Thomas Francis McNamara, RIAI, RIBA, (1867–1947) was an Irish Roman Catholic ecclesiastical architect active throughout the late-nineteenth- to the mid-twentieth-century Ireland who designed many hospitals and Roman Catholic churches.
[1] At the office of William Hague, an architect who designed many Roman Catholic churches generally in the French Gothic style, McNamara rose from being a pupil to managing assistant.
Hague died 1899, the year Omagh’s Sacred Heart was dedicated and consequently it was "a culmination of [Hague's] amazing catalogue of completed ecclesiastical designs and his continuous championship of the Gothic Revival style," according to Richard Oram in Expressions of Faith-Ulster’s Church Heritage.
His office was located at Dawson Street, Dublin until 1911 and at number 50,[4] and number 5 from 1927 until his death; working at 192 Great Brunswick Street, Dublin from 1911 to 1927.
[1] In 1912, he was appointed architect to the Dublin Joint Hospital Board.
