This policy reflects existing policies in both the Cambridge City Local Plan and South Cambridgeshire Local Plan, and it will important that the Council has sufficient evidence to support their continued inclusion in the Greater Cambridge Local Plan. With regard to Part M4(2) we would suggest that some consideration be given to the accessibility of the existing stock and degree to which those with mobility difficulties will be able to adapt their own home to meet their needs. With regard to both space standards and accessibility standards it will be necessary to examine the impact the implementation of these standards has had on development, in particular on windfall sites and whether it has limited opportunities in Cambridge. We note that the Homes Topic paper mentions that the application of part M4(2) has been challenging in some instances and it will be important that this policy is sufficiently flexible to ensure schemes where it is either unfeasible or unviable to deliver these standards can still come forward.
