Kennedy has 25 years experience in helping clients to define their accommodation needs using a variety of analytical and design tools combined with option analysis. In his early career he worked at Sheppard Robson Architects on a range of large scale projects. He led the design team for the new Southlands College at the University of Roehampton. He led feasibility studies for English National Opera at the London Coliseum. He worked on Somerset House with Drivers Jonas. He collaborated with Herzog and DeMeuron on Tate Modern, scoping client/design team workshops and looking at the Tate's operational requirements.
Since setting up the practice in 1998 he brought this experience to bear on projects for the RAF Museum, the Tank Museum, Bletchley Park and the Etches Collection while working on historic buildings and projects for private clients in parallel.
