I have a chalet style house with a large dormer in the sloping roof at the front. I applied for a 2 storey side extension which failed. i then spoke to council with regards what i needed to do to obtain permission these changes were made but now they are saying existing dormer looks to big can i make smaller or make 2 dormers, both these options are totally impractible. I dont want to resubmit until i am confident it should pass. my question is can they fail an application based on an existing feature which is not being changed or included within the new extension
