What happens while it is decided
The process from here
This application is with Hounslow 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 lawful development applications
How this application type works
A lawful development certificate is a legal determination, not a planning judgement. It asks the council to confirm either that existing use or works are lawful, often through the passage of time, or that a proposal would not need planning permission at all. The applicant must prove the facts; the merits of the scheme are not considered.

P/2025/3208 Withdrawn
Oldfield House, Flat 3 Devonshire Road Chiswick London Hounslow W4 2AP
The proposed works involve kitchen renovation, including the installation of new kitchen cabinetry. There is a larder within the kitchen that houses the gas meter. We are uncertain whether the wall enclosing the larder is load-bearing. The intention is to remove this small wall to allow the new cabinetry and worktop to extend seamlessly across the space.
