Beyond small lot subdivision: towards municipality-initiated and resident-supported precinct scale medium density residential infill regeneration in greyfield suburbs.

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.

摘要

由于限制性的土地使用管制，已建成的中郊（灰色地带）新建住房的土地供应被“锁定”，因为那里存在大量的城市填充潜力. 因此，大多数住宅填充物都是零碎的、次优的小地块细分. 本文概述了实施一种新的发展模式——灰地片区更新——的关键方面，该模式要求对市政战略规划、新的分区发展计划、创新的中密度住宅设计进行变革，以及业主集群，他们可以被激励利用地块合并价值提升来克服小地块、分散、填充的负外部性.
