Susan's practice is focussed on building and engineering-related matters. Before coming to the Bar, Susan qualified and practised as an architect. Her architectural experience mainly comprised medium to large-scale commercial projects, in particular hotels and retail, and included being both office and site-based. She has practical experience of acting as a certifying architect in traditional contracting arrangements, of design and build procurement acting for employers, and a developer/contractor joint venture converting commercial offices to residential. She finds her experience of the construction industry of particular assistance in dealing with expert evidence on technical matters.

Susan has given seminars to other practitioners on subjects within her field of practice. She occasionally leads professional conduct teaching sessions at the Inns of Court School of Law, and regularly speaks about architect's liabilities to student architects undergoing their professional practice training. She also acts as an external tutor to students undertaking the MSc in Construction Law and Arbitration at Kings College London.

Susan contributes a chapter to Emden's Construction Law on the subject of variations. She is a case note editor for the Construction Law Journal, and regularly writes the Journal's editorial.
