What a grant of permission means
The process from here
Permission has been granted, usually subject to conditions listed on the decision notice, some of which must be discharged before work starts. The decision notice on the council portal sets out exactly what was approved.
Work must normally begin within three years of the decision or the permission lapses. Neighbours cannot appeal a grant; challenging one means judicial review of how the decision was made, within tight time limits.
About heritage and listed buildings applications
How this application type works
Heritage applications concern listed buildings and conservation areas. Listed building consent is needed for works, inside or out, that affect the special interest of a listed building, and carrying out such works without consent is a criminal offence. The council weighs harm to the heritage asset against any public benefit of the proposal.

P2026/1153/LBC Awaiting decision
9, Brooksby Street, London, N1 1EX
The property is a late Georgian maisonette, part of a terrace of four storey houses in the Barnsbury Conservation Area. The proposal is to replace a modern and rotten timber threshold (backdoor step) with a natural sawn buff Yorkstone step to match the traditional masonry found in the Barnsbury Conservation Area. The step will enhance the building's longevity, protect the fabric of the building, and is more consistent with the traditional materials used in Islington's historic fabric.
