This detached garage showcases the possibilities you can have with a green roof.  It is a traditional extensive green roof designed with 3 soil planting depths, supporting sedum, native grasses and perennials.   It is also equipped with a drip irrigation system for a garden that produces fresh vegetables and herbs throughout the year.  Only 365 square feet, this roof is visible from the alley and surrounding homes and has opened a lot of eyes in this NW community.
