Plan(e) Speaking: a multiplanar theory of spatial planning

I develop a new theory of spatial planning. This is a multiple, relational approach of dynamic complexity to understanding and working with contingencies of place, time and actant behaviours. Inspired by the planar philosophy of Gilles Deleuze, I offer the potential for multiple planes: several ¿ or perhaps one collectively preferred ¿ broad trajectories or `visions¿ of the longer-term future ¿ (Deleuzean planes of consistency or immanence) ¿ and shorter-term, location-specific detailed plans and projects with collaboratively determined tangible goals ¿ (planes of organization or transcendence). I explore what spatial planning practice could look like if it were to become along Deleuzean lines. I argue the case for performance-based planning rather than performance-measured, target-based master plans, discussing critical problems and issues for theory and practice.
