Nugal Hall, Historic house in New South Wales, Australia.

Nugal Hall is a two-storey Gothic Revival villa at 16–18 Milford Street, Randwick, completed in 1853 to a design by Colonial Architect Mortimer Lewis. Its south section was built first, with a single-storey cottage and servants' quarters linked to it; these were absorbed into a two-storey northern extension by Oswald H. Lewis in 1885–87. The sandstone was quarried on the site, and the foundation sits directly on rock.

Nugal Hall was built from 1851 to 1853 for Alexander McArthur, an Irish-born gold exporter and clothing importer, on land granted by Governor Fitzroy. The south section was designed by Colonial Architect Mortimer Lewis; the north section was added in 1885–87 by Oswald H. Lewis. It was listed on the New South Wales State Heritage Register on 2 April 1999.

The name Nugal Hall comes from the McArthur family's Irish roots; Alexander McArthur arrived from Derry in 1840. Judge Thomas Callaghan, who bought the neighbouring block, named his own house Avoca after the Vale of Avoca in County Wicklow, and the surrounding streets carry his name: Avoca, Judge, Milford and Ada.

The property is protected under heritage regulations with restrictions on access and modifications to the structure. Check ahead to confirm visiting conditions and any special requirements for viewing the building.

The sandstone for Nugal Hall was quarried on the spot, and much of the surrounding construction was carried out by ticket-of-leave convicts under Judge Thomas Callaghan's supervision; Callaghan likely used the same stone for his nearby house, Avoca.
