Euston Hall, were the work of a later owner and architect. The neoclassical entrance lodges were a later addition, by Sir John Soane. In 1743, Brettingham began work on the construction of Hanworth Hall, Norfolk, also in the Palladian style, with a five-bay facade of brick with the centre three bays projected with a pediment. In 1745, Brettingham designed Gunton Hall in Norfolk for Sir William Harbord, three years after the former house on the site was gutted by fire. The new house of brick had a principal facade like that of Hanworth Hall, however, this larger house was seven bays deep, and had a large service wing on its western side. His commissions began to come from further afield: Goodwood in Sussex and Marble Hill, Twickenham. In 1750, now well-known, the architect received an important commission to remodel Euston Hall in East Anglia, the Suffolk country seat of the influential 2nd Duke of Grafton. The original house, built circa 1666 in the French style, was built around a central court with large pavilions at each corner. While keeping the original layout, Brettingham formalised the fenestration and imposed a more classically severe order whereby the pavilions were transformed to towers in the Palladian fashion (similar to those of Inigo Jones's at Wilton House). The pavilions' domes were replaced by low pyramid roofs similar to those at Holkham. Brettingham also created the large service courtyard at Euston that now acts as the entrance court to the mansion, which today is only a fraction of its former size. The Euston commission seems to have brought Brettingham firmly to the notice of other wealthy patrons. In 1751, he began work for the Earl of Egremont at Petworth House, Sussex. He continued work intermittently at Petworth for the next twelve years, including designing a new picture gallery from 1754. Over the same period his country-house work included alterations at Moor Park, Hertfordshire; Wortley Hall, Yorkshire; Wakefield Lodge, Northamptonshire; and Benacre House, Suffolk. London townhouses From 1747, Brettingham operated from London as well as Norwich. This period marks a turning point in his career, as he was now no longer designing country houses and farm buildings just for the local aristocrats and the Norfolk gentry, but for the greater aristocracy based in London. One of Brettingham's greatest solo commissions came when he was asked to design a town house for the 9th Duke of Norfolk
