FAQ
Planning approvals in Kingston upon Thames — common questions
Questions homeowners ask about planning approvals and the application process.
How do I find recent planning approvals in Kingston upon Thames?
You can search the Royal Borough of Kingston upon Thames public planning register for recent decisions. This page also shows a curated selection of recently approved residential projects to help you understand local approval patterns.
What types of planning applications are most commonly approved in Kingston upon Thames?
Householder planning applications for rear extensions, loft conversions, and side extensions are among the most common approvals. Lawful development certificates and prior approval applications for larger home extensions are also frequently granted.
Does a previous approval in Kingston upon Thames guarantee my application will be approved?
No. Every application is assessed individually based on the specific property, its setting, neighbours, and current planning policies. Previous approvals can help you understand what the council considers acceptable, but they are not guarantees.
How can Crown Architecture help with my planning application in Kingston upon Thames?
Crown Architecture can review your property, advise on the most appropriate application route (planning permission, lawful development certificate, or prior approval), prepare measured survey drawings, existing and proposed plans, elevations, and supporting documents, and manage the submission to Royal Borough of Kingston upon Thames.
What is a Lawful Development Certificate?
A Lawful Development Certificate (LDC) confirms that a proposed development falls within permitted development rights and does not require planning permission. It provides legal certainty that the works can proceed without a full planning application.
What is prior approval for a larger home extension?
Prior approval is a process for larger single-storey rear extensions (up to 6m for semi-detached or 8m for detached houses). The council assesses neighbour impact rather than design quality. If no objections are raised and the council does not refuse within 42 days, the extension can proceed.
