Plan view of elevated green roof

Quick answer：

An elevated green roof, also known as a raised green roof, is a type of green roof system that is built above the level of the roof deck. The plan view of such a roof would show the layout of the vegetation, soil depth, drainage systems, and other components of the green roof. This type of green roof is designed to provide additional space for growing plants while also serving as an insulating layer for the building, reducing energy consumption, and improving the urban environment.
