No. 78 Merrion Square retains its historic character, featuring an elegant, wide tripartite Ionic doorcase with decorative (albeit replacement) sidelights. The ornate balconettes and the more sober window-guards add further visual interest to the to the otherwise restrained fa├žade. The intact setting features contributes significantly to the intact appearance of the square. Developed as part of the Fitzwilliam Estate, Merrion Square is one of the best-preserved Georgian streetscapes in Ireland. The north, east and south sides of the square 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 terraced 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 of Merrion Square was initially set in large plots to twelve lessees; plots were leased consecutively from east to west up to 1791.
