In this paper, we highlight some of the challenges associated with strategic spatial planning, including long-time frames, limited control, translation and implementation gaps. We then explore how tactical urbanism might, in theory, address these s given its emphasis on small-scale, immediate, experimental action for long-term change. Our research with a Charter-based, principles-led, action-oriented network is then used to test these possibilities in practice. We conclude that tactical urbanism can be considered the antithesis of, complement to, or antidote depending on the disposition of planning authorities.
