Sam Stephenson has made a huge impact on Dublin. Many of his buildings generated considerable controversy when they were built. His most famous buildings are all in Dublin, and exemplify the style of Brutalist architecture.

The One Building, formerly The McInerney Building, pushed the boundaries of Irish Architecture. His ambitious and unique brutalist style of architecture encouraged a modern approach to Irish designers at the time.

Sam Stephenson buildings remain today as symbols of progression in architecture.
