That may have been the case if you could put in the application without disclosing the other land but I don't think you would get PD for the size buildings you require just disclosing the 18.5ac and the 5.5ac wouldn't qualify for PD on its own so you would have to include both parcels in the application and then the two authorities will probably consult each other to ensure you haven't made applications on both plots.Yup, that's the plan. There's a few strands to the expansion so I'll get it all noted and sent off with the application.
One thing my consultant said was that because my two plots are in different planning areas (we're right on the border with one of them, it literally runs down the edge of our field), they might be a little less fussy as it's 'not on my patch'.
