with brick or stucco, plus new sash windows, to give the impression of modernity, despite the underlying structures remaining medieval. Pattern books and style guides The Neoclassical style was all the vogue throughout the 18th century, and many style guides were published to advise builders how their finished properties should look. Influential guides included Stephen Riou's The Grecian Orders (1768), and Batty Langley's A Sure Guide to Builders (1729), The Young Builder's Rudiments (1730 and 1734), Ancient Masonry (1736), The City and Country Builder's and Workman's Treasury of Designs (1740 and later editions), The Builder's Jewel (1741). Architects, designers, cabinet makers, stonemasons, and craftsmen published pattern books and style guides to advertise their ideas, thereby hoping to attract a lucrative clientele. The Adam style The work of the Adam brothers set the style for domestic architecture and interiors for much of the latter half of the 18th century. Robert and James Adam travelled in Italy and Dalmatia in the 1750s, observing the ruins of the classical world. On their return to Britain, they set themselves up with their older brother, John, as architects. Robert and James published a book entitled The Works in Architecture in instalments between 1773 and 1779. This book of engraved designs made the Adam repertory available throughout Europe. The Adam brothers aimed to simplify the rococo and baroque styles which had been fashionable in the preceding decades, to bring what they felt to be a lighter and more elegant feel to Georgian houses. The Works in Architecture illustrated the main buildings the Adam brothers had worked on and crucially documented the interiors, furniture and fittings, designed by the Adams. A parallel development of this phase of neoclassical design is the French Louis XVI style. The Adam style moved away from the strict mathematical proportions previously found in Georgian rooms, and introduced curved walls and domes, decorated with elaborate plasterwork and striking mixed colour schemes using newly affordable paints in pea green, sky blue, lemon, lilac, bright pink, and red-brown terracotta. Artists such as Angelica Kauffman and Antonio Zucchi were employed to paint classical figurative scenes within cartouches set into the interior walls and ceilings. The Adam's main rivals were James Wyatt, whose many designs for furniture were less known outside the wide circle of his patrons, because he never published a book of engravings; and Sir William Chambers, who designed fewer furnishings for his interiors, preferring
