Each sample gives a clear verdict, such as “rear extension: likely yes”, plus nearby houses and what to do next. They are examples, not a live answer for a house today.

What this report is for
One house as it stands, and the same house with work added. The report says which of those changes are likely, from decisions on nearby homes.
The researched Valley Road, Fawkham sample. Green Belt applies, and it does not remove permitted development. A single-storey rear extension, a loft within the limits, and an outbuilding are a likely yes. A two-storey extension is unlikely.
