 The building is of reinforced concrete construction, and was state of the art in its construction methods at the time – being clad with a curtain wall in opaque dark green glass spandrel panels framed by orange metal uprights.With its original commercial use in mind it featured an advanced elevator system for its day – four Otis "Autotronic" gearless lifts (also used in St. Andrew House on Sauchiehall Street) which were capable of responding to the traffic flow within the building at specific times of the day.The building is electrically heated and was also intended to feature a restaurant on the ground floor which the University later turned into a student refectory.
