What does 'additional information' mean on a planning application? Developers have applied for a high density (mainly apartments) housing complex behind my parents home (houses in the area are generally detached/semi-detached). The planning authority (Fingal coco) have asked for additional information instead of an outright rejection - one of the items requested a resubmission based on a maximum of 50-60 units per hectare instead of the 84 in the original plans. Does this mean the coco have bought into the idea of 50-60 units per hectare if other bits and pieces are complied with or could they still reject outright? The thing is so hideous and large that all the residents were sure it would be rejected outright - should they worry that additional information has been sought with suggestions for reduced (but still v high for the area) density?
