If you’re looking to add space, light, and value to your home without the complexity of a full planning application, a single storey rear extension is often the ideal solution.

In most cases, these extensions can be built under Permitted Development rights, meaning planning permission isn’t required — as long as the design meets certain size and placement criteria. However, there are important exceptions. If your property is in a conservation area, is statutorily listed, or is a flat or maisonette, full planning permission will be necessary.

To protect your investment and avoid potential disputes down the line, we strongly recommend securing a Lawful Development Certificate (LDC). This formal confirmation from your local authority verifies that your proposed extension is legal under current planning law — giving you peace of mind before construction begins.

It’s also essential to obtain Building Control approval, regardless of whether planning is required. This ensures your extension meets all structural, thermal, and safety standards — and prevents costly issues during or after the build.

At Don’t Move Extend, we handle the entire process — from initial concept and design to submitting applications, coordinating with consultants, and making sure every drawing lines up with your goals and your builder’s needs.
