From Wikipedia:

Churchill and his wife Clementine bought the property in 1922 and retained it until his death in 1965. He employed architect Philip Tilden to modernize and extend the somewhat featureless brick house[1] that stood on the property. Tilden transformed the house between 1922 and 1924, simplifying and modernising it, as well as allowing more light into the house through large casement windows, working in the gently vernacular tradition that is familiar in the early houses of Edwin Lutyens, a style stripped of literal Tudorbethan historicizing details but retaining multiple gables with stepped gable-ends, and windows in strips set in expanses of warm pink brick hung with climbers.

As at many such early twentieth-century remakings of old houses, the immediate grounds, which fall away behind the house, were shaped into overlapping rectilinear terraces and garden plats, in lawn and mixed herbaceous gardens in the Lutyens-Jekyll manner, linked by steps descending to lakes that Churchill created by a series of small dams, the water garden where he fed his fish, Lady Churchill’s Rose garden and the Golden Rose Walk, a Golden Wedding anniversary gift from their children. The garden areas provided inspiration for Churchill’s paintings, many of which are on display in the house’s garden studio.

During the Second World War, the house was mostly unused. Its relatively exposed position so near to German-occupied France meant it was potentially vulnerable to a German airstrike or commando-style raid. The Churchills instead spent their weekends at Ditchley, until security improvements were completed at the prime minister’s official country residence Chequers.[2]

The house has been preserved as it would have looked when Churchill owned it. Rooms are carefully decorated with memorabilia and gifts, the original furniture and books, as well as honours and medals that Churchill received.

The property is currently under the administration of the National Trust. Chartwell was bought by a group of Churchill’s friends in 1947, with the Churchills paying a nominal rent, but was not open to the public until it was presented to the nation in 1966, one year after Churchill’s death.

“A day away from Chartwell is a day wasted.” - Winston S. Churchill

Winston Churchill was born at the Blenheim Country Estate 1874 and was the son of Lord Randolph Churchill and the American actress Jennie Jerrome. Churchill’s public life evolved over a period of 64 years having first entered the British Parliament just shy of his 26th birthday. During his lifetime he served the people of England as Home Secretary, First Lord of the Admilitary, Chancellor of the Exchequer, and Prime Minister on more than one occasion.

Churchill possessed amazing courage, unshakable principles, deep compassion, and he was a fiece defender of freedom. He was a dynamic character who enjoyed the pleasures of life at Chartwell his country home from 1922 - 1965. From Chartwell he wrote his memoirs, enjoyed his cigars, painted, became a skillfull mason, entertained his guest and raised his children along with his wife Clementine (Hozier) Churchill.
