Prior to this John Macarthur received a grant on the southern side of the Nepean River of 2,023 hectares (5,000 acres) and this became known as Camden Park Estate.

Governor Macquarie granted two of Macarthur's employees, John Condron and William Parrott (both convicts who subsequently obtained freedom) each 40 hectares (100 acres) in 1810 and 1812 respectively.

Structures such as Camelot at (nearby) Kirkham, Camden Park House, built for the Macarthur family, and Fernhill at Mulgoa to the north are examples.

The house at Studley Park is a good example of this, situated on a rise and equipped with a tower (Campanile) which enhances its visibility and makes it a prominent landmark in the area.

The total remaining area today is 142.412 hectares (351.91 acres), including golf course, land for flood mitigation works, house lot etc.

Two areas of woodland abut the Army era buildings east of the main house, and in the golf course's north-east corner towards Camden Valley Way.

It could have been set further east, on the highest point, but to do so would have made it less visible from Camden Valley Way, formerly the Hume Highway, and from the neighbouring mansions Camelot and Kirkam, on the Cobbity Hills opposite.

The entry to the carriage drive was marked by a handsome gateway with white painted, decorated timber posts capped with finials and rails from which wire mesh was hung.

A. Gregory in 1933, was an elaborate pergola and lattice construction on a low earth platform in the southern sector of the garden, adjacent to the kitchen block and former dining room.

The lattice screen walls were at least 3 metres (9.8 ft) high and a doorway and a few steps gave access between the interior "garden room" and the lawn outside.

An ornate Italianate fountain was located at the centre of a circular mound, which appears to been sited directly over, or close to, the original well (from which it no doubt drew its water).

[1] Few details exist of the garden to the north of the House, other than the post and lattice framework that defined what appears to have been a shrubbery (the plants are too substantial to be vegetables).

A wide flight of steps leads up the mound or platform of the house into this area, which is defined on its outer boundary by a white post and rail fence.

The land beyond the House grounds to the west and south was mostly covered with grass for grazing, with few trees left standing When that ceased, it was rough cut, being used as fairways for the golf course.

A white painted timber post and rail fence also ran along the outer edge of the carriageway, to ensure that vehicles did not stray over the fairly steep battered slope of the House's mound or platform.

[1] A tennis court existed in the front yard/paddock to the south-west of the house from early on, although it is not clear whether this was built by the original owner, Mr. Payne, his successor Mr Buckle, or by Dr Oliver when the property was re-developed as a school after 1902.

On page 37 of the CP, it states that a Mr K. C. Whyte acquired a grazing licence over 57 hectares (140 acres) of the site and planned to reconstruct the golf course (which confirms that it previously existed, although probably in an amateurish form).

However, while the Club also made some 'dramatic alterations"[19] to the landforms when redesigning the golf course, the continued existence of the extensive fairways has preserved the important vistas between the House and the main roads, in a broad arc from the south-west to the north-west.

The curving form reflects 18th century landscape design, retained for use in providing different visual sequences to, and a final impressive display of, the grand House in the process of arrival.

[1] The carriage loop has a moderate to high degree of historical and aesthetic significance, having essentially the same configuration as that of the original, although without the accompanying post and rail fence and associated plantings of Pine Trees.

[1] The tennis courts (or at least their sites) have a moderate degree of historical and social significance, demonstrating a form of recreation favoured by landowners and schools for gentlefolk for the first three to four decades of the 20th century.

Its existence as a rich textural backdrop and setting to the House gives it some aesthetic value, as does the screening it provides for the otherwise visually intrusive Army barracks.

[1][14] A fine example of a Boom style high Victorian mansion, set in a prominent location, with its outbuildings representing an important period in a series of large nineteenth-century houses in this region.

External walls of heavily moulded cement render, encrusted with a profusion of debased architectural detail of vaguely Italianate character.

Internally exuberant style of exterior is maintained, grand staircase with open first floor gallery, stained glass, fine woodwork.

[1] Studley Park House is an excellent example of Victorian Italianate architecture, enhanced by its prominent location and open landscape setting.

[1] Subsequent phases of use of Studley Park provide evidence of important themes in Sydney's history, including school education, defense and recreation.

[1] The period of ownership of Studley Park House by Arthur Gregory in the 1930s is represented by its remaining "Hollywood" style internal finishes and is supported by high quality contemporary photographs.

[1] While compromised by modern additions, the former Stables building (current Golf Clubhouse) retains an historic and visual relationship with Studley park House and has the potential to be reconstructed in its original form.

The archaeological resource of the site of Studley Park has the potential to contribute to an understanding of some aspects of the construction and maintenance of a substantial late-nineteenth century 'country estate'[20][1] The site has natural heritage value in retaining two areas of regenerating remnant (endangered ecological community) Cumberland Plain Woodland including a population of the nationally endanaged shrub species, Pimelea spicata.
