Do I Need Planning Permission for My Project?

If you’re thinking about extending, converting, or reworking your home, one of the first things

to figure out is whether you’ll need planning permission. The answer? It depends on what you’re planning, where you live, and how your home has been altered in the past.

Some smaller changes can go ahead under Permitted Development Rights, meaning you may not need to submit a full application. Others, especially larger or more visible changes, will need formal approval from your local authority.

So how can you tell?

You might not need planning permission if:

•  You’re building a modest single-storey rear extension

•  The materials match your existing home

•  You’re staying within height and boundary limits

•  Your project doesn’t face the road or affect a neighbour’s privacy

  
  

You will likely need permission if:

•  Your home is in a conservation area or is listed

•  You’re changing the roofline, adding a dormer, or building above one storey

•  You’re planning a significant change to the appearance or footprint

•  There are covenants, easements, or previous planning restrictions on your property

Getting it wrong can mean refused applications, costly redesigns, or worse, being forced to undo completed work.
