Nugal Hall sits in the City of Randwick local government area as part of the Eastern Suburbs of Sydney in New South Wales, Australia.

The land grants to McArthur involved four lots aggregating to some 8.4 hectares (20.7 acres) acquired by private tender on both sides of Avoca Street (then known as Frenchman's Road).

[5] Callaghan described the land at the time as resembling Ireland for its picturesque beauty involving waterfalls and rolling farmland from the top of the Randwick ridge line down to Coogee Beach and the Tasman Sea.

Following his return to England, McArthur ultimately became a Member of British Parliament for Leicester in 1874, joining his older brother who was the MP for Lambeth at that time.

Callaghan owned Nugal Hall at the time of his sudden passing in 1865 when he was unexpectedly charged by a colt he had been training at his farm in Braidwood, NSW.

Magnus Jackson Peden and his wife Elizabeth Neathway (née Brown) bought Nugal Hall from Eliza Callaghan for £700 in 1865.

He eventually considered that his most important contributions as a legislator had been his defence of free speech that led to the sedition bill being dropped during World War I and his modification of the (ne temere) Marriage Amendment Act of 1924.

The northern section of Nugal Hall was built between 1885 and 1887 under the supervision of Fred Tidswell, presumably drawing from Tidwell's experience in renovating the Coogee Bay Hotel.

[1] The northern section of Nugal Hall subsumed the original one-storey cottage and servant's quarters into a much larger and grander two-storey residence.

As a result, the main Nugal Hall residence became set back from the straightened Milford Street with a higher degree of privacy.

The German Government leased Nugal Hall from 1901 to 1904 for use by Paul von Buri, the Consul General of Germany for Australia, New Zealand and Fiji.

During this period, Paul von Buri renamed the house ‘Germania’ and hosted a number of prominent social and diplomatic events at the residence.

Various movie stars are said to have used Nugal Hall as accommodation in that period due to their affiliations with Spencer, including Reginald Leslie "Snowy" Baker.

[22] Spencer ultimately settled out of court by allowing his movie business interests to be purchased by The Combine for a substantial sum of money.

[23] Spencer sold Nugal Hall and its extensive contents in 1919 and returned to Canada with significant wealth, buying several ranches in British Columbia and ultimately becoming the largest individual land owner in the Canadian province.

[25][26] Joseph and Roy Ellis were granted consent in December 1921 to implement a subdivision of land to the north of Nugal Hall that was coordinated across several adjacent landowners, known as "Cameron's Estate".

The Coach House at 14 Milford Street was acquired by Nell Pillars in 1969 from the western neighbour, then Thomas Vincent Clune, a hotelier and property developer.

Clune's company, High Cross Estates, later developed the land at 12 Milford Street into the luxury apartment block 'Milford Towers'.

To offset restoration costs, rating and taxation concessions were sought under the Heritage Act, resulting in a 50% discount on annual land taxes that continues today.

[36][37] Downton Abbey is a fictional historical TV drama filmed at Highclere Castle, a spectacular Gothic Revival country home in Hampshire, England.

Nugal Hall was subject to extensive assessments and monitoring by independent consultants in the context of the development of adjacent apartment buildings during 2018–2021.

A media campaign had been conducted by the Campion family to ensure that various concessions were made in the design and construction of the adjacent apartment buildings that were sympathetic to the heritage status of Nugal Hall.

Dilapidation reports of adjacent properties to those developments independently undertaken at the request of Randwick Council indicated that Nugal Hall remains in a structurally sound condition.

[38] During 2021, Nugal Hall was shortlisted as one of two properties to feature as the Prime Minister's residence in the filming of the ABC/Fremantle TV drama production The PM's Daughter.

[39][1] Nugal Hall overlooks Wedding Cake Island and the Coogee land-sea interface, from a ground floor terrace and gardens, ancillary to the east-facing ballroom.

The house has some outstanding interior and exterior decorations and its magnificent upper floor rounded Juliet balcony has views to Coogee Basin and out to sea.

Nugal Hall is of particular importance in Coogee and Randwick where increasing high rise development has deprived the area of much of its architectural history.

At the expiry of the 99 year lease on 9 June 2068, the ownership of the Coach House residence will automatically revert back to the owners of Nugal Hall at that time.

There are three key buildings on that land with an aggregate floor area of 1,612 m2 as set out in the following table: Neighbours to Nugal Hall in immediately adjacent properties have also included John See (NSW Premier, 1901-1904) and George Kiss (Mayor of Randwick, 1877-1879).

As at October 2021, Nugal Hall is of State significance in NSW as an example of an impressive two storey mansion constructed of sandstone in the Gothic Revival style.
