Carl Pruscha's passionate manifesto for the preservation of the traditional habitat and for safeguarding the regional vernacular culture deeply concerns present architectural and environmental planning. Pruscha demonstrates his holistic concept of vivid preservation and change in three regional planning case studies in Nepal, Bhutan and Tibet. His conclusions become an integral issue for the architect's own construction activity in Nepal. Pruscha's Himalayan photographs present the particular symbiotic relationship of environment and architecture and puts the viewer amidst, where he might perceive "the sophisticated and sensitive responses given by generations of Himalayan people".
