Her design solutions are logical, contextual and maintain a high standard of architectural quality.

Her portfolio includes major university and cultural projects, particularly within the collegiate setting of the University of Oxford.

She has led and contributed to conservation plans and heritage statements, working closely with conservation authorities and funding bodies to deliver innovative architecture within historic settings aligned with sustainability targets such as LETI and the RIBA 2030 Climate Challenge.

Mandy is currently overseeing several projects in Oxford, including the Hertford College Library development and the refurbishment of Nuffield College, while also acting as Conservation Architect for projects such as the refurbishment of Goodenough College in London.
