This 3,000-sq-ft re-roof provides structural enhancements and creates a shaded outdoor space for building tenants. The historic building actually had an existing roof garden, but it was not up to code. Once it was removed, the team used modular and prefabricated materials to erect a steel frame to span the existing concrete deck and transfer loads to structural columns below. Functional space was created by installing new waterproofing, upgraded electrical, an elevated deck, shade canopy and a long bench for visitors.
Four colors of pickets were attached in a random order to create a varied surface. Recycled glass ballast was used to make the visible roof an aesthetically pleasing area reminiscent of water.
A custom shoring system was placed on the level just below the roof, which allowed for pipe to be placed without disturbing the original structure.
The judges liked this use of space that is typically ignored on other buildings.
