SUMMARY
After the Second World War, Modernism started to debate his continuity or crisis. This led many architects and critics to formulate theories and take up breaking disciplinary attitudes against that time. One of them was the English architect, urban planner and landscape designer Peter Shepheard who developed a professional, theoretical and academic career where the concept in between got relevance as one of the defi ning keys of the architectural design in the second half of the twentieth century. To Shepheard modern design should be the encounter between architecture, urbanism and landscape. This claim was preceded by different types of architectural works, urban projects, articles and publications on landscape design and garden which made him a leading voice in the British context.Shepheard encouraged landscapers architects to convince themselves that the three disciplines converge into one. The responsibility of the young profession of landscape architecture was to assume the challenge for the architectural, urban and landscape design as a whole and in the search for and defi nition of intermediate spaces between the architecture and the landscape.
