ABSTRACT The compact city agenda aims to deliver sustainable future urban form. However, as with all planning, there is contestation. While built form and housing have primacy, cities need space for hard and soft infrastructural systems, including natural systems that, until recently, have been taken for granted but are diminishing through poorly planned densification. Nowhere is this more evident than in the suburbs, where lot-by-lot redevelopment is significantly reducing open space and tree canopy. Infill developments are not producing the benefits expected from compact cities; they are increasing strain on the grey, blue, and green infrastructure. This paper highlights limited intent in local planning regulations to promote anything other than business as usual, which, in the Australian context, is single lots becoming 2–4 subdivisions. While planning schemes can regulate negative externalities, they do not consider this when taken as a whole, across a redeveloped neighbourhood predominantly consisting of housing, and are not using the redevelopment opportunities to build a more resilient future for local areas. This paper builds on the Australian greyfield literature by showing how statutory amendments can promote precinct scale development, working across multiple lots to deliver housing concurrently with greater levels of amenity for existing and future residents. KEY POINTS Infill housing development on single lots is reducing local amenity while not making the fullest use of the land for housing supply. Site assembly precincts are critical for higher yield, higher amenity, urban redevelopment. Strategic policy alone will not deliver the solutions; statutory mechanisms for doing so are critical. This paper presents a fully worked statutory response to the issue, highlighting the method for developing the scheme and the future work necessary for delivering site-assembly precincts at council level.
