" “I have had many years’ experience with green roof installations that have not been consistent with the overall quality of our properties. With Columbia Green, I have finally found a green roof partner that has exceeded my expectations in their product and their professional approach in this emerging market. We look forward to working with Columbia Green into the future and will gladly continue to recommend Columbia Green to other developers.”

"“The plantings thrived within the first season, the project was a major success, and it is considered by many as a building of its time as it relates to the outdoor amenity it provides for its tenants.  Over 3,000 helicopter lifts were required for delivery of the structural and landscaping components. The final product speaks for itself and with the help of the Columbia Green team we were able to transform the rooftop at the Old Post Office into a 3.5-acre park, 10 stories up in downtown Chicago"
