Before you decide in Windsor
Owners in Windsor and places nearby such as Slough, Egham and Staines-upon-Thames may find their address falls under a different planning authority from the one they expect. Each has its own validation list, design guidance, pre-application service and fees.
We confirm the correct authority at appraisal stage and prepare the application to its requirements. If your address is with the Royal Borough of Windsor and Maidenhead, we work to its validation list and guidance; if not, we work to whichever council covers your plot, so nothing is rejected on a technicality.
From first call to decision
To start, send us your Windsor address and a few photos of the garden, or give us a call. We check the title, access, constraints and nearby planning history, then talk it through with you. If the plot looks viable, we visit, explain whether an application is worth making and set out our fee and likely survey costs in writing.
Free plot appraisal
We review the title plan, access, constraints, policy and planning history around your address, then talk it through with you. If the plot looks viable we visit, and tell you plainly whether an application is worth making.
Surveys and design
A measured survey comes first, followed by the specialist surveys the plot needs, such as trees or ecology. The layout is designed around access, privacy, daylight, parking, bins and garden space for both homes.
Submit and manage
We complete the forms, ownership certificate, drawings and statements, pay the fee on your behalf and submit. During consultation we answer officers’ questions, respond to consultees and agree amendments where they help.
Decision and next steps
If permission is granted, we explain every condition and what must happen before work starts. If it’s refused, we review the reasons with you and set out the options: amend and resubmit, appeal, or stop.
Worth checking early
- Planning is the council’s decision; even a well-prepared application can be refused, and the costs of preparing it aren’t recovered.
- Specialist surveys can be needed at short notice when a consultee raises an issue, adding cost and time.
- Conditions can add cost and work before building starts, such as approved drainage details, tree protection or a construction management plan.
Questions about garden plots in Windsor
How close to neighbours can a new home in Windsor be?
It depends on the council’s guidance and the window layout. Many councils use around 21 metres between facing back windows and around 12 to 15 metres between a back window and a blank side wall, but the guide used by the Royal Borough of Windsor and Maidenhead decides. Screening, levels, roof form and window positions can all change what is acceptable.
Is pre-application advice available in Windsor?
Most planning authorities, including the Royal Borough of Windsor and Maidenhead, offer pre-application advice, usually for a fee, with their own response times. It isn’t compulsory and doesn’t bind the final decision, but for a garden plot with a tight access, strict policy or an earlier refusal, it can show which issues to resolve before you apply formally.
How long will my Windsor garden plot application take?
The statutory period for a minor application, such as one or a few new homes, is 8 weeks from validation, in both England and Wales. Many take longer, and the council may ask you to agree an extension in writing. If no decision is made in time and no extension is agreed, you can appeal for non-determination.
Can I sell my Windsor garden plot once it has planning permission?
Yes. Planning permission stays with the land, so the plot can be sold with it and the buyer can build the approved scheme, subject to any conditions. The plot will need its own title through a transfer of part at HM Land Registry, and any mortgage lender will need to release it. Take advice from a tax adviser before selling.
