HELLO ARCHITECTURE is a visionary illustrated book that reframes architecture not as the design of buildings, but as a lived dialogue between culture, creativity, technology, and sustainability. Using an original acronymic framework - ARCH I TEC TURE - the book reveals architecture as a holistic discipline that shapes our identity, our cities, and our future. This is not a technical book about plans and elevations, nor a collection of glossy architectural monographs. It is a highly readable, deeply human exploration that speaks to: ¿ architects and designers ¿ students and educators ¿ urbanists and planners ¿ sustainability thinkers ¿ readers passionate about how we live Like Sapiens for anthropology or A Pattern Language for design culture, HELLO ARCHITECTURE offers a grand narrative: how architecture has evolved, what it means today, and how it can guide a sustainable future. The approach is global, inclusive, interdisciplinary, and richly illustrated - crafted for a world reshaping itself through climate urgency, digital transformation, and cultural complexity.
