Can I Use Permitted Development Rights to Build an Extension in Milton Keynes?
Many homeowners in Milton Keynes want to extend their homes but are unsure if they need planning permission. Fortunately, Permitted Development rights for an extension in Milton Keynes allows a homeowner to extend their home without requiring full approval from the council. However, these rights come with restrictions.
In this article, we will walk through what Permitted Development (PD) rights include, their limitations, and what to do if your extension falls outside these guidelines.
What Are Permitted Development Rights?
Permitted Development rights are government policies that allow homeowners to make certain improvements to their properties without needing formal planning permission. They provide a faster, simpler, and more affordable way to expand your home.
Do You Need Planning Permission for an Extension in Milton Keynes?
Not all extensions require planning permission. If your project meets PD rights criteria, you can proceed without applying for approval. However, if your extension exceeds these limitations, you’ll need to apply for full planning permission from Milton Keynes Council.
Key Permitted Development Rules for Extensions
To qualify under Permitted Development rights in Milton Keynes, your extension must:
Be a single-storey rear extension extending up to 6m for a semi-detached or 8m for a detached house.
Not exceed 50% of the total land area around the original house.
Not be taller than 4m.
Use materials similar to the existing property.
Not extend beyond the principal elevation (front of the house).
The information regarding extending your home under Permitted Development rights is based on the UK Government’s guidelines. Specifically, the Larger Home Extension Scheme allows:
Detached houses: Single-storey rear extensions up to 8 metres beyond the original rear wall.
Semi-detached and terraced houses: Single-storey rear extensions up to 6 metres beyond the original rear wall.
These allowances are subject to specific conditions and require a prior approval process with your local planning authority. For detailed technical guidance, you can refer to the UK Government’s publication on Permitted Development rights for householders. GOV.UK
Additionally, the Planning Portal provides comprehensive information on common projects, including extensions, which can help you understand the limitations and conditions associated with Permitted Development rights. Planning Portal
It’s essential to consult these resources and your local planning authority to ensure your proposed extension complies with all relevant regulations.
When Do You Need Full Planning Permission?
If your extension does not comply with PD rights, you’ll need to apply for full planning permission. This applies if:
Your home is in a conservation area or is listed.
The extension exceeds the size limits of PD rights.
Your home has had PD rights removed by the local council.
You are planning a two-storey extension.
