[1] In an edition of The Builder, dated 1873, Matcham was named in the request for tender section as being the accepted party to work alongside Bridgman on the Oldway Mansion project.

[2] The architectural historian Gorel Garlick considers it entirely possible that Matcham was given sole responsibility by Bridgman for the theatre's design because of his educational experiences in London.

[1] Singer spared no cost in terms of Oldway Mansion's construction; he sourced the finest materials from around the world and instructed Bridgman to design the interior in exuberant French style.

[5] The rebuilding work was modelled on the Palace of Versailles,[3] and the eastern elevation of the building was inspired by the Place de la Concorde in Paris.

[3] The ceiling of the staircase is decorated with an ornate painting based on an original design for the Palace of Versailles for Louis XIV by the French painter and architect Charles Le Brun.

[3] The original was purchased by Paris Singer in the late 19th century; the painting was sold to the French government in 1946 and now hangs in the Palace of Versailles.

[10] Following the end of an affair with the dancer Isadora Duncan in 1917, Paris Singer became an American citizen and went to live in the United States.

[5] The Rotunda was converted to house rows of beds for the wounded soldiers being brought back to England from the trenches of France and Belgium.

[18] On 30 April 2012, plans for Oldway Mansion to be converted into a luxury hotel and sheltered retirement flats were approved by Torbay Council.

[23] In January 2016, it was reported that the property developer Akkeron had filed a claim for more than £8 million in damages against Torbay Council, due to a dispute over the leases which it said had caused a delay in starting work on the redevelopment.

In January 2019, it was announced that Torbay Council had begun the process of setting up a charitable trust to allow community management of the building, with the aim of re-opening it.

[21] In March 2019, it was reported that planned open days allowing the public to see inside the mansion had been scrapped, as the building was in an unsafe condition.

[10] In January 2021, Torbay Council applied for permission to demolish the 1930s squash courts adjacent to the Mansion and Rotunda, as they were in a poor condition and putting other parts of the site at risk.

During the spring of 2004, it doubled as Buckingham Palace for the filming of Churchill: The Hollywood Years, starring Christian Slater and Neve Campbell.
