Julian has worked on medieval houses, castles, cathedrals, and country houses, and is interested both in the archaeology of buildings and the link between documentary history and extant remains of the past. With an interest in urban and rural landscapes, he has examined the relationship between places, their physical remains and written history, and has published numerous studies.

He often undertakes investigation and assessment of historic buildings and places for planning purposes, and has been involved in a series of Conservation Plans for national monuments (castles, country houses and cathedrals), for National Trust, English Heritage and others, and planning assessments of greater and lesser buildings of all types and periods.

Julian is involved in teaching and outreach activities, and is a frequent public speaker on many aspects of the historic environment. He is a Fellow of the Society of Antiquaries (FSA), has often appeared as an expert witness at public inquiries and planning hearings. He is Chairman of the Chichester Cathedral Fabric Committee (FAC).

Jon has worked in Oxford Archaeology’s Historic Buildings Department since 1998, and he particularly specialises in the investigation of post-medieval and modern buildings. He holds a BA in Architecture, as well as a Masters Degree in Industrial Archaeology from the Ironbridge Institute, and he is a Member of the Chartered Institute for Archaeologists (MCIfA).

Jon helps to coordinate the overall department’s workload, as well as manages individual projects, undertakes on-site investigations, writes reports and tenders for new work. He undertakes a wide range of projects, including conservation management plans, impact assessments, environmental statements, large-scale building recording prior to developments, and small-scale assessments to assist in planning applications. While with OA, Jon has worked on scheduled Cold War sites, Royal Palaces, airfields, industrial complexes, gunpowder factories, grand country houses, and much more humble dwellings.

Jamie Quartermaine (BA Hons, Surv Dip, MCIfA) has been a project officer and then project manager at OA North since 1984, and has considerable experience of all aspects of commercial archaeology. He has specialised in landscape recording and building surveys, and is one of the leading authorities in the study of archaeological landscapes. He has published monographs on the archaeological landscapes of the Lake District and the archaeology of Thomas Telford’s Holyhead road through North Wales.

Jamie is a qualified land surveyor, and has striven to develop landscape and building recording techniques, which vary from the introduction of GPS techniques in the early 1990s, to laser scanning, LiDAR, GIS and, more recently, modern photogrammetry techniques. He has extensive experience of training in all aspects of digital recording and was involved in the training of a Nepalese survey team to undertake a comprehensive recording programme of a large 17th-century palace on the outskirts of Kathmandu.
