Today, the trees are a landmark and contribute to the character of the rural landscape north-west of Picton. The listing includes all trees and buildings on the land from road to hill top. A colonial Georgian brick house with front verandah, the main block being flanked by slightly later ones which at the rear form a U-shaped verandah court with the centre block. The whole is raised on a terrace at the front which is unusual. The main block is double pile plan and the elevation is five bays wide under a hip roof of shingles covered with corrugated galvanised iron. Internal detailing is intact. Originally a Colonial Georgian, one storey house flanked by later gabled pavilions forming a U-shaped verandahed courtyard with the whole raised on a high terrace at the front. Face brick on rubble foundation for main block. Two brick outbuildings are associated with house; one containing a kitchen and servants' quarters, the other a smokehouse. Twice destroyed by fire in last decade and main building now derelict. The ruins of the main "Abbotsford" farmhouse are significant for their associations with the settlement of the area and the links with the Harper and Antill families. The architectural value and intactness of the house as an early homestead has been lost. The ruins, together with the other components of the property, provide an opportunity to interpret an early pastoral property through archaeological investigation. The ruins are also an evocative part of the Abbotsford group which is a landmark in the rural surrounds of Picton. The cottage was used as servants' quarters and the brick outhouse as a smokehouse. These domestic buildings are thought to date to the mid 19th century. Together with the main residence these two buildings and the gaol (now demolished) were positioned around a central court with a deliberate axial relationship to the hill, the driveway and selected trees. A large brick tank about in diameter. It is internally rendered, capped with a brick dome and still holds water. As well as the water storage tank there are other sites considered to be of archaeological interest. They are the site of the "Old Gaol" or Convict Barracks, a line of stones adjacent to the existing timber barns and the remains of a floor surface (LEP). The ruins, together with the other components of the property, provide an opportunity to interpret an early pastoral property through archaeological investigation. The ruins are also an evocative part of the "Abbotsford" group which is a landmark in the rural surrounds of Picton.
