People need houses of a reasonable size in which to live. This should be applied across market and affordable housing so as not to discriminate against social housing residents.
Housing for the elderly should be mandatory across market and affordable housing. As sites have been selected, then this requirement can be site specific as to where they are best located for services etc.. However, it does not mean that other development sites must not contribute to the costs of the preferred sites.
Work needs to be done to ensure that developers do not take a 'phased' approach by only registering a smaller site to start with and then increasing the size by a smaller amount each time to ensure that they do not have to meet these standards. If land surrounding a site is put up for development, then the this must be considered as an extension to the original development, and the requirements for house sizes and housing for the elderly must be applied as a total and not as a smaller independent development. This should be in the form of a new policy.
