Planning: Research

Volume 468: debated on Thursday 29 November 2007

To ask the Secretary of State for Communities and Local Government what research (a) commissioned and (b) evaluated by her Department was taken account of in reaching the decision on new homes in the current plan period; and if she will make a statement. (165045)

In order to respond to the Barker review of housing supply, the Department commissioned the university of Reading to develop a theoretical affordability model that models the impact of different levels and regional distributions of housing supply on affordability. This research was published at the time of the Government's response to the Barker review in November 2005, and is available on the Department's website:

Since then the university of Reading has continued to develop the model, and the Department will be publishing details of the latest version of this model in due course.

The National Housing and Planning Advice Unit (NHPAU) has recently published a response to the Government's housing Green Paper, which used this model to examine a range of housebuilding scenarios.

In addition to the research outlined above, a range of other evidence and analysis was used as part of the decision-making process underlying the housing Green Paper announcement that 3 million homes would be built by 2020. This included the official household projections produced by the Department and examination of housing supply data and the regional plans existing at that time.
