Berkeley House on Piccadilly was named after John Berkeley, 1st Baron Berkeley of Stratton who had purchased its land, and that surrounding it, shortly after the Restoration of the Monarchy in 1660. In 1696, the Berkeley family sold the house and grounds to the 1st Duke of Devonshire (who renamed it Devonshire House) on condition that the view from the rear of the house should not be spoiled. Berkeley Square was laid out to the rear of the house in the 1730s; because of the conditions of sale, houses were only built on the east and west sides. The west side still has various mid-18th-century buildings and the east side now contains offices including Berkeley Square House.
