No. 57 Merrion Square forms part of the eighteenth-century square developed by the Fitzwilliam Estate. The restrained façade of this building is enlivened by its Ionic doorcase, complete with decorative fanlight and sidelights, and by the good metalwork to its balconettes and railings, all of which provide visual and craft interest. The building and its intact setting details contribute significantly to the intact appearance of this important architectural set-piece. 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 of Merrion Square was initially set in large plots of twelve leases; plots were leased consecutively from east to west until the row was complete in 1791.
