No. 77 Merrion Square is distinguished from other buildings in the row by its taller five-storey form, probably the result a nineteenth century remodelling. The restrained fa├žade is enlivened by decorative cast-iron balconettes and by transitional features, such as its Doric doorcase with acanthus capitals and coved surrounds. The intact railings and other setting details contribute to the intact appearance of the square. Andrew O'Connor (1874-1941), a noted American-Irish sculptor, died in this house on June 7th 1941. Square was built as part of the original development of the eighteenth-century square by the Fitzwilliam Estate. The square is one of the best-preserved Georgian streetscapes in Ireland. The north, east and south sides are lined with terraced houses of eighteenth and early nineteenth-century date, while the west side is terminated by the garden front of Leinster House . The houses maintain a relatively uniform building height and design, attributed to standards promoted in Fitzwilliam's leases. Individuality was introduced through the design of doorcases, window ironwork and interior decorative schemes. The south side the square was initially set in large plots to twelve leases; plots were leased consecutively from east to west up until the row was completed in 1791.
