This article focuses on Bramshill, Hampshire, one of the most important country houses of the early modern period. From 1605 Bramshill was the home of Edward la Zouche (1556–1625), 11th Baron Zouche – a major courtier during the reigns of Elizabeth i and James i – and was reworked in phases up to and just beyond his death. Based on rare-surviving documents from the 1630s as well as analysis of the house’s fabric, this article reconstructs Bramshill’s plan and interiors as they existed in the late Jacobean and Caroline years. It reveals the arrangement of two significant state apartments – for king and queen – and also the lodgings of the owner, his family and guests, as well as service areas. The rich source material additionally allows the furnishings to be analysed. By using Bramshill as an example, the article aims to shed light on English country houses of similar size and date. The early modern period is important as representing an apogee in the history of country house building – reflecting the ambition of owners such as Lord Zouche and the popularity of the royal progress. Visitors to Bramshill in the early seventeenth century included James i, Charles i and Queen Henrietta Maria.
