Any planning experts here? A tenant farmer applied for and was granted permission to build a livestock shelter on the basis of his specific need for somewhere to lamb (the permission makes this very clear). Tenant then moves away when the building was at foundations level and has nothing more to do with it. Landowner (who does not have the same need - he's not a farmer) then continues to build, but does so in a way that is totally at odds with what was consented (two stories not one, insulated walls, windows in different places, stone roof not metal sheet, adds a toilet and septic etc). Can you just 'take over' a planning consent if you're the landowner?
