Dublin, the capital city of the Republic of Ireland, has fewer high-rise buildings than most of its European counterparts.  Even so, plans are under way to demolish the city’s first and currently tallest sky-scraper, Liberty Hall.  Ireland’s largest trade union SIPTU owns the site and is already working with Gilroy McMahon Architects on the replacement.

There has been considerable opposition to the destruction of buildings in Dublin from earlier times, Georgian in particular.  But architecture from the last 100 years is afforded less protection and support.

Going back a century or so, the Northumberland Hotel previously stood on this site by the River Liffey between the Customs House and the city centre.  The Irish Citizen Army was housed here when it was defending workers against the authorities during the 1913 Lockout and it played a central role in the 1916 Rising.  During this time, the hotel was the first target of a British gunship know as the Helga, while it was on its way upriver to shell the GPO.  Following this, the building was patched up and became the headquarters of the Irish Transport and General Workers’ Union.

By the end of the 1950s the building had fallen into disrepair, so the union decided to replace it with a new building and the architect Desmond Rea O’Kelly was commissioned.  Construction began in the early 1960s and “Ireland’s first sky-scraper” was completed in 1965 to much awe and excitement.

In its original form, the building presented most of its 16 storeys simply, as a slender stack of alternating layers of light and dark capped by a distinctive zig-zag copper roof.  The concrete floor-plates were tiled with white mosaic which contrasted with shaded office interiors visible through transparent glass.  This impression inverted at night when the illuminated offices on each storey appeared to float above the other as the unlit mosaic disappeared against the dark sky.  By day, the original glazing allowed you to see sky through the corners of the building.  Creating a lightness of effect that architectural historian Ellen Rowley compares to “a skeleton that’s draped in a glass garment”.

A large explosion from a bomb left outside Liberty Hall in the winter of 1972 blew out most of the glass.  When this was being replaced however, a reflective silver film was added to all the windows, taking away the delicate translucent effect.  This plastic has since discoloured unevenly and has partially peeled off in many places.  Further to this, the sparkling white mosaics on the floor-plates were later daubed with a putty that has since gone a dirty grey.

Since these changes to the facade, Liberty Hall has fallen from grace somewhat in the eyes of the public, and in 2006 the Union advertised for expressions of interest from architects to work with them on a replacement building.  Liberty Hall’s architect Desmond Rea O’Kelly, now in his 80s, spoke about the future of the building during a recent public talk, saying “You needn’t worry.  I’m not going to shed any tears.  But would they kindly leave it alone until I’m gone!”
