Influences The Netherlands provided William Bruce with many of his influences. He was in the Low Countries at a time when Italian Classicism was the height of fashion, and similarities have been observed between Bruce's work, particularly Holyroodhouse, and such buildings as the
Amsterdam City Hall (1648–65), the work of
Jacob van Campen, and
Maastricht's City Hall (1659–1664), by
Pieter Post. Alexander Bruce had married a Dutch woman with family ties to the
House of Orange, and it seems likely that he provided links to the Dutch artisans who worked on some of Bruce's projects. English influence is also visible in his work. His country houses took the compact Anglo-Dutch type as their model, as introduced into England by
Hugh May and Sir
Roger Pratt, but with Continental detailing, such as the
rustication on the façade at
Mertoun. Roger Pratt's
Coleshill House of 1660 is often cited as a model for Bruce's Kinross House. Konrad Ottenheym concludes that Bruce employed an "international style", which was fashionable in France, Holland, and England, and that he was pivotal in disseminating this style in Scotland. At Leslie, Bruce oversaw the works after Mylne's death, and probably made his own amendments. Panmure was demolished in the 1950s, and only a small part of Leslie House remains standing, following a fire in the 18th century. Bruce later advised
William Douglas, 1st Duke of Queensberry regarding his plans for
Drumlanrig Castle. The curving walls, a form later seen at Hopetoun, were a new innovation if Bruce did carry them out, possibly inspired by the work of the Italian
Gian Lorenzo Bernini. Internally, Bruce created a new layout of rooms, and it was for his continental-inspired internal planning, as much as his exterior design, that he was sought after as an architect. In 1670 the Duke of Lauderdale commissioned Bruce to remodel
Thirlestane Castle, his 16th-century
tower house in the Border country. Bruce, working with King's master mason
Robert Mylne, extended the building with new corner pavilions and a new entrance, and re-planned the interior. Lauderdale continued to employ Bruce, often working closely with Lord Haltoun, Lauderdale's brother, during the 1670s, on his homes at
Brunstane near Edinburgh, and Lethington (later renamed
Lennoxlove), as well as commissioning a design for new gates at his English property,
Ham House, near London, in 1671. At Ham Bruce may have had further involvement with the remodelling works going on there, under the direction of the English architect
William Samwell. While engaged at Thirlestane, Bruce also designed the nearby
Lauder Kirk, his only complete church. One of very few 17th century cruciform-plan churches in Scotland,
Holyroodhouse William Bruce's appointment as Surveyor General of the King's Works in Scotland was made chiefly for the purpose of rebuilding the palace of
Holyroodhouse. Aside from this project, he only carried out minor repairs to Edinburgh and Stirling Castles, and to the fortifications on the
Bass Rock. Charles I had intended to extend and rebuild Holyroodhouse, and plans had been drawn up in the 1630s. Nothing was done however, and in 1650 the palace was burnt out, destroying all but the west range. Bruce was contracted to design and oversee the works, with Robert Mylne acting as contractor. Bruce's plans were drawn up by Mylne, as Bruce himself apparently lacked the technical skills of architectural drawing. Charles II criticised Bruce's initial plans for the internal layout, and an improved scheme was eventually approved. Construction began in July 1671, and by 1674 much of the work was complete. Bruce built a second gothic tower to mirror the existing one built by
James V between 1528 and 1532, and created the courtyard block in a restrained classical style. Also in 1676, Bruce drew up plans for the completion of
Heriot's Hospital in Edinburgh, which had been started in the 1620s. His design, for the central tower of the south façade, was eventually executed in 1693.
Country houses His first commission for a new building was for the construction of Dunkeld House, and came from
John Murray, 2nd Earl of Atholl in 1676. In 1675, Bruce bought the estate of
Loch Leven from the
Earl of Morton. The estate included an old manor near
Kinross, as well as the ruins of
Lochleven Castle, famous as the jail of
Mary, Queen of Scots. After carrying out repairs on the old manor, and beginning to lay out the gardens, Bruce began work on his new home,
Kinross House, in 1686, employing master mason Thomas Bauchop. The
Palladian building bears some resemblance to Roger Pratt's Coleshill House of 1660 (demolished), but with features Bruce derived from French sources. These features, ultimately classical and Italian in origin, include the rusticated basement stonework, and the
giant order of
corinthian pilasters, the latter possibly deriving from Bernini's first designs for the
Louvre Colonnade. Following Bruce's fall from favour, he found himself increasingly in debt, which delayed the completion of the house until 1693. Kinross was one of the earliest Palladian-style country houses in Scotland, and was recognised as one of the finest buildings in the country;
Daniel Defoe described it as "the most beautiful and regular piece of Architecture in Scotland", and
Thomas Pennant called Kinross "the first good house of regular architecture in North Britain". Despite William Bruce's fall from political favour, and his intermittent imprisonment, he continued to practice. During the 1690s he completed Hill of Tarvit (1696), Craighall (1697–99) in Fife, and
Craigiehall (1699) near Edinburgh. The latter, built for
William Johnstone, 1st Marquess of Annandale, still stands, and is used as the
British Army's Scottish headquarters. From 1698 he was working on a new house for the young
Charles Hope, later 1st
Earl of Hopetoun.
Hopetoun House, near Edinburgh, was completed in 1702, and represents Bruce's grandest country house design. The master mason was again Thomas Bauchop, and the inspiration was again Anglo-Dutch, with French
rustication. The bulk of Bruce's work is now obscured by 18th-century remodelling, carried out by
William Adam. Bruce was commissioned again by Hopetoun in 1708, to build a private aisle at
Abercorn Kirk. The Hopetoun Loft overlooks the interior of the kirk, and connects to a retiring room with an oval "squint" giving a view of the pulpit. In 1702 Bruce was commissioned by the burgesses of
Stirling to design the new
Stirling Tolbooth. Bruce provided only sketch plans, which were executed by local masons between 1703 and 1705. Bruce's last country houses were Harden House (now known as
Mertoun House), built for the Scotts in the
Borders, and his smallest house,
Auchendinny in
Midlothian. His final work, built from 1706 to 1710, was the
House of Nairne, for the Jacobite
William Murray, 2nd Lord Nairne. The house was not completed until two years after Bruce's death, and the extent of his involvement is unclear. Nairne House was demolished in 1760, although the cupola was retained and installed on the roof of the
King James VI Hospital in nearby
Perth. ==Legacy==
