Materials are as important to the scheme as the design and planting. There are a wide selection of materials to choose from, depending on locality, architecture of the house and the surroundings. Taking this into account and always searching for new materials, here are some of the traditional and modern materials that Roberto Silva likes to use in his gardens:
York stone, Indian sandstone, limestone, wood, railway sleepers, gravel, slate, stainless steel, cobbles, cor-ten steel, concrete, wood, glass, granite sets, railway sleepers, and so on. |
