Without planning permission it is very difficult to sell or rent a property, so although some developers take a risk and build without planning permission, they take a huge risk in doing so.

The council should consider the application on its merits and if the development is overlooking houses or gardens, does not have adequate amenity space, and a whole host of other planning regulations - then the council can refuse to grant planning permission and force demolition or conformity with the planning permission that has been granted. Sometimes a compromise can be reached that brings the development in line with planning guidance.

As I say, each planning application must be considered on its own merits, but the planning department do not look favourably on breeches of this nature, especially if planning permission was granted for something substantially different.

Please let us know the planning application number when it is submitted or contact me by PM (Private Message) if I can be any help to you.
