Caerleon is built upon the remains of the Roman town of Isca, once garrisoned by 5,500 soldiers, and is a major site for Roman archaeology. This new house is located in the heart of the Roman remains, in between the Roman Legion Museum and the Baths, in the garden of a Grade II listed Georgian house, No. 6 High Street. The new house is designed in the form of a long stone barn, reflecting the pattern of its surroundings, but with a crisp white modern wing extending across towards the old stone barn alongside and partly screening the 1960’s bungalows to the rear of the site. The ground floor has a sequence of connecting spaces overlooking the garden and culminating in an open suntrap courtyard set in behind the stone boundary wall to the rear of the old house. The new house sits comfortably in its surroundings and, with the new shared entrance courtyard, creates a more harmonious and structured relationship with the High Street.
