Our neighbour behind us is building flats which we have no problem with as there are already similar flats. The building has been going on for almost 2 years and is still not finished (although hopefully soon). What I do have an issue with is that they have built a small balcony, and only today ripped out one of the windows and made a hole quite clearly to install a door to the balcony. The tenants will be able to oversee our garden and conservatory very easily!!!
I've checked the local council's website to see what plans were submitted and approved and there is nothing in the drawings that show a balcony and door, plus the conditions of approval quite clearly state the flat facing us will not have any external amenity space. To me they have breached the planning approval.
AIBU to want to dob them in to the council? Our garden is very small and I feel like this balcony will invade our privacy.
