Around 1824 Notman joined his older cousin, William Notman to train as an architect in the office of William Henry Playfair in Edinburgh prior to emigrating to the United States in 1831. He eventually settled in Philadelphia, where one of his first commissions was Laurel Hill Cemetery in 1835. He later opened and operated a successful firm until his death in 1865. Notman was also a founding member of the American Institute of Architects and was committed to establishing professionalism in the practice of architecture in the United States.
Notman is credited with introducing the Italianate style to America. "Riverside", his 1837-39 house in Burlington, New Jersey for Bishop G.W. Doane, was tremendously influential, and his 1845 Athenaeum of Philadelphia was the first Italianate building in his adopted city. Notman designed a number of suburban villas and country houses, including "Ogontz" (1863) for financier Jay Cooke.
Many of his designs for churches were dictated by the ideas of the Cambridge Camden Society who suggested that Anglican churches of the Low church variety should be built in the Romanesque style, while those of the High church variety be built in the Gothic style. He was also briefly employed by the Roman Catholic Diocese of Philadelphia during construction of the Cathedral Basilica of Saints Peter and Paul until an argument over the terms of his contract resulted in his dismissal.
Following Notman's death, the firm continued for a couple years under his protege George Hewitt. He is buried in Laurel Hill Cemetery. John's brother, Peter Notman, lived on Joralemon Street in Brooklyn Heights and sold fire insurance. His children, John's nieces and nephews, are memorialized on a bas-relief in the crypt of St George's Episcopal Church on Stuyvesant Square in New York City.
