A converted dairy farm will open next month as the new home of one of Europe's best-known philanthropic organisations, the Rothschild Foundation.

Windmill Hill is located on the estate of Waddesdon Manor, near Aylesbury Buckinghamshire, the house built by Baron Ferdinand de Rothschild in 1877 to contain his art collection. It is now a National Trust treasure.

The new centre, designed by Stephen Marshall Architects, will house the archives of the estate and family papers of the Rothschilds, as well as the foundation offices.

It will also host debates and discussions on a host of issues ranging from green technology to the Middle East.
