Do I Need Planning Permission for an Extension?

Do I Need Planning Permission for an Extension?

Not always.

Many house extensions can be built under permitted development rights without requiring a full planning application.

However, this depends on the size, design and location of the proposed extension.

What Is Permitted Development?

Permitted development rights allow certain types of development to proceed without planning permission.

These rights are subject to specific limitations and conditions.

Factors may include:

• the size of the extension,

• its height,

• proximity to boundaries,

• and previous extensions carried out at the property.

When Is Planning Permission Required?

Planning permission may be required where:

• permitted development limits are exceeded,

• the property is located in a conservation area,

• permitted development rights have been removed,

• or the proposal significantly alters the appearance of the property.

Will the Council Consider Neighbour Impact?

Yes.

Where planning permission is required, councils will often assess:

• overlooking,

• loss of light,

• design,

• and the impact on neighbouring properties.

Final Thoughts

Many extensions can proceed without planning permission.

However, obtaining professional advice before starting work can help avoid costly mistakes and potential enforcement issues.
