The story
Edward Mahoney arrived in Auckland in 1856 after emigrating from Cork in Ireland with his wife and three children. Edward was initially a merchant in Auckland selling building materials before becoming an architect. In 1876 Edward Mahoney formed an architectural practice with his son Thomas. In the 1880s, Edward's son Robert joined the practice. Edward retired from the practice in 1885 and Robert died in 1895. Thomas named the practice E. Mahoney & Son after Robert's death. The practice continued after Thomas' death in 1923 until closing in 1926.
