The Dorchester is a leading luxury hotel and a very famous one on Park Lane in Mayfair, London, overlooking Hyde Park. It has a reputation for providing hospitality for the rich and famous and is very popular among the high class people. The Dorchester Hotel opened on 18 April 1931 and was created by Sir Malcolm McAlpine and Sir Frances Towle. During the construction, the use of reinforced concrete allowed the creation of large internal spaces without support pillars.

The construction was carried out by Sir Robert McAlpine and was completed in 1931. In the Second World War, its modern construction gave the hotel a reputation of being a very safe building. Cabinet Ministers such as Lord Halifax and Duff Cooper stayed there during this time. Winston Churchill, when he lived in the hotel, had a wall built to add privacy to his balcony and it still exists today. The Dorchester is managed and owned by the Dorchester Collection; a collection of seven luxury hotels in the England, the United States, France, and Italy. It was organized in 1996 to manage and run the hotel interests of the Brunei Investment Agency.
