A farmhouse 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 Classically-detailed doorcase not only demonstrating good quality workmanship, but also showing a simplified "peacock tail" fanlight; and the diminishing in scale of the openings on each floor producing a graduated visual impression with the principal "apartments" defined by elegant bipartite glazing patterns. A prolonged period of unoccupancy notwithstanding, the elementary form and massing survive intact together with substantial quantities of the original fabric, both to the exterior and to the interior, thus upholding the character or integrity of a farmhouse having historic connections with the Grehan family including Thomas Grehan (1830-1918), 'Farmer [late of] Mullinastill Shankill County Dublin' (Calendars of Wills and Administrations 1918, n.p.).
