Built c1756 for the Rev. Cutts Harman, Dean of Waterford. The porte-cochere is unique in Dublin townhouses of the period; its design tallies with a drawing by the C18 architect Joseph Jarratt. The original brick façade was remodelled in the Italianate manner in the C19 by Michael Bernard Mullins. Further additions, including the mansard roof, were added 1901-2 under the direction of William Henry Byrne and Sons. Now the St Stephen's Green Club. The interiors have decorative plasterwork attributed to Paolo Lafranchini, given its similarity to comparable work executed by him at Castletown, Co. Kildare in 1759.
