Conceived Space (Representations of Space)

Conceived space, or representations of space, is the dimension of Lefebvre's triad produced by those with institutional authority to design. It embodies the logic of whoever commissions it — the lord's power in the feudal castle, capital's efficiency in the factory, the planner's rationalism in the housing project. Its characteristic outputs are blueprints, zoning codes, specifications, and models. In the AI moment, the engineer's interface design — the decisions about responsiveness, context window, conversational register, architectural choices that shape every interaction — is conceived space operating at civilizational scale. The dimension is not inherently bad: all spaces require conception. The pathology is the dominance of conceived space over lived space, producing environments rational on the drawing board and uninhabitable in practice.
