About GDA



“The basis of my design philosophy – listen closely to what the client is saying. I maintain a personal involvement in all facets of a project, from site planning to interior details. It is “hands on” from concept discussions and sketch sessions with clients, to close observation of the work through completion.


I aim for design solutions that are lively and vigorous, full of historical and regional allusions, all in an engineered structure that is friendly with its site and surroundings. My clients provide the clues – usually a few key details or specifics, but sometimes elaborately thought-out arrangements, which we then develop into reality.”
