Despite having been in practice since the 1850s, business was slow until he was discovered by the
Rothschild family. This international dynasty of bankers would provide Devey with numerous commissions and ensure a steady stream of work. Devey first appears in Rothschild account books as the architect for a new school at
Hulcott, and the rebuilding of the parsonage there. In 1863 he came to attention of Sir Anthony de Rothschild when he designed
Buckland School for the vicar Edward Bonus on a site donated by the Rothschilds. He succeeded
Joseph Paxton's son-in-law
George H. Stokes as
Baron Mayer de Rothschild's architect for the estate village at
Mentmore, designing the stables and riding school there between 1869 and 1870. After the Baron's death in 1877, Devey continued in the employ of his daughter
Hannah de Rothschild building cottages at
Wingrave and Mentmore. His most notable works on the Mentmore Estate are: Rosebery Arms at
Cheddington, the School House at Cheddington, and the Thatched Lodge, which stands at the end of a long avenue approach to
Mentmore Towers. designed to appear as one house, typical of those designed by George Devey for
Hannah de Rothschild. The tall chimneys were to be a feature employed by
Lutyens thirty years later Photographed circa 1968. Devey was largely responsible for
Ascott House, a neo-Tudor extravaganza developed from a small half-timbered farmhouse. He began work there in 1874 for
Leopold de Rothschild. This house, conceived as a small hunting box, expanded, the intention was to make the house seem as though it had grown and developed over centuries. Devey designed numerous half-timbered extensions. He was still working on the house at his death in 1886, when his partner James Williams took over the project. Ascott House is probably Devey's greatest monument, although further half-timbered extensions continued to be added to this house as late as the 1930s. Devey was also responsible for the large cottages on the Green, near the entrance of Ascott House, (now the Ascott Estate Office); these are very similar to those he designed at St. Albans's Court,
Kent, in the late 1880s. A further Rothschild house by Devey was
Aston Clinton, where he worked with George Stokes. The Italianate house with its huge porte-cochere is now demolished, a casualty of the
huge country house demolitions of the 1950s. However, the Lodge and stables by Devey still stand, as does his West Lodge at Aston Clinton. Although the records were destroyed in
World War II, he is also believed to have worked on the "improvements" at
Tring Park between 1874 and 1878, which involved turning a house designed by
Sir Christopher Wren into a
dix-huitieme French
chateau complete with
mansard roof. Devey later built a house very similar to the transformed
Tring in Lennox Gardens, London, for a Mrs. Hunloke. Devey was capable of working on more than one project at a time. In 1876,
Alice de Rothschild commissioned him to build her a house at
Eythrope in the
Vale of Aylesbury. After the plans were drawn up, his patroness decided water at night was bad for her health Since the house was in a bend of the River Thame, rather than abandon the site, she decided Devey must design a house without bedrooms, and she would decamp every evening to her brother's home,
Waddesdon Manor. The result was the Eythrope Water
Pavilion, one of the smaller of the Rothschild houses of Buckinghamshire, its design is an unostentatious complement to the great faux-chateau four miles away of
Waddesdon Manor. Today (with a bedroom wing added in the 1920s) it is the only Rothschild mansion still in private hands in the
Vale of Aylesbury. The Rothschilds also commissioned him to undertake work at their newly acquired property
The King's Head in Aylesbury itself. His work mainly consisted of creating what was considered a typical Tudor experience in the 14th century coaching inn, but actually followed Victorian conventions of the time. Much of his work here was not corrected until after the property was given to the
National Trust, when a more authentic Tudor appearance was restored, though elements of his design can still be seen. He designed in Hampshire for
George Carnegie, 9th Earl of Northesk Devey had an interest in garden design and played an important role in not only the houses he designed, but also in garden buildings and
follies. At Ascott this included the thatched half-timbered summer house, or skating hut overlooking the circular
lily pool. He has also been credited with the design of the neo-Grecian temple terminating the avenue of mirror
herbaceous borders, but the style is to very different that he normally employed. ==Other patrons==
