Our Team


Rupert Hilton


Rupert spent much of his youth playing 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 working at Atkins Global in both Leeds and London, where he quickly moved from general surveying and project management to the company’s heritage division. At the same time, he completed 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 and qualified and capable conservation practitioners in the country, before starting Janus Conservation in January 2020.

Rupert is one of the few practitioners to be conservation accredited with both the Royal Institution of Chartered Surveyors (RICS) and the Chartered Institute of Building (CIOB) as well as being an associate member of the Institute of Historic Building Conservation (IHBC).

Past and current clients include, The Royal Household, National Trust and Historic England.

Virginia Polignano

Senior Architect

Virginia joined Janus Conservation in February 2021 as Senior Architect.
She studied and completed her architectural training at the Polytechnic of Bari, Italy, before completing her training in the UK to become a RIBA chartered Architect.

Prior to joining Janus, Virginia gained a broad range of experience across residential and commercial sectors, working with both private homeowners and developer clients in London and the South East.

Through this more mainstream work, she developed a passion for conservation and finding design-led creative solutions that breathe new life into heritage assets, respecting and enhancing their significance.

Virginia is currently completing an MA in Conservation of Historic Environment at Birmingham City University and is working towards becoming an Architect Accredited in Building Conservation (AABC) as well as a full member of the Institute of Historic Building Conservation (IHBC).


Oliver Sharpin

Historic Building Surveyor

Oliver has had an interest in history from a young age. He graduated with a degree in history from the University of Portsmouth before returning to study for an MSc in Historic Building Conservation where he graduated in 2018.

Following this, he worked for a prominent surveying and historic building repair company in the north of England where he was exposed to a range of construction types including industrial buildings, churches & residential properties.

Oliver joined Janus in September 2020 and is currently building on his previous experience with the intention of becoming a full member of the Institute of Historic Building Conservation.

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.
