Higher proportions of affordable housing where viable and justified

However, it should also be noted that where it can be demonstrated that it is necessary and viable to provide a higher proportion of affordable housing, the Council will expect developments to do so. In this context, it is important to note that KSRs pertaining to certain larger housing sites in the plan may seek a higher contribution of affordable housing. Other Supplementary Planning Guidance (SPG), in the form of master plans, should also be taken into account where relevant, depending on the location of a specific development.
