In the 20th century, Irish architecture followed the international trend towards modern, sleek and often radical building styles, particularly after
Partition and the independence of most of
Ireland as the
Irish Free State in the early 1920s. Two major exceptions to this were the
Royal College of Science for Ireland (now
Government Buildings), on Upper
Merrion Street in central Dublin, and
Parliament Buildings at
Stormont in East Belfast, both built in more traditional architectural styles. New building materials and old were utilised in new ways to maximise style, space, light and energy efficiency. 1928 saw the construction of Ireland's first all concrete Art Deco church in
Turner's Cross, Cork. The building was designed by Chicago architect
Barry Byrne, who had learned his craft as apprentice to
Frank Lloyd Wright. It met with a cool reception among those more accustomed to traditional designs.

Art Deco Dublin airport opened, designed by
Desmond FitzGerald and the
Office of Public Works. It was awarded the
RIAI Triennial Gold Medal for the years 1938–1940. In 1953, one of Ireland's most radical buildings,
Bus Éireann's main Dublin terminal building, better known as
Busáras was completed. It was built despite considerable controversy at the time centred on its appearance and high cost(over £1m).
Michael Scott, its designer, is now considered one of the most important architects of the twentieth century in Ireland. Busáras was awarded the RIAI Gold Medal for the years 1953–1955. One of the main proponents of modernist and
Brutalist architecture in Ireland was
Sam Stephenson. Stephenson designed the Civic Offices (1979) and the
Central Bank of Ireland (1980), both of which generated considerable controversy at the time of their construction. In the same period,
Liam McCormick designed the modernist
Met Éireann headquarters in Glasnevin, Dublin (1979). In 1999 McCormick's St Aengus' Church,
Burt, County Donegal was voted Ireland's "Building of the 20th century" in a readers' poll organised by the
Royal Institute of the Architects of Ireland and the
Sunday Tribune, It was also awarded the RIAI Gold Medal for the years 1965–1967.

Donegal by Liam McCormick (1967) In 1987, the government started to plan what is now known as the
IFSC kickstarting a radical redevelopment of the
Dublin Docklands which was to continue through to the 21st century. The complex today houses over 14,000 office workers. In 2010, the
Convention Centre Dublin designed by
Pritzker Prize winning architect
Kevin Roche was completed at
Spencer Dock. From the 2010s and onwards, several new mid to high-rise buildings have been erected in Dublin, such as
Capital Dock,
The Exo Building and
College Square. One of the most iconic structures of modern Irish architecture is the
Spire of Dublin designed by
Ian Ritchie Architects. Completed in January 2003, the structure was nominated in 2004 for the prestigious
Stirling Prize. Other Irish buildings to be nominated for the Stirling Prize include the Ranelagh Multi-Denominational School,
Ranelagh, Dublin (1999), the
Lewis Glucksman Gallery, Cork (2005), and An Gaeláras, Derry (2011) by
O'Donnell & Tuomey, the Millennium Wing,
National Gallery of Ireland by
Benson & Forsyth (2002), the medical school at
University of Limerick by
Grafton Architects (2013), and the
Giant's Causeway Visitors' Centre,
County Antrim by
heneghan peng architects (2013).

Magdalene College, Cambridge (2022). In 2020,
Shelley McNamara and
Yvonne Farrell became only the second Irish winners of the Pritzker Prize (after Kevin Roche). Their
Röntgen Building at
Bocconi University, Milan (completed in 2007) was awarded the
2008 World Building of the Year Award. ==Vernacular architecture==
