Proposal
Introduction of additional cross-corridor fire-rated walls incorporating fire door sets to match the style of existing adjacent door sets, fire-rated ceiling with (hidden) bulkhead, which continues the plane of existing adjacent ceilings wherever new door set locations cause a step in the fire compartment line and localised investigatory works may be necessary to inspect and potentially remedy earlier construction methods, materials and fire-stopping details and install and integrate a new cooling system.

What happens while it is decided
The process from here
This application is with Westminster for determination. The council publicises it, consults neighbours and technical bodies where required, and weighs the responses against local and national planning policy.
The statutory target is eight weeks for most applications and thirteen for major development, though extensions of time are common. Comments carry most weight while the case is undecided, so check the council portal for the deadline if you want to respond.
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.
