In 1917, at the Annual Meeting of the Seamen's Hospital Society, Sir Rosslyn Wemyss and Sir Henry Jackson raised an Appeal for funds to establish a convalescent home for sailors recovering from treatment at the Dreadnought Seamen's Hospital.
In response to this, in 1918 a Mrs Angas, of Stoke Poges, Buckinghamshire, purchased the former vicarage in Cudham for use as such a home. The house had been built in the 1880s for the parish of St Peter and St Paul; the freehold estate included 18 acres of well-wooded grounds.
The Angas Convalescent Home opened on 8th July 1918. It was managed by the Seamen's Hospital Society and had 30 beds.
