Johnstone Hall

Johnstone Hall – dormitory at Clemson University.

The Johnstone Hall complex became a model for college dormitories, implementing a new raise-slab construction method, a practice which was featured in many architectural magazines at that time. This method – the Youtz-Slick "lift-slab" method – lifted reinforced concrete slabs onto columns with hydraulic jacks. These slabs weighed 224 tons and were nine inches thick, 122 feet long and 43 feet wide. Today, only one of the original Johnstone buildings is still standing on the campus.
