No. 42 Merrion Square forms part of the original development of the eighteenth-century square. It was built on a plot leased to Nicholas Le Favre, lottery office keeper, in the late eighteenth century. It retains an Adamesque doorcase complete with decorative sidelights and fanlight, that provides a decorative focus to the otherwise restrained fa├žade. It displays good fenestration with typical panages to the openings. Together with its intact setting details, this building contributes to the intact appearance of the square. The survival of an early decorative coal-hole cover is increasingly rare. Developed as part of the Fitzwilliam Estate, the 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 nineteenth-century date, while the west side is terminated by the garden front of Leinster House. The houses of the east side are the most uniform of the terraces on the Square, maintaining similar building heights and fenestration patterns. Individuality was introduced through the use of elaborate doorcases, window ironwork and interior decorative schemes. The east side of the square was originally set out in five large plots and the houses built here were generally narrower than those on the north side and erected in a piecemeal fashion.
