AN apartment in the mansion where British prime minister Arthur Balfour was born is now available to buy for offers over £1.85 million.

Whittingehame House in East Lothian was the home of the Conservative premier from 1902 to 1905.

Rooms in the apartment played host to a number of British politicians, including Sir Winston Churchill, and the author Arthur Conan Doyle, who wrote the Sherlock Holmes novels.

During Balfour’s premiership, King Edward VII visited Whittingehame and planted a commemorative oak tree.

Balfour’s tenure as prime minister is noted for his signing of the entente cordiale in 1904 with France.

He also served as foreign secretary later in his career and made the Balfour Declaration – a statement of British support for the establishment of a Jewish homeland in Palestine.

The apartment is the largest (9,022sq ft) in the house, which has been given A-listed status.

Highlights include three opulent state rooms, a secret door in the library and a conservatory that has been converted into a bathroom.

The house sits in 16 acres of grounds, some of which are part of the sale, including a lime walk, a terraced garden within a balustrade, a six-car garage block and a tennis court.

Malcolm Leslie, a partner in Strutt & Parker, which is selling the property, said: “The period elegance and splendour of this, the principal apartment at Whittingehame House, must be one of the finest examples of its kind and is deserving of the ‘best in class’ epithet. It is redolent with history but, equally, offers very comfortable contemporary living. 

“While it is a secluded country property surrounded by fabulous parkland, it is very well placed for the commuter with good road and rail links to Edinburgh.”

Whittingehame’s architect, Sir Robert Smirke, was responsible for a number of neoclassical buildings, including the Royal Mint Court at Tower Hill and the British Museum in Bloomsbury, both London.

Balfour was born in the mansion on July 25, 1848, to Scottish MP James Maitland Balfour and Lady Blanche Gascoyne-Cecil. As well as being born in the house, Balfour also visited during parliamentary recesses.

Against Balfour’s background of support for Jewish people, his nephew and heir Viscount Traprain decided to offer Whittingehame House as 
a safe haven for Jewish children fleeing from anti-Semitism in Europe during the 1940s.

As a result, during the Second World War, the house became Whittingehame Farm School for Jewish refugee children coming 
to Britain through the Kindertransport rescue programme.

The school sheltered 160 children between the ages of seven and 17.

The Balfour family sold the property in 1963 and it became Holt School for Boys, which had originated in Lockerbie. When the school closed in 1980 it was split into apartments.
