Planning applications are based on a need and a proof they are required. Not just by the applicant but by the wider community. Feelings, thoughts, opinions are not a factor in opposition. Over development, zero community benefit and disturbance of natural habitat are as well as some visuals but there is always scope to add modern looking facilities into very old areas such as modern structures in old city centres. It doesn't happen overnight. The planning are very intricate down to what grounds maintenance is done, does it promote bio diversity, is the interior of a green make up ( all that carbon zero stuff), objections researched, even as far as material suppliers do make their products correctly ( no slave labour, child labour). Don't be so impatient.
Edit: forgot to mention that certain unamed people get a brown envelope. Very important in negotiations.
