Maurice Craig, writing in 1973, noted Sally Park among the eighteenth-century houses of the county, and the building is thought to predate 1740, placing its construction in the early Georgian period, before the great wave of country-house building that would reshape the Irish landscape across the latter half of that century. The house was associated with Handcock, the historian of Tallaght, whose connection to the locality gave Sally Park a particular significance beyond its modest architectural footprint. A four-bay facade across three storeys is a fairly typical expression of the period's domestic ambitions, plain and proportioned rather than showy, the kind of house built by a family of some local standing rather than great landed wealth.

The house lies in Tymon South, a townland now largely absorbed into the suburban spread of south-west Dublin, which makes locating any earlier fabric of the landscape a matter of patience and careful looking. The building itself is the thing to seek out rather than any surrounding demesne, which has not survived in any obvious form. Visitors with an interest in the early layers of Dublin's hinterland may find it worth pairing with a broader look at the Tallaght area, where traces of an older settlement pattern occasionally surface beneath the modern development.
