ABSTRACT Land supply for new housing in the established middle-suburbs (greyfields), where much urban infill potential exists, is “locked up” due to restrictive land-use regulation. As a result, most residential infill is occurring as fragmented, sub-optimal small lot subdivision. This paper outlines critical aspects in implementing a new development model – greyfield precinct renewal – which requires transformative change in municipal strategic planning, new zoning development schemes, innovative medium-density dwelling designs, and clusters of property-owners who can be motivated to capitalise on lot-consolidation value-uplift to overcome the negative externalities of small lot, fragmented, infill.

超越小规模细分：在格雷菲尔德郊区实现市政主导和居民支持的区域规模中密度住宅填充物再生。

摘要由于土地使用的限制规定，已经存在很多城市填充潜力的已建立的中郊区（灰田）的新住房土地供应被“锁定”。结果，大多数住宅填充物都是零散的，次优的小地块细分。本文概述了实施新的开发模式（灰田区更新）的关键方面，这需要市政战略规划，新的分区开发方案，创新的中密度住宅设计以及可以激发利用资本的资产所有者集群的变革批量合并增值，以克服小批量，分散，填充的负面外部性。
