1645–1731), the pre-eminent Scots architect of his day, and an early neo-Palladian whom Campbell called "the most experienced architect" of Scotland (Vitruvius Britannicus, ii). The somewhat promotional volume, with its excellently rendered engravings, came at a propitious moment at the beginning of a boom in country house and villa building among the Whig oligarchy. Campbell was quickly taken up by Lord Burlington, who replaced James Gibbs with Campbell at Burlington House in London and set out to place himself at the centre of English neo-Palladian architecture. In 1718, Campbell was appointed deputy to the amateur gentleman who had replaced Wren as Surveyor General of the Royal Board of Works, an appointment that Burlington is certain to have pressed, but a short-lived one. When Benson, the new Surveyor was turned out of office, Campbell went with him. Later volumes There are later volumes also published under the name ‘Vitruvius Brittanicus’, but they are not connected to Colen Campbell's work. In 1739 a volume was issued by Badeslade and Rocque, described as ‘Volume 4’. However, this had little in common with Campbell, comprising mainly topographical perspective views of houses (54 plates). Between 1765 and 1771, Woolfe and Gandon published their ‘Volumes 4 & 5’ (79 and 75 plates). They discounted Badeslade’s volume, believing their work to be a more correct continuation of Campbell, hence their numbering. The plates are indeed mostly plans and elevations of buildings largely in the Palladian style, most dating from after 1750. The various Volumes are fully described in Harris. Campbell's main commissions Wanstead House, Essex, c. 1713/4–20 (illustrated left). In the first volume of Vitruvius Britannicus, the most influential designs were two alternatives for a palatial Wanstead House, Essex, for the merchant-banker Sir Richard Child, of which the second design was already under way when the volume was published. (Campbell claimed that Wanstead House had Great Britain's first classical portico, but this accolade probably belongs to The Vyne, Hampshire.) Burlington House, London, 1717. Remodelled the front and provided an entrance gateway for Richard Boyle, 3rd Earl of Burlington (Remodelled in 1868 and the gateway demolished.) Stourhead, Wiltshire, 1721–24, as a seat for the London-based banker Henry Hoare. Wings were added in the later 18th century, and Campbell's portico was not executed (though to his design) until 1841. The famous landscape garden round a lake, somewhat apart from the house, was developed after Campbell's death, by Henry Flitcroft.
