Our Team


  Rupert Hilton

Historic Building Surveyor/Director

Rupert spent much of his youth growing up in the shadow of Clitheroe Castle, Lancashire, which proved to be the catalyst for a lifelong interest in the historic built environment.

He graduated with a first-class degree in Design, Development & Regeneration from Nottingham Trent University in 2006, before completing his master’s degree in Conservation of the Historic Environment from the University of Reading.

Having worked for some of the most well-respected conservation companies in the UK, Rupert quickly established himself as one of the most versatile, qualified and capable conservation practitioners in the country, before founding Janus Conservation in January 2020.

Rupert is one of only a handful of practitioners in the UK to hold full conservation accreditations with the Royal Institution of Chartered Surveyors (RICS), the Chartered Institute of Building (CIOB) and the Institute of Historic Building Conservation (IHBC).

He is now particularly interested in ‘retrofit’ and making responsible and technically compatible improvements to the energy efficiency of historic buildings and is a qualified Retrofit Designer for Pathway C (High Risk Schemes) under PAS 2035 




Katherine Harrison

Senior Heritage & Planning Consultant

Katherine is a Full Member of the IHBC and has a background as a senior conservation officer. This has given her a unique perspective of the planning side of conservation whilst her Masters in Buildings History from Cambridge has provided her with research skills – both proving a huge advantage when providing advice to clients.

She is experienced in assessing the potential impact of schemes on the significance and setting of a wide variety of heritage assets, ranging from vernacular properties, eccleisastical buildings, country estates, and archaeological assets. She has also written over 20 Conservation Area Appraisals whilst working for Local Authorities.

Katherine believes that researching buildings to gain an understanding of their historic background and heritage value allows for the most appropriate and considered changes to be made.

She also enjoys understanding how areas have developed over time and being a part of their continuing evolution with new sensitively designed schemes, showcasing the best of contemporary architecture whilst also enhancing the historic environment.
