Top, Right: Manufactured fiberglass planters were placed on the perimeter edges of the terrace and planted with perennials including hydrangeas, iris, blue catmint, coreopsis and more. This perennial garden area was made of rooftop garden plastic trays. A small metal-framed concrete wall was built between the trays and the fiberglass to hide them. The concrete was finished with a colored stucco to match the existing walls, and then capped with granite. This area was built upon plywood instead of the heavy concrete pavers to lessen the weight. No anchoring was required to keep the planters in place – the size and combined heights do the trick. Additionally, nonbiodegradable packing peanuts were placed underneath the soil to elevate the space using a lighter substance. The irrigation system for the gardens runs on a timer and has a rain sensor. It gets shut off during the winter months to prevent damage from freezing temperatures. The system has worked flawlessly so far, according to TDH. Right: The biggest challenge was getting the materials up to the roof. The townhome is in a five-story building with a spiral staircase, and TDH wanted to minimize the materials brought inside the home and up the stairs. They rented a crane from Coastal Crane Service to move the materials from ground level to work level. The logistics of operating it in the small space proved challenging as well: since the crane blocks the street, arrangements had to be made with the client as well as their neighbors to make sure materials were being moved at times that were convenient for everyone.
