country house, administrative and historic county of Buckinghamshire, England, situated 30 miles (50 km) northwest of London, the official country residence of the prime ministers (prime minister) of Great Britain. The estate is about 1,500 acres (600 hectares) in extent. Chequers owes much of its present character to the remodeling, in 1565, of its predecessor. In the 19th century the exterior was plastered and the interior redecorated in neo-Gothic style. In 1917 Viscount Lee of Fareham made provision, with parliamentary approval, for the house to become a weekend retreat and place for prime ministers to entertain guests. Since 1921, when David Lloyd George became the first prime minister occupant, his successors have usually spent time there during their terms of office, and ministerial weekends at Chequers have become a part of British political life.
