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.
