Buckinghamshire [SEP] Introduction
In this area older buildings are often made from local flint and red brick. Many parts of the county are quite affluent and like many areas around London this has led to high housing costs: several reports have identified the market town of Beaconsfield as having among the highest property prices outside London. Chequers, a mansion estate owned by the government, is the country retreat of the incumbent Prime Minister. To the north of the county lies rolling countryside in the Vale of Aylesbury and around the Great Ouse. The Thames forms part of the county's southwestern boundary. Notable service amenities in the county are Pinewood Film Studios, Dorney rowing lake and part of Silverstone race track on the Northamptonshire border.
