materials is crucial. This comparison examines how various natural materials stand the test of time, helping you make informed choices for long-lasting biophilic installations.
What Makes Natural Materials Essential in Biophilic Design?
Natural materials form the backbone of biophilic design, creating authentic connections to nature within built spaces. These materials bring textures, patterns, and colors from the natural world into our indoor and outdoor environments.
When selecting natural materials for biophilic applications, durability becomes a critical factor:
- It maintains the intended design aesthetic over time
- It minimizes replacement needs and associated costs
- It reduces resource consumption and waste
- It aligns with sustainability principles
