A late Georgian house, built in conjunction with No. 50 to the east and forming part of a largely unified row on the south side of Mount Street Upper. Despite the loss of some historic fabric, the character of No. 51 has been well-retained. It has the rusticated stone ground floor of houses on this stretch of the street, a fine Doric doorcase with a good fanlight, and ornate metalwork to its full-width balcony and railings. The intact setting enhances it and contributes to the cohesiveness of the streetscape. Laid out in the 1780s and principally developed by a Mr Osburne and David Courtney, the street was built to link the newly constructed Grand Canal to the upper-class residential developments radiating from Leinster House. Built in pairs and rows over a period of thirty years, the fifty-four houses within the street were completed by 1834. Variations, such as differences in parapet heights, are a telling feature of its piecemeal development, with the south side being notably grander than the north, boasting granite rustication across much of the ground floor. The street is terminated at its east end by St. Stephen's Church, transforming what is a typical and relatively modest late Georgian street into an urban set-piece, a key vista of Georgian Dublin.
