Demonstrator 3: Housing Affordability and Land Administration
Co-led by Dr Mohsen Kalantari, Prof. Abbas Rajabifard, Centre for Spatial Data Infrastructure and Land Administration, Dr Jennifer Day and Dr Piyush Tiwari, Faculty of Architecture, Building, and Planning.
The focus of this project is to demonstrate the link between availability of developable land and space and affordable housing development. This requires a rigorous analysis of residential land development potential that is essentially linked to datasets such as land value and capital improved value information (Agunbiade et al 2011).
The core analysis is intended to determine Residential Development Potential Index (RDPI) for a cross section of the NW Corridor region. Spatially enabled tools provide this (Kalantari 2007). The tool aims to provide ways of analysing and communicating, the challenges and prospects of discovering developable land for housing production.
This work explores the links between land supply and housing affordability. The following questions summarise the public-policy issues that will be illuminated by this work:
- Will effective and efficient integration across the land administration functions (DSE, Land Victoria, DPCD, Local Governments and Referral Authorities in the NW region) improve land delivery for housing production?
- What are the short-term and long-term relationships between housing affordability and housing land supply, in the North West Melbourne corridor. For example is there capacity to meet the demand in population growth and what are the implications of the Urban Growth Boundary?
This work will focus on associations between land administration and housing supply, and then between housing supply and housing affordability.
We will examine governance factors that constrain land supply (for example the urban growth boundary and zoning restrictions, planning permits).
The choice of location is generally influenced by the house price and the household ability to pay. On the supply side, house prices are a function of land cost plus the improved value (building).
Currently, the activities of government agencies that perform land administration functions, especially land use are disparate and lack harmonisation (Williamson et al 2010). The current arrangement is narrowly focused on statutory land use planning systems (development assessment) thereby leaving out a broader national strategic land use planning issues (COAG, 2011, Grattan Institute, 2011) that help determine the efficient location of uses and functioning of cities.
End Users and Products
This demonstrator will produce a dynamic web mapping application aimed at generating a Residential Development Potential Index (RDPI) for the North West Melbourne Region. Tools developed for reporting on this RDPI will include reporting and analysis outcomes.
