<p>Intensive green roofs are commonly used for amenity space on condo developments or sometimes as urban farms. They are sometimes referred to as Roof Gardens and encompass diverse uses, design priorities and technical specifications. In the most extreme examples, many urban parkettes including large shade trees may be included in this class, if they have parking garages beneath. As such the discussion on this page is limited to extensive green roofs. </p>
