Describe how the environmental sustainability of landscaping materials may affect choices made during the planning and design stage.

Check the origin of materials – do not use Indian imported granite sets or Westmorland lime stone pavement, or recycled; Do not use peat as a soil improver; Local stone from a sustainable source has cheaper transport cost; Use local sourced wood (hazel, willow) from worked/coppiced woods for seats, wattle hurdles, etc.; Use solar powered features, such as water fountains or path lighting. Specify the use of recycled materials such as rock and bricks (features such as stone seats and statues); Local might not mean sustainable. `
