Easneye Mansion had been the family home of the Buxtons since being built by Thomas Fowell Buxton (Jnr) in 1868. Buxton's father, Sir
Thomas Fowell Buxton (Snr), had made his fortune (along with Messrs Truman and Hanbury) by brewing and popularising porter (beer), which was considered to be a cheaper, more nutritious and healthier alternative to
gin. Sir Thomas was a member of the reformist
Clapham Sect and it was to him that the ailing
William Wilberforce entrusted the oversight of the
Emancipation of Slaves Bill, which Buxton eventually got through Parliament in 1832. This earned him not only a Baronetcy but also the title of "The Liberator". His sister in law was the penal reformer
Elizabeth Fry, and Buxton could be seen beside Fry on the back of the previous edition of the English £5 note from 2001 to 2016. Buxton's brewery was successful and eventually enabled his son to buy the estate at Easneye (Anglo-Saxon for water-island) and build the mansion under the direction of the architect
Alfred Waterhouse. It is a
Grade II* listed building. As the Buxtons moved into Easneye, Hannah, the wife of Sir Thomas Fowell Buxton Snr, wrote a letter expressing her desire for a dedication service to be held, which contained the prophetic wish: "(May) this house ever be inhabited by faithful servants of God in and through Jesus Christ .. and may this place be a fountain of blessing in the church and in the world".
Arthur Buxton (1882–1958) lived here in his youth. During the lifetime of the owner all available family and employees would gather in the Main Hall for morning prayers to be offered on behalf of the estate, the church and the world; and a grandson of Sir Thomas Fowell Buxton Snr,
Barclay Fowell Buxton, went as a missionary to Japan, while some of the household servants also went overseas in Christian service. Barclay Fowell Buxton's son,
Godfrey Buxton, founded a precursor institution of All Nations Missionary College. In May 2025, the trustees announced their intention to move from the Easneye campus and the house and grounds have been put up for sale. ==Principals of the college==
