A villa-like house representing an integral component of the domestic built heritage of south County Dublin with the architectural value of the composition suggested by such attributes as the compact plan form centred on a polygonal breakfront showing a modified pillared portico; the diminishing in scale of the openings on each floor producing a graduated visual impression; and the parapeted roofline: meanwhile, aspects of the composition clearly illustrate the continued development or "improvement" of the house for the congregation of the Sisters of Mercy with those works including an adjoining chapel erected ("1916") to designs by William Henry Byrne and Son (formed 1902) of Suffolk Street, Dublin (DIA). Having been well maintained, the elementary form and massing survive intact together with quantities of the original fabric, both to the exterior and to the interior including 'a most attractive oval entrance hall with an inlaid floor' (Pearson 1998, 148): however, the introduction of replacement fittings to most of the openings has not had a beneficial impact on the character or integrity of a house having historic connections with Lieutenant-Colonel Henry C. Cash (1790-1843) of the Queen's Royal Regiment (Lewis 1837 II, 116; The United Service Magazine 1843 I, 480); and Sir John Barrington (1824-87), Lord Mayor of Dublin (fl. 1865; 1879; Gaskin 1866, 472).
