Greyfield Precinct Renewal

Swinburne University 18 February 2016

SLIDE 2

Objective: Improving the performance of Residential Infill

A business as usual (knockdown/ rebuild) scenario Sub-optimal use of land in relation to:

Housing (low yield)
Green space
Energy/carbon footprint
Water conservation.

Regeneration scenario with lot amalgamation

Optimised land use, high quality design
Better yield (medium density)
Housing mix (types/size)
Zero carbon (distributed generation and

storage)

Water sensitive (stormwater harvesting)
Minimise area devoted to vehicles
Maximised green space
Landowners maximise investment through

collective sale

If 100% of high RPI properties are developed (only to existing densities), we almost double the dwellings by using precincts and land optimisation

Technical: Environmental and Financial Feasibility of Precinct Re-Design (ESP)

Economic viability: Our calculators indicate significant gains can be made through lot amalgamation - particularly in joint venture (landowner / developer) scenarios. [Missing

from Productivity Commission report: Housing Decisions of Older Australians, Dec 2015]

Environmental and Social Sustainability: ESP indicates significant sustainability and social gains can be made through lot amalgamation - particularly with LGA involvement in design and statutory regulation

SLIDE 9

Engagement: process and tools for Precinct Scale Renewal

Community Engagement – Town hall: Large scale engagements with all

residents. Recently completed in

Maroondah (in collaboration with housing strategy officers) and previously in Reservoir and Hampton (AHURI) Neighbourhood Engagement – Kitchen Table: Being prepared, in collaboration with Maroondah officers

SLIDE 10

Statutory and legal tools for greyfield precincts

Legal templates: Offering a variety of contractual templates for land owners to engage with precincts Financial options: establishing a range of financial options for residents Statutory tools: Currently working on identifying the regulatory issues that could prevent greyfield precinct redevelopment and how to overcome them.
