EMP5 Mix of Unit Sizes
In the designated employment areas a mix of unit sizes will be required. On development sites over two hectares in area, there will be a requirement for a minimum of 10% of the net floorspace area within the site to be developed for small and/or medium sized units for business or industrial uses within use Class B. This policy will not apply in the case of existing companies, which are developing large sites for their own expansion.
