Beautiful Garden Roof for Transformed Post Office in Houston, Texas

Once the hub of the Houston, Texas, United States mail system, the 1930’s-era Barbara Jordan Post Office was a shining example of modern, new formalist architecture.  In 2015, however, the historic post office was closed and fell into a state of abandonment and neglect.  Thankfully, that all changed when efforts surged to transform this 16-acre site into a mixed-use complex topped with a five-acre vegetated and amenity roof.  POST Houston (HTX) highlights how an adaptive reuse project can employ sustainable products and practices to transform a once unused space into a rooftop park with the largest urban farm in Texas. 

This project features American Hydrotech’s MM6125® waterproofing membrane, formulated with a minimum 40% post-consumer recycled content.  Paired with DuPont™ Styrofoam Insulation and American Hydrotech’s Garden Roof® and Ultimate Assembly, the roofing system creates an unbeatable sustainable solution that keeps the owner and designer at ease with an assembly that is covered by a single-source warranty. The Garden Roof and Ultimate Assembly are playing a critical role in protecting this roof, while also providing environmental and economic benefits.
