🏗️ Do I Need Planning Permission for House Extensions?

In many cases, Permitted Development Rights allow homeowners in Merton, Wimbledon, Kingston, Richmond, Sutton, and the wider South West London area to extend their properties without needing full planning permission, provided they meet certain standards. To help you determine whether your extension requires permission, here are some key guidelines:

✅ The extension doesn’t exceed 50% of the total land area around the original property
✅ It doesn’t extend beyond the principal or side elevation when facing a highway
✅ Materials used match or are similar to those on the existing exterior
✅ Single-storey extensions are no taller than 4m (8m for double-storey extensions)
✅ Side extensions don’t exceed half the width of the original home
✅ Single-storey rear extensions don’t extend more than 4m (detached homes) or 3m (attached homes) beyond the rear of the original property
✅ The eaves and ridge heights aren’t higher than the existing house

Keep in mind that if your property is listed or on designated land (such as conservation areas), these conditions may not apply, and additional permissions may be required.

5 Common House Extension Types

1. Rear Extension: A classic choice that extends your home into your garden, creating additional space for dining areas or entertainment zones. Ideal for properties without a side return.

2. Side Return Extension: Maximize the use of the side alleyway between your home and your neighbor’s property. Perfect for widening your kitchen without sacrificing garden space.

3. Wrap Around Extension: Combining the best of rear and side return extensions, this L-shaped design offers a dramatic increase in living space, transforming your kitchen and home’s overall feel.

4. Over-Structure Extension: Build above an existing structure, such as a garage, without encroaching on your precious garden area. A smart solution for preserving outdoor space.

5. Double Storey Extension: Maximize your extension’s potential by adding an extra level, allowing for additional rooms like bedrooms or a loft conversion. A comprehensive solution for those seeking maximum space.
