Highpoint I was the first of two apartment blocks erected in the 1930s on one of the highest points in London, England at Highgate. The architectural design was by Russian-born architect Berthold Lubetkin, the structural design by Danish engineer Ove Arup and the construction by Kier. Highpoint I was built in 1935 for the entrepreneur Sigmund Gestetner, but was never used for its intended purpose of housing Gestetner staff. One of the best examples of early International style architecture in London, this block of 64 flats was very innovative in its day. When the building was completed, it became widely renowned as the finest example of this form of construction for residential purposes. When Corbusier himself visited Highpoint in 1935 he said, "This beautiful building .... at Highgate is an achievement of the first rank." And American critic Henry Russell Hitchcock called it, "One of the finest, if not absolutely the finest, middle-class housing projects in the world." In 1970 this reputation gained official recognition when both Highpoint blocks were classified Grade I within the historic buildings listing programme. The second Lubetkin building in the same style, Highpoint II, was completed on an adjoining site in 1938. Architectural historian Dan Cruickshank selected Highpoint as one of his eight choices for the 2002 BBC book The Story of Britain's Best Buildings .
