Comfortable surface to walk, sit or lie on. Particularly important if babies or toddlers are involved as sliding, crawling or falling on wood is less damaging than on other hard surfaces. It avoids wet construction, other than post foundations, so it is simple and quicker to erect. Reduces heavy labour, there is no need to dig out foundations, laying slabs, moving large quantities of concrete. Ideal where there are changes in level, a simple way to achieve complex or curvilinear shapes to fit into existing spaces or landscape layout. Includes the facility to add colour to blend in with or enhance the surroundings. Wood is a renewable material, requiring little energy in conversion and production, and efficient use is made of the waste products.
