Dolphin Square is a block of private flats and business complex built near the River Thames at Pimlico in London, between 1935 and 1937. At one time, the huge development was home to more than 70 MPs, and at least 10 Lords. At the time of its construction the development of 1,250 up-market flats was billed, according to Sir Nikolaus Pevsner as the "largest self-contained block of flats in Europe" and, to an extent, their design has been a model for later municipal developments.
