Before moving to the Wilhelmstraße the British mission used, among others, the Building Leipziger Platz 12 and the Dutch Palace, this from 1797 to 1803. The original building at 70 Wilhelmstraße, known as the Palais Strousberg and designed by August Orth, was built in 1868 by the railway magnate Bethel Henry Strousberg. In December 1884 the United Kingdom bought the site after renting it for some years after Strousberg's bankruptcy and the subsequent sale of the building to Hugo zu Hohenlohe-Öhringen in 1876. Wilhelmstraße was then a centre for the German government, being the location of the Imperial Chancellery and the Foreign Ministry. When diplomatic relations were broken off at the outbreak of World War I the building stood empty. Surviving a fire during the upheavals of the 1919 revolution, it was reoccupied in 1920 when Edgar Vincent d'Abernon became Ambassador. At the beginning of World War II relations were broken off again. The building was heavily damaged by Allied bombing during the war and was demolished in 1950. The title to the land nevertheless remained in the possession of the British state.
Upon reunification in 1991, the German government returned the seat of government from Bonn to Berlin. Accordingly, the British government decided to reoccupy the Wilhelmstraße site, despite the German Foreign Office no longer being located in this street. An architectural competition was held, and won by the practice of Michael Wilford and Partner. Ground was broken at the site on 29 June 1998 by Derek Fatchett MP, and the new building opened by Queen Elizabeth II on 18 July 2000.
Architecture
The British embassy is the first, and to date, only embassy in Germany to be built under a Private Finance Initiative. Arteos, a Bilfinger Berger owned special purpose entity, financed and were to operate the embassy building for 30 years. A further 30-year extension is possible, following which the building will revert to British government ownership. In December 2006 Bilfinger sold their interest in the embassy to the UK firm Secondary Market Infrastructure Fund. Conscious of the necessity for modern embassies to forge good and open relationships with the German public, Wilford endowed the main floor with a café, library and restaurant. The security zone used to begin on the fourth floor but, with the perceived increased risk from terrorists, the site is now totally secured, and the intended public spaces are no longer freely accessible.
