A new choice but not newcomers

Mary has over 22 years’ experience as a landscape architect. She has co-authored IEMA guidance relating to the integration of design and EIA, and Landscape Institute guidance on the use of visualisations and contributed to guidance regarding residential visual amenity assessment.


Mary specialises in providing landscape and visual impact assessments and is an experienced expert witness, having provided support to Inquiry witnesses for many years and acted as an expert witness herself in relation to wind projects, roads, residential and commercial development and solar farms. Her assessment work includes many housing developments; solar farms; infrastructure projects and distribution sites; wind projects across the UK; and the Arcelor Mittal Orbit sculpture. Mary is currently a member of the Landscape Institute GLVIA Advisory Panel and the Scottish Renewables Onshore Wind Policy Group.
