The former home of a doctor who helped Winston Churchill overcome a speech impediment and was later physician to King Edward VII is now on the market for £4.5m.

Grade II listed Rignalls in Great Missenden, was built for Sir Felix Semon, a German throat and speech specialist who went on to develop the first surgical treatments for throat cancer.

In 1897, the same year he was knighted, he helped a 23-year-old Churchill overcome his lisp while in the military and in 1901 was appointed Physician-Extraordinary to Edward VII.

Semon had Rignalls built in 1909 when he retired from professional life, living there until his death in 1921.

During the Second World War the house was owned by a member of the free French government and leader Charles de Gaulle is reputed to have visited on numerous occasions. 

The property was designed by Arts and Crafts architect Charles Holden, best known for his London Underground stations of the 1920s and 30s.

Its sellers explained that the current owners have undertaken a thorough programme of renovation, employing the services of London-based architect Keyvan Lankarani, a specialist in bespoke conservation works, and Patrick Baty, a specialist in historical decorating.

The house, which is around a mile from Great Missenden village, comes with 10.3 acres of land, including an orchard, mature woodland, stables and paddock.

The gardens were created by renowned horticulturalist Gertrude Jekyll, who designed and advised on more than 400 gardens in the UK, Europe and America.

They have been restored "faithful to Jekyll’s original design" with the help of horticultural architect and historian Todd Longstaff-Gowan and include a York stone terrace that flanks the south of the property, with brick steps leading down to various levels of lawn surrounded by shrubberies and laurel hedges.

Alex Newall, managing director at real estate advisory firm Hanover Private said: “The gardens have Jekyll’s signature, with features typical of her style.

"Enjoying an elevated position with a mature wooded backdrop, the outside space has the most wonderful views of the Hampden Valley, while the lawned areas enjoy a carpet of daffodils and blue bells in the spring months.”

Rignalls is listed for sale with Strutt and Parker and Hanover Private for a guide price of £4,000,000.
