The brutalist extension to Belfast’s Ulster Museum has become such a familiar sight in south Belfast that it is difficult to imagine any alternative. Loved by architects and hated by much of the public, the addition has been described as ‘Belfast’s Busáras’. It was built as a result of a design competition in 1964, won by the previously unknown architect Francis Pym who synthesised the Neoclassical lines of the existing building with austere cubist forms. His design could not have been further from that of the joint second place winner: Archigram.
