This house was built as a pair with No. 12, possibly to the designs of Edward Lovett Pearce. The house was leased to William Stewart, 3rd Viscount Mountjoy. Recently restored, the interior retains a Portland stone stair with wrought-iron balustrade and timber wainscoting throughout, in addition to some notable Rococo plasterwork. Now in office use, the house forms an important part of what has been described as 'Dublin's Street of Palaces' and greatly contributes to the improving fortunes of this remarkable streetscape.
