site was that of a Sir William Blake, around 1624. The next owner was Lord Goring, who from 1633 extended Blake's house and developed much of today's garden, then known as Goring Great Garden.Unbeknown to Goring, in 1640 the document "failed to pass the Great Seal before King Charles I fled London, which it needed to do for legal execution". (It was this critical omission that helped the British royal family regain the freehold under King George III.)
The improvident Goring defaulted on his rents; Henry Bennet, 1st Earl of Arlington obtained the mansion and was occupying it, now known as Goring House, when it burned down in 1674. Arlington House rose on the site — the southern wing of today's palace — the next year, and its freehold was bought in 1702.
The house which forms the architectural core of the present palace was built for the first Duke of Buckingham and Normanby in 1703 to the design of William Winde. The style chosen was of a large, three-floored central block with two smaller flanking service wings.
Buckingham House was eventually sold by Buckingham's descendant, Sir Charles Sheffield, in 1761 to George III for £21,000.The house was originally intended as a private retreat for the royal family, and in particular for Queen Charlotte, and was known as The Queen's House. St. James's Palace remained the official and ceremonial royal residence; indeed, the tradition continues to the present time of foreign ambassadors being formally accredited to "the Court of St. James's", even though it is at Buckingham Palace that they present their credentials and staff to the Queen upon their appointment.
