Green roofs are the great green hope of many environmentalists, politicians, and architects interested in more efficient and environmentally aware buildings. From the design standpoint, however, there are fewer consensuses. While some see the roof garden as a visual statement using plants, geometric lines, and sculptural elements, others believe concerns for sustainability should outweigh visual appeal. A green roof that combines aesthetics and mechanics has become the goal of many a landscape architect.

In Green Roof Gardens, author Christian Werthmann explains the history, methodology, and design process of green roof garden construction, providing a rich source of inspiration and technical knowledge in the process for anybody interested in this simple solution to many of the environmental challenges we face today.

This book is perfect for readers who already know that green roofs are good for our planet, but are looking for technical information on how to build one. Product and plant guidelines and the construction process are marvelously detailed. It's also generous with photos and diagrams. This particular green roof demonstrates that they can be more than just sedum in planters on a flat roof--green roofs can be a building amenity and enhance the view shed for nearby buildings as well. The book is very well written. It should be noted that the author is a German landscape architect and Germany leads the world in green roof design. An excellent resource for developers, real estate executives, building owners, and designers.
