After graduating with first class honours and the Donaldson medal from University College London, Brian was taught by Zaha Hadid at the Architectural Association and was awarded an honours diploma.

Brian joined Zaha Hadid’s practice in its early days when the team was small and led projects for Halkin Place (1984), Trafalgar Square Grand Buildings (1985) and Tokyo International Forum (1989). He became an Associate at Mittelman Caradoc-Hodgkins, responsible for building the Sky BSB headquarters, health clubs, warehouse conversions and residences. Returning to Zaha Hadid's practice, he was Project Architect for the £50 million Cardiff Bay Opera House (1994), the 25,000 sqm home to Welsh National Opera, and Co-Project Architect for the 34,000 sqm Art and Media Centre in Düsseldorf (1992), and worked on the Victoria and Albert Museum Extension (1996).

In 1996, Brian set up his own practice to concentrate on designing and building for private clients.
