John Carter’s fervour as a recorder and polemicist for Gothic architecture has been debated since his lifetime, but his classical designs have attracted less interest. However, these give some insight into the influences upon aspiring young Georgian architects, as Carter was in the 1770s. His two sets of designs for Bywell Hall, Northumberland, the first published in the Builder’s Magazine in 1776, and a more detailed portfolio now in a private collection, are presented together for the first time. This is an opportunity to examine Carter’s early ideas and his thoughts on the appropriate styles to be employed for public, domestic and ecclesiastical buildings. Analysis of Carter’s designs demonstrates his desire to create impressive interior spaces, but poor consideration of the practicalities for family and servant life in country houses. Carter’s preference for Gothic over classical architecture, combined with humble origins and personality traits, prevented his aspiration to be an architect, but his drawing skills secured fame as one of the foremost architectural draughtsmen.
