Last week, the Olive 8 hotel / condo installed one of downtown Seattle's largest green roofs. The 8,355 square foot green roof is on the fourth floor podium of the Hyatt at Olive 8 and is comprised of two parts. The first part of the installation was on top of the roof's mechanical system. The second installation was on the podium. Judging from the pictures, it's definitely a nice addition for the building and visually more pleasant than looking at the mechanical systems. I would imagine residents will get more enjoyment out of it if it is accessible from the building and they could pull out some chairs and relax on the roof. Read more on the green roof.
