Do I need planning permission for an extension in Bromsgrove or Redditch?

Short answer: often no — but the details matter.

Permitted Development, briefly

The government allows certain extensions without a full planning application, under what's called Permitted Development (PD). In broad terms, on an unlisted house outside a conservation area, you can usually build:

• A single-storey rear extension up to 4 m deep on a detached house, 3 m on a semi or terrace.
• A larger single-storey rear (up to 8 m detached / 6 m attached) under the "Larger Home Extension" prior-approval route.
• A side extension up to half the width of the original house, single-storey only.
• A two-storey rear extension up to 3 m deep, with restrictions on roof pitch and eaves height.

When you always need permission

You almost certainly need a full application if:

• The property is listed or in a conservation area.
• The extension goes forward of the principal elevation.
• You've already used PD rights on the house.
• You want to add balconies, verandas or raised platforms.

Bromsgrove and Redditch specifics

Bromsgrove District Council and Redditch Borough Council both have local plans that layer additional constraints in some parts of the borough — particularly around the conservation villages we work in. We check the Article 4 directions and any local designations as part of every quote.
