Thomas Patrick Brennan

Irish-born architect and urban planner who shaped the face of post-war Dublin and later left a lasting mark on Rotterdam and Lisbon. A lifelong advocate of affordable housing and public space, Thomas believed that a city belongs to its people - not its investors. He spent over five decades drawing blueprints not just for buildings, but for communities.

He arrived in Rotterdam in 1982 speaking no Dutch and left in 1991 with a city that loved him. He always said good architecture is its own language.

Born in Galway, the youngest of five children. Grew up in a terraced house on Dominick Street — an address he'd reference in interviews for the rest of his life.

Won a scholarship to University College Dublin. First in his family to attend university. Graduated top of his class in 1961.

Joined Dublin Corporation's housing department. Over the next 15 years helped design over 2,000 social housing units across the city.
