Senior Heritage Advisor
BSc (Hons), MSc, MA
Sarah began her career in heritage in 2008, undertaking a Bachelor of Science (Hons) in Property Development, for which she received a First Class degree in 2011. During her undergraduate studies Sarah developed a passion for historic buildings and their role in new development.
This led to a Master of Science in Historic Building Conservation undertaken over 2011-2012. Sarah went on to put this knowledge to use in the property market before being employed as a Landscape and Visual Impact Assessor and Planning Advisor at JBA Consultancy Services Ltd., in late 2012.
Between 2012 and 2016, Sarah wrote a number of articles concerning the relationship between heritage and development for magazines Rooftops and Future Build. She also provided photography toward National Trust publicity, whilst contributing towards ‘Introduction to Landscapes’, a book advising on Landscape and Visual Impact Assessment.
Sarah joined The Heritage Advisory in 2016 as Heritage Advisor and in 2017 obtained a further Master of Arts in Planning. Early 2018 saw her promoted to Senior Heritage Advisor, having by that time worked extensively in heritage planning, whilst utilising to considerable effect, her unique take on the place of heritage in planning and development.
Michael received his Bachelors of Architecture from the University of Southern California (2001-2006). He then went on to practise architecture across wider California whilst working for JTD Architects (2005-2007), Rivers & Christian Architects (2007-2014) and Studio One Eleven (2014-2019). He currently remains a registered architect.
Michael has worked on a high number of projects entailing aviation, retail, commercial, residential, and heritage. This has allowed him extensive experience of not only a wide variety of schemes, but also the very many component phases of architecture from conception through to completion, collaborating with numerous trades over the course of such a process.
More recently, Michael’s appetite for the past and the physical evidence of this has led him to focus an already accomplished career upon heritage and conservation. In 2019, he therefore went on to study at the University of York, and in 2021, obtained his MA in Conservation Studies (Historic Buildings), for which he obtained a Merit.
Combined with a growing passion for heritage and conservation, Michael’s studies in York have served to establish a new and exciting path in his career, and one which is lent unique insight by his previous years working in the wider industry of architecture and construction. Michael also volunteers with the York Civic Trust.
Whilst commenting on planning applications for the Trust, he has sought to guide and improve the designs and associated planning submissions of applicants so as to preserve and enhance the very many unique buildings and assemblies of the city, within what is not merely an intensively historic environment, but one that is continually evolving.
Michael looks forward to utilising his passion, drive, and knowledge in the built and historic environment to contribute toward the company’s goals of protecting and enriching the UK’s extensive heritage, whilst managing change there with care and creativity.
