Sunningdale is a village and a civil parish in the Royal Borough of Windsor and Maidenhead. It takes up the extreme south-east corner of Berkshire, England and is adjoined by green buffers including Sunningdale Golf Club and Wentworth Golf Club. Its northern peripheral estates adjoin Virginia Water Lake.
Sunningdale adjoins Surrey, and is east of Sunninghill from which it takes its name. It is south of Virginia Water Lake. It is centred west south-west of Charing Cross, London. The nearest major towns are Bracknell, Camberley, Staines upon Thames and Woking. It is connected to two of these by the A30 old trunk road. Sunningdale railway station is on the Waterloo to Reading line.
The present-day civil parish of Sunningdale came into existence in 1894 under the provisions of the Local Government Act 1894; the village had previously been part of Old Windsor.[2] It was, until 1995, partly in Berkshire and partly in Surrey. The Surrey area of the village, known as Broomhall, was also split between the boroughs of Surrey Heath and Runnymede. This original arrangement caused problems and was resolved after much consultation locally between the two county councils, three borough councils and four parish councils. As a result, its former Surrey neighbourhoods merged with the rest in the Royal Borough of Windsor and Maidenhead, in the Royal County of Berkshire (which became a non-administrative county in 1995). The area is popular with professional golfers due to its adjoining green buffers including Sunningdale Golf Club and Wentworth Golf Club.
Charters is a Grade II-listed art deco mansion, built in 1938 for the industrialist Frank Parkinson by the architects Adie, Button and Partners. It was built on the site of an earlier country house built in the late 1860s by William Terrick Hamilton. Parkinson's guests included Winston Churchill and the Duke and Duchess of Windsor. In 1949, the house was bought by Sir Montague Burton. It later became a corporate headquarters and has since been redeveloped as an apartment complex and spa.
