Fencing and barriers in landscaping require careful consideration of specifications to ensure functionality, durability, and aesthetic appeal. Key specifications include material selection, such as wood, metal, or composite materials, chosen for their suitability to the environment and desired aesthetic. Height and design play crucial roles in providing privacy, security, and visual integration with the landscape. Additionally, factors like permeability for drainage, maintenance requirements, and compliance with local regulations must be considered. By addressing these specifications thoughtfully, fencing and barriers can enhance outdoor spaces while meeting practical needs and sustainability goals.
