Why Planning Permission isn’t a guarantee even if your neighbour has already done the same.
Just because your neighbour received planning permission doesn’t mean your project will automatically be approved. Each application is assessed individually, based on property type, location, design, and current planning policies. Checking local guidelines and consulting the planning office can improve your chances of success.
If our neighbours have carried out similar work to what we want to do, surely we won’t have any planning issues?
Many homeowners ask this question, and it’s easy to see why. If your neighbour has built a similar extension or made exterior changes that you like, it seems reasonable to assume you can do the same. However, planning approval doesn’t work that way.
Just because a nearby property received planning permission does not mean your project will automatically be approved. Every application is assessed on its own merits, and several factors can affect the outcome.

Reasons why planning permission it may not be so straightforward
Properly Approved Extensions:
Even if your neighbour has received proper planning permission and constructed their project accordingly, it is unwise to assume you can achieve the same result. The best way to safeguard your interests, reducing stress, sleepless nights, and protecting your finances is to assess your planning possibilities from the ground up. Use a strategic, well-tested approach to explore your permitted development options.
Extensions without Planning Permission:
Sometimes, a neighbour may have constructed an extension without obtaining the necessary planning permission, even if they claimed they did. We’ve encountered this situation several times (especially if the current owner did not carry out the extension). In such cases, the neighbour risks enforcement action, which could lead to demolition orders, penalties, and potential criminal investigations.
Deviation from Approved Plans:
Another scenario involves a neighbour who has obtained planning permission but built something slightly different from what was approved. Imitating their project could expose you to similar enforcement actions, which may lead to significant financial (and emotional) setbacks. It’s essential not to succumb to the temptation of taking shortcuts.
Best Steps to Take:
- Check Planning Restrictions: Determine whether you are in an Article 2(3) land designation, such as a conservation area, or if your property is listed. Identify any restrictions on your permitted development rights that could limit your options without planning permission.
- Local Planning Policy: Investigate whether the local planning policy will support your intended project or what you can afford.
- Consider Local Precedents: Research local precedents. This should include your neighbours’ properties and any examples that have successfully navigated the planning system. Use this information to inform your budget and project requirements. There is no point in pursuing planning for something that does not meet your core needs or is beyond your financial capacity.
Remember, when it comes to planning and your neighbours:
Your neighbour’s success can be a good starting point, but it’s not a guarantee. Each property has its own context, and each planning application stands on its own. With the right preparation and advice, you can improve your chances and move forward with confidence.
