A mid-eighteenth-century townhouse, converted to offices in 1869 by contractor, John Nolan, and now in use as offices for the National Library. Although the interior has been gutted and despite the loss of historic external fabric the building has retained its historic composition and contributes to the historic character of Kildare Street. Formerly called Coote Lane, the street was widened and renamed after 1745, when work on Leinster House began. Many houses in Kildare Street were built in the mid-1750s by John and George Ensor, although No. 5 is slightly later in date.
