late 1930s, with many houses built by Tarrant Builders Ltd, with Tarrant's son Percy as one of the directors; but again stopped during World War II when the need arose to build high-density housing close to Virginia Water railway station. Wentworth Subterranean Bunkers With the outbreak of World War II, Wentworth Estate was selected as an alternative seat of government and a rural command post, offering fewer security problems and more resources than the London Cabinet War Rooms (see also Cabinet War Rooms - Military Citadels under London. A subterranean bunker and tunnel system, now sealed and covered by car parks, was built near the Clubhouse. Designed by Harley Dalrymple-Hay, it was constructed in 1939 and consisted of two diameter parallel tunnels made from cast iron London Underground tube segments with a diameter service tunnel running between them. The bunkers were occupied by the GHQ Home Forces, and later the 1st Signal Regiment. The bunkers were vacated in December 1944.(See also) Post-war Post-war development picked up considerably, and by 1960 most of the available land was already used. Planning and amenities In 1962, a committee of residents and the company promoted a private act of Parliament, and on 31 July 1964 the Wentworth Estate Act was given Royal assent. The Act established the Wentworth Estate Roads Committee, which appoints its members on advice from the Wentworth Residents' Association. The Wentworth Estate is laid out across 700 hectares (1750 acres) and forms one of Europe's premier residential areas. Within the estate borders are a mixture of public and private roads, footpaths and open areas. It adjoins along a long border the long row of its village's shops, restaurants and other amenities, which is laid out upon similar lines but has many 21st century converted mansion and newly built apartments. The River Bourne runs through the area which has a population of 5,895. Transport Road Wentworth is just outside the ring of the London Orbital with a junction north. Routes from the west of the estate lead into Berkshire and towards Camberley and the Bagshot junction of the M3, which links to Southampton and to the A303. Rail Wentworth is adjoined to its south and east by a major stop and minor stop railway station on the London Waterloo to Reading Line: Virginia Water and Longcross respectively. Air Wentworth is south-west of Heathrow Airport; in private aviation Fairoaks Airport is south, accessible
