Rosemary Yallop is an architectural historian specialising in the domestic architecture of the long Georgian period. She received her doctorate from the University of Oxford for her work on John Nash and the Vernacular Italianate villa idiom. She has a particular interest in the architectural Picturesque which united house and setting: its varied aesthetic, its impact upon the designed landscape and its legacy in the design of the new villa suburb from the Regency era onwards.

Rosemary has published and lectured on a variety of subjects, including John Nash and the villa rustica, the Picturesque aesthetic, the villa as vessel for middle-class life, the evolution of Victorian suburb, the career of Robert Lugar, and the work of George Stanley Repton. Current research includes the nineteenth-century British Castle Revival, and the careers of provincial architects in Devon, where she lives. For nine years she served as Trustee and Vice-Chairman of the Georgian Group, and is also a former trustee of Pitzhanger Manor and of the Devon Gardens Trust. She is a course leader and lecturer for the Victoria & Albert Museum, is available for lectures, teaching and comment, and will undertake house and estate histories.
