Desmond Rea O’Kelly began working on a new headquarters building for the Irish Transport and General Workers Union in 1954. The design evolved through at least four versions before crystallising into the scheme represented by this model. O’Kelly, who was also the building’s structural engineer, proposed a sixty metre (197 feet), seventeen-storey tower, square in plan and transparent in elevation. The original Liberty Hall, headquarters of the Union during the traumatic 1913 Lockout and rebuilt after being badly damaged in Easter Week 1916, was demolished without fanfare in 1958 to make way for its replacement. Construction of the new building began in 1961 and it was completed in early 1965.
Although the mosaic-lined, copper clad, zig-zag roof was just too jazzy for one critic, the building was broadly welcomed by the architectural press. However, it was far from universally popular and continues to divide public opinion. Its original appearance, visible still in the model, was dramatically altered in the wake of a December 1972 car-bomb explosion. A grey putty was applied to the bands of white mosaic which delineated each floor, and in 1973 a reflective film was applied to the glazing, making the building opaque. Ostensibly inserted to counteract solar heat gain, its main benefit was security, a test area of the covered glazing having survived the bomb blast while surrounding windows shattered. The Union itself fell out of love with Liberty Hall in the 2000s and planned to replace it with a taller, broader and deeper tower. The downturn of 2008 ended this project, but the future of Liberty Hall remains uncertain.
