Works attributed to Thomas Newenham Deane, and his architectural practice, include the National Library of Ireland, a wing of the National Gallery of Ireland, St Mary's Cathedral, Tuam, the Kildare Street Club, and a number of buildings in the Trinity College Dublin campus.
This aspiration was nonetheless denied by his father, and following primary school in England, Deane, in 1846, travelled back to Ireland to attend Trinity College Dublin (TCD).
[3] As years went on, Deane became a more integrated part of the architecture firm, a practice he officially joined in 1850 and later was to take over after his father passed away in 1871.
Towards the end of his life, he managed to become a regularly figured artist in the Royal Hibernian Academy in Dublin.
[2] He was known as a conservation architect, involved in the restoration (including the incorporation of the original twelfth-century Romanesque chancel) of St Mary's Cathedral, Tuam.
His work on the conservation of St Canice's Cathedral, Kilkenny, was less successful and brought him into conflict with the dean and chapter, and in particular with the treasurer James Graves.
In contemporary circles, Deane's partner Woodward was seen as the creative influence behind the business, and their practice suffered after his early death.
