After setting up a landscape team within a large London architectural practice in 1980, John established his own landscape practice in the Cotswolds in 1984 and was joined by Martin Portus two years later.  A keen interest in the design of the wider living environment has involved John in a broad range of landscape design as well as architectural and interior design—from pavilions to opera houses. John encourages observation and drawing skills within the practice as a means not only to realise imaginary concepts but to be able to present these to others.  John has worked for public authorities and for commercial, institutional and private clients including historic estates, universities, healthcare, church and leisure clients. John has a special interest in garden design which he feels brings together all the skills of the landscape architect into individual projects. Completed gardens range from the small to the enormous and complex, including lakes, fountains, grass amphitheatres and specially commissioned sculpture.
