The Inhabitable Spatial World argues that spatial computing has failed not because of inadequate hardware, insufficient investment, or immature technology, but because it lacks the constitutional foundation that enabled every previous successful computing paradigm to scale.

The book introduces a first-principles framework for designing inhabitable spatial environments, built around twelve constitutional laws derived from human perception and cognition. It establishes a precise professional vocabulary for the field, proposes a constitutional architecture for governing AI within spatial environments, defines an ethical rule engine that removes manipulation from system design, and presents Dream Code, a constitutional programming language for building compliant spatial worlds.

Drawing from design theory, human cognition, governance, ethics, and systems architecture, the book provides designers, researchers, executives, policymakers, and technologists with a rigorous framework for evaluating, constructing, and regulating the next generation of immersive environments.

At its core, the book contends that spatial computing cannot become a genuine civilisational platform until its constitutional layer exists—and proposes that layer in full.
