This is particularly noticeable in the towers, which are slimmer and more refined than those of Mentmore Towers, the other great Jacobethan house built in the same era. Barry produced an alternative design in a more purely Italian Renaissance style, which was rejected by Lord Carnarvon. The external walls are decorated with strapwork designs typical of Northern European Renaissance architecture. The Italian Renaissance theme is more evident in the interiors. In the saloon, in an attempt to resemble a medieval English great hall, Barry's assistant Thomas Allom introduced a Gothic influence evident in the points rather than curves of the arches, and the mock-hammerbeam roof.
