No. 45 Merrion Square, the home of the Irish Architectural Archive, is one of the great Georgian houses of Dublin. Built for the speculative developer Gustavus Hume in the mid-1790s and situated directly across Merrion Square from Leinster House, this is the largest terraced house on the Square and is the centrepiece of its East Side. It has a double frontage of red brick and a fine Doric door case. Divided into two separate dwellings in 1829, the house was restored to its original plan by the Office of Public Works in 2004. These works included the refurbishment of the historic fabric and the construction of new state-of-the-art passive archival stores to the rear.
